Expect details of the API, defaults, and supported capabilities to change before general availability, and expect more advanced features over time. + +Modern agents work best when they can operate on real files in a filesystem. **Sandbox Agents** can make use of specialized tools and shell commands to search over and manipulate large document sets, edit files, generate artifacts, and run commands. The sandbox provides the model with a persistent workspace that the agent can use to do work on your behalf. Sandbox Agents in the Agents SDK help you easily run agents paired with a sandbox environment, making it easy to get the right files on the filesystem and orchestrate the sandboxes to make it easy to start, stop, and resume tasks at scale. + +You define the workspace around the data the agent needs. It can start from GitHub repos, local files and directories, synthetic task files, remote filesystems such as S3 or Azure Blob Storage, and other sandbox inputs you provide. + +

+ +`SandboxAgent` is still an `Agent`. It keeps the usual agent surface such as `instructions`, `prompt`, `tools`, `handoffs`, `mcp_servers`, `model_settings`, `output_type`, guardrails, and hooks, and it still runs through the normal `Runner` APIs. What changes is the execution boundary: + +- `SandboxAgent` defines the agent itself: the usual agent configuration plus sandbox-specific defaults like `default_manifest`, `base_instructions`, `run_as`, and capabilities such as filesystem tools, shell access, skills, memory, or compaction. +- `Manifest` declares the desired starting contents and layout for a fresh sandbox workspace, including files, repos, mounts, and environment. +- A sandbox session is the live isolated environment where commands run and files change. +- [`SandboxRunConfig`][agents.run_config.SandboxRunConfig] decides how the run gets that sandbox session, for example by injecting one directly, reconnecting from serialized sandbox session state, or creating a fresh sandbox session through a sandbox client. +- Saved sandbox state and snapshots let later runs reconnect to prior work or seed a fresh sandbox session from saved contents. + +`Manifest` is the fresh-session workspace contract, not the full source of truth for every live sandbox. The effective workspace for a run can instead come from a reused sandbox session, serialized sandbox session state, or a snapshot chosen at run time. + +Throughout this page, "sandbox session" means the live execution environment managed by a sandbox client. It is different from the SDK's conversational [`Session`][agents.memory.session.Session] interfaces described in [Sessions](../sessions/index.md). + +The outer runtime still owns approvals, tracing, handoffs, and resume bookkeeping. The sandbox session owns commands, file changes, and environment isolation. That split is a core part of the model. + +### How the pieces fit together + +A sandbox run combines an agent definition with per-run sandbox configuration.

Move to `DockerSandboxClient` when you need container isolation or image parity. Move to a hosted provider when you need provider-managed execution. + +In most cases, the `SandboxAgent` definition stays the same while the sandbox client and its options change in [`SandboxRunConfig`][agents.run_config.SandboxRunConfig]. See [Sandbox clients](clients.md) for local, Docker, hosted, and remote-mount options. + +## Core pieces + +
+ +| Layer | Main SDK pieces | What it answers | +| --- | --- | --- | +| Agent definition | `SandboxAgent`, `Manifest`, capabilities | What agent will run, and what fresh-session workspace contract should it start from? | +| Sandbox execution | `SandboxRunConfig`, the sandbox client, and the live sandbox session | How does this run get a live sandbox session, and where does the work execute? | +| Saved sandbox state | `RunState` sandbox payload, `session_state`, and snapshots | How does this workflow reconnect to prior sandbox work or seed a fresh sandbox session from saved contents? | + +
+ +The main SDK pieces map onto those layers like this: + +
+ +| Piece | What it owns | Ask this question | +| --- | --- | --- | +| [`SandboxAgent`][agents.sandbox.sandbox_agent.SandboxAgent] | The agent definition | What should this agent do, and which defaults should travel with it? | +| [`Manifest`][agents.sandbox.manifest.Manifest] | Fresh-session workspace files and folders | What files and folder should be present on the filesystem when the run starts? | +| [`Capability`][agents.sandbox.capabilities.capability.Capability] | Sandbox-native behavior | Which tools, instruction fragments, or runtime behavior should attach to this agent? | +| [`SandboxRunConfig`][agents.run_config.SandboxRunConfig] | Per-run sandbox client and sandbox-session source | Should this run inject, resume, or create a sandbox session? | +| [`RunState`][agents.run_state.RunState] | Runner-managed saved sandbox state | Am I resuming a prior runner-managed workflow and carrying its sandbox state forward automatically? | +| [`SandboxRunConfig.session_state`][agents.run_config.SandboxRunConfig.session_state] | Explicit serialized sandbox session state | Do I want to resume from sandbox state I already serialized outside `RunState`? | +| [`SandboxRunConfig.snapshot`][agents.run_config.SandboxRunConfig.snapshot] | Saved workspace contents for fresh sandbox sessions | Should a new sandbox session start from saved files and artifacts? | + +
+ +A practical design order is: + +1. Define the fresh-session workspace contract with `Manifest`. +2. Define the agent with `SandboxAgent`. +3. Add built-in or custom capabilities. +4. Decide how each run should obtain its sandbox session in `RunConfig(sandbox=SandboxRunConfig(...))`. + +## How a sandbox run is prepared + +At run time, the runner turns that definition into a concrete sandbox-backed run: + +1. It resolves the sandbox session from `SandboxRunConfig`. + If you pass `session=...`, it reuses that live sandbox session. + Otherwise it uses `client=...` to create or resume one. +2. It determines the effective workspace inputs for the run. + If the run injects or resumes a sandbox session, that existing sandbox state wins. + Otherwise the runner starts from a one-off manifest override or `agent.default_manifest`. + This is why `Manifest` alone does not define the final live workspace for every run. +3. It lets capabilities process the resulting manifest. + This is how capabilities can add files, mounts, or other workspace-scoped behavior before the final agent is prepared. +4. It builds the final instructions in a fixed order: + the SDK's default sandbox prompt, or `base_instructions` if you explicitly override it, then `instructions`, then capability instruction fragments, then any remote-mount policy text, then a rendered filesystem tree. +5. It binds capability tools to the live sandbox session and runs the prepared agent through the normal `Runner` APIs. + +Sandboxing does not change what a turn means. A turn is still a model step, not a single shell command or sandbox action. There is no fixed 1:1 mapping between sandbox-side operations and turns: some work may stay inside the sandbox execution layer, while other actions return tool results, approvals, or other state that requires another model step. As a practical rule, another turn is consumed only when the agent runtime needs another model response after sandbox work has happened. + +Those preparation steps are why `default_manifest`, `instructions`, `base_instructions`, `capabilities`, and `run_as` are the main sandbox-specific options to think about when designing a `SandboxAgent`. + +## `SandboxAgent` options + +These are the sandbox-specific options on top of the usual `Agent` fields: + +
+ +| Option | Best use | +| --- | --- | +| `default_manifest` | The default workspace for fresh sandbox sessions created by the runner. | +| `instructions` | Additional role, workflow, and success criteria appended after the SDK sandbox prompt. | +| `base_instructions` | Advanced escape hatch that replaces the SDK sandbox prompt. | +| `capabilities` | Sandbox-native tools and behavior that should travel with this agent. | +| `run_as` | User identity for model-facing sandbox tools such as shell commands, file reads, and patches. | + +
+ +Sandbox client choice, sandbox-session reuse, manifest override, and snapshot selection belong in [`SandboxRunConfig`][agents.run_config.SandboxRunConfig], not on the agent. + +### `default_manifest` + +`default_manifest` is the default [`Manifest`][agents.sandbox.manifest.Manifest] used when the runner creates a fresh sandbox session for this agent. Use it for the files, repos, helper material, output directories, and mounts the agent should usually start with. + +This is only the default. A run can override it with `SandboxRunConfig(manifest=...)`, and a reused or resumed sandbox session keeps its existing workspace state. + +### `instructions` and `base_instructions` + +Use `instructions` for short rules that should survive different prompts. In a `SandboxAgent`, these instructions are appended after the SDK's sandbox base prompt, so you keep the built-in sandbox guidance and add your own role, workflow, and success criteria. + +Use `base_instructions` only when you want to replace the SDK sandbox base prompt. Most agents should not set it. + +
+ +| Put it in... | Use it for | Examples | +| --- | --- | --- | +| `instructions` | Stable role, workflow rules, and success criteria for the agent. | "Inspect onboarding documents, then hand off.", "Write final files into `output/`." | +| `base_instructions` | A full replacement for the SDK sandbox base prompt. | Custom low-level sandbox wrapper prompts. | +| the user prompt | The one-off request for this run. | "Summarize this workspace." | +| workspace files in the manifest | Longer task specs, repo-local instructions, or bounded reference material. | `repo/task.md`, document bundles, sample packets. | + +
+ +Good uses for `instructions` include: + +- [examples/sandbox/unix_local_pty.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/unix_local_pty.py) keeps the agent in one interactive process when PTY state matters. +- [examples/sandbox/handoffs.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/handoffs.py) forbids the sandbox reviewer from answering the user directly after inspection. +- [examples/sandbox/tax_prep.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/tax_prep.py) requires the final filled files to actually land in `output/`. +- [examples/sandbox/docs/coding_task.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/docs/coding_task.py) pins the exact verification command and clarifies workspace-root-relative patch paths. + +Avoid copying the user's one-off task into `instructions`, embedding long reference material that belongs in the manifest, restating tool docs that built-in capabilities already inject, or mixing in local installation notes the model does not need at run time. + +If you omit `instructions`, the SDK still includes the default sandbox prompt. That is enough for low-level wrappers, but most user-facing agents should still provide explicit `instructions`. + +### `capabilities` + +Capabilities attach sandbox-native behavior to a `SandboxAgent`. They can shape the workspace before a run starts, append sandbox-specific instructions, expose tools that bind to the live sandbox session, and adjust model behavior or input handling for that agent. + +Built-in capabilities include: + +
+ +| Capability | Add it when | Notes | +| --- | --- | --- | +| `Shell` | The agent needs shell access. | Adds `exec_command`, plus `write_stdin` when the sandbox client supports PTY interaction. | +| `Filesystem` | The agent needs to edit files or inspect local images. | Adds `apply_patch` and `view_image`; patch paths are workspace-root-relative. | +| `Skills` | You want skill discovery and materialization in the sandbox. | Prefer this over mounting `.agents` or `.agents/skills` manually for sandbox-local `SKILL.md` skills. | +| `Memory` | Follow-on runs should read or generate memory artifacts. | Requires `Shell`; live updates also require `Filesystem`. | +| `Compaction` | Long-running flows need context trimming after compaction items. | Adjusts model sampling and input handling. | + +
+ +By default, `SandboxAgent.capabilities` uses `Capabilities.default()`, which includes `Filesystem()`, `Shell()`, and `Compaction()`. If you pass `capabilities=[...]`, that list replaces the default, so include any default capabilities you still want. + +For skills, choose the source based on how you want them materialized: + +- `Skills(lazy_from=LocalDirLazySkillSource(...))` is a good default for larger local skill directories because the model can discover the index first and load only what it needs. +- `Skills(from_=LocalDir(src=...))` is better for a small local bundle you want staged up front. +- `Skills(from_=GitRepo(repo=..., ref=...))` is the right fit when the skills themselves should come from a repository. + +If your skills already live on disk under something like `.agents/skills//SKILL.md`, point `LocalDir(...)` at that source root and still use `Skills(...)` to expose them. Keep the default `skills_path=".agents"` unless you have an existing workspace contract that depends on a different in-sandbox layout. + +Prefer built-in capabilities when they fit. Write a custom capability only when you need a sandbox-specific tool or instruction surface that the built-ins do not cover. + +## Concepts + +### Manifest + +A [`Manifest`][agents.sandbox.manifest.Manifest] describes the workspace for a fresh sandbox session. It can set the workspace `root`, declare files and directories, copy in local files, clone Git repos, attach remote storage mounts, set environment variables, and define users or groups. + +Manifest entry paths are workspace-relative. They cannot be absolute paths or escape the workspace with `..`, which keeps the workspace contract portable across local, Docker, and hosted clients. + +Use manifest entries for the material the agent needs before work begins: + +
+ +| Manifest entry | Use it for | +| --- | --- | +| `File`, `Dir` | Small synthetic inputs, helper files, or output directories. | +| `LocalFile`, `LocalDir` | Host files or directories that should be materialized into the sandbox. | +| `GitRepo` | A repository that should be fetched into the workspace. | +| mounts such as `S3Mount`, `GCSMount`, `R2Mount`, `AzureBlobMount`, `S3FilesMount` | External storage that should appear inside the sandbox. | + +
+ +Mount entries describe what storage to expose; mount strategies describe how a sandbox backend attaches that storage. See [Sandbox clients](clients.md#mounts-and-remote-storage) for mount options and provider support. + +Good manifest design usually means keeping the workspace contract narrow, putting long task recipes in workspace files such as `repo/task.md`, and using relative workspace paths in instructions, for example `repo/task.md` or `output/report.md`. If the agent edits files with the `Filesystem` capability's `apply_patch` tool, remember that patch paths are relative to the sandbox workspace root, not the shell `workdir`. + +### Permissions + +`Permissions` controls filesystem permissions for manifest entries. It is about the files the sandbox materializes, not model permissions, approval policy, or API credentials. + +By default, manifest entries are owner-readable/writable/executable and readable/executable by group and others. Override this when staged files should be private, read-only, or executable: + +```python +from agents.sandbox import FileMode, Permissions +from agents.sandbox.entries import File + +private_notes = File( + text="internal notes", + permissions=Permissions( + owner=FileMode.READ | FileMode.WRITE, + group=FileMode.NONE, + other=FileMode.NONE, + ), +) +``` + +`Permissions` stores separate owner, group, and other bits, plus whether the entry is a directory. You can build it directly, parse it from a mode string with `Permissions.from_str(...)`, or derive it from an OS mode with `Permissions.from_mode(...)`. + +Users are the sandbox identities that can execute work. Add a `User` to the manifest when you want that identity to exist in the sandbox, then set `SandboxAgent.run_as` when model-facing sandbox tools such as shell commands, file reads, and patches should run as that user. If `run_as` points at a user that is not already in the manifest, the runner adds it to the effective manifest for you. + +```python +from agents import Runner +from agents.run import RunConfig +from agents.sandbox import FileMode, Manifest, Permissions, SandboxAgent, SandboxRunConfig, User +from agents.sandbox.entries import Dir, LocalDir +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +analyst = User(name="analyst") + +agent = SandboxAgent( + name="Dataroom analyst", + instructions="Review the files in `dataroom/` and write findings to `output/`.", + default_manifest=Manifest( + # Declare the sandbox user so manifest entries can grant access to it. + users=[analyst], + entries={ + "dataroom": LocalDir( + src="./dataroom", + # Let the analyst traverse and read the mounted dataroom, but not edit it. + group=analyst, + permissions=Permissions( + owner=FileMode.READ | FileMode.EXEC, + group=FileMode.READ | FileMode.EXEC, + other=FileMode.NONE, + ), + ), + "output": Dir( + # Give the analyst a writable scratch/output directory for artifacts. + group=analyst, + permissions=Permissions( + owner=FileMode.ALL, + group=FileMode.ALL, + other=FileMode.NONE, + ), + ), + }, + ), + # Run model-facing sandbox actions as this user, so those permissions apply. + run_as=analyst, +) + +result = await Runner.run( + agent, + "Summarize the contracts and call out renewal dates.", + run_config=RunConfig( + sandbox=SandboxRunConfig(client=UnixLocalSandboxClient()), + ), +) +``` + +If you also need file-level sharing rules, combine users with manifest groups and entry `group` metadata. The `run_as` user controls who executes sandbox-native actions; `Permissions` controls which files that user can read, write, or execute once the sandbox has materialized the workspace. + +### SnapshotSpec + +`SnapshotSpec` tells a fresh sandbox session where saved workspace contents should be restored from and persisted back to. It is the snapshot policy for the sandbox workspace, while `session_state` is the serialized connection state for resuming a specific sandbox backend. + +Use `LocalSnapshotSpec` for local durable snapshots and `RemoteSnapshotSpec` when your app provides a remote snapshot client. A no-op snapshot is used as a fallback when local snapshot setup is unavailable, and advanced callers can use one explicitly when they do not want workspace snapshot persistence. + +```python +from pathlib import Path + +from agents.run import RunConfig +from agents.sandbox import LocalSnapshotSpec, SandboxRunConfig +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +run_config = RunConfig( + sandbox=SandboxRunConfig( + client=UnixLocalSandboxClient(), + snapshot=LocalSnapshotSpec(base_path=Path("/tmp/my-sandbox-snapshots")), + ) +) +``` + +When the runner creates a fresh sandbox session, the sandbox client builds a snapshot instance for that session. On start, if the snapshot is restorable, the sandbox restores saved workspace contents before the run continues. On cleanup, runner-owned sandbox sessions archive the workspace and persist it back through the snapshot. + +If you omit `snapshot`, the runtime tries to use a default local snapshot location when it can. If that cannot be set up, it falls back to a no-op snapshot. Mounted and ephemeral paths are not copied into snapshots as durable workspace contents. + +### Sandbox lifecycle + +There are two lifecycle modes: **SDK-owned** and **developer-owned**. + +
+ +```mermaid +sequenceDiagram + participant App + participant Runner + participant Client + participant Sandbox + + App->>Runner: Runner.run(..., SandboxRunConfig(client=...)) + Runner->>Client: create or resume sandbox + Client-->>Runner: sandbox session + Runner->>Sandbox: start, run tools + Runner->>Sandbox: stop and persist snapshot + Runner->>Client: delete runner-owned resources + + App->>Client: create(...) + Client-->>App: sandbox session + App->>Sandbox: async with sandbox + App->>Runner: Runner.run(..., SandboxRunConfig(session=sandbox)) + Runner->>Sandbox: run tools + App->>Sandbox: cleanup on context exit / aclose() +``` + +
+ +Use SDK-owned lifecycle when the sandbox only needs to live for one run. Pass a `client`, optional `manifest`, optional `snapshot`, and client `options`; the runner creates or resumes the sandbox, starts it, runs the agent, persists snapshot-backed workspace state, shuts the sandbox down, and lets the client clean up runner-owned resources. + +```python +result = await Runner.run( + agent, + "Inspect the workspace and summarize what changed.", + run_config=RunConfig( + sandbox=SandboxRunConfig(client=UnixLocalSandboxClient()), + ), +) +``` + +Use developer-owned lifecycle when you want to eagerly create a sandbox, reuse one live sandbox across multiple runs, inspect files after a run, stream over a sandbox you created yourself, or decide exactly when cleanup happens. Passing `session=...` tells the runner to use that live sandbox, but not to close it for you. + +```python +sandbox = await client.create(manifest=agent.default_manifest) + +async with sandbox: + run_config = RunConfig(sandbox=SandboxRunConfig(session=sandbox)) + await Runner.run(agent, "Analyze the files.", run_config=run_config) + await Runner.run(agent, "Write the final report.", run_config=run_config) +``` + +The context manager is the usual shape: it starts the sandbox on entry and runs the session cleanup lifecycle on exit. If your app cannot use a context manager, call the lifecycle methods directly: + +```python +sandbox = await client.create( + manifest=agent.default_manifest, + snapshot=LocalSnapshotSpec(base_path=Path("/tmp/my-sandbox-snapshots")), +) +try: + await sandbox.start() + await Runner.run( + agent, + "Analyze the files.", + run_config=RunConfig(sandbox=SandboxRunConfig(session=sandbox)), + ) + # Persist a checkpoint of the live workspace before doing more work. + # `aclose()` also calls `stop()`, so this is only needed for an explicit mid-lifecycle save. + await sandbox.stop() +finally: + await sandbox.aclose() +``` + +`stop()` only persists snapshot-backed workspace contents; it does not tear down the sandbox. `aclose()` is the full session cleanup path: it runs pre-stop hooks, calls `stop()`, shuts down sandbox resources, and closes session-scoped dependencies. + +## `SandboxRunConfig` options + +[`SandboxRunConfig`][agents.run_config.SandboxRunConfig] holds the per-run options that decide where the sandbox session comes from and how a fresh session should be initialized. + +### Sandbox source + +These options decide whether the runner should reuse, resume, or create the sandbox session: + +
+ +| Option | Use it when | Notes | +| --- | --- | --- | +| `client` | You want the runner to create, resume, and clean up sandbox sessions for you. | Required unless you provide a live sandbox `session`. | +| `session` | You already created a live sandbox session yourself. | The caller owns lifecycle; the runner reuses that live sandbox session. | +| `session_state` | You have serialized sandbox session state but not a live sandbox session object. | Requires `client`; the runner resumes from that explicit state as an owning session. | + +
+ +In practice, the runner resolves the sandbox session in this order: + +1. If you inject `run_config.sandbox.session`, that live sandbox session is reused directly. +2. Otherwise, if the run is resuming from `RunState`, the stored sandbox session state is resumed. +3. Otherwise, if you pass `run_config.sandbox.session_state`, the runner resumes from that explicit serialized sandbox session state. +4. Otherwise, the runner creates a fresh sandbox session. For that fresh session, it uses `run_config.sandbox.manifest` when provided, or `agent.default_manifest` if not. + +### Fresh-session inputs + +These options only matter when the runner is creating a fresh sandbox session: + +
+ +| Option | Use it when | Notes | +| --- | --- | --- | +| `manifest` | You want a one-off fresh-session workspace override. | Falls back to `agent.default_manifest` when omitted. | +| `snapshot` | A fresh sandbox session should be seeded from a snapshot. | Useful for resume-like flows or remote snapshot clients. | +| `options` | The sandbox client needs creation-time options. | Common for Docker images, Modal app names, E2B templates, timeouts, and similar client-specific settings. | + +
+ +### Materialization controls + +`concurrency_limits` controls how much sandbox materialization work can run in parallel. Use `SandboxConcurrencyLimits(manifest_entries=..., local_dir_files=...)` when large manifests or local directory copies need tighter resource control. Set either value to `None` to disable that specific limit. + +A few implications are worth keeping in mind: + +- Fresh sessions: `manifest=` and `snapshot=` only apply when the runner is creating a fresh sandbox session. +- Resume vs snapshot: `session_state=` reconnects to previously serialized sandbox state, whereas `snapshot=` seeds a new sandbox session from saved workspace contents. +- Client-specific options: `options=` depends on the sandbox client; Docker and many hosted clients require it. +- Injected live sessions: if you pass a running sandbox `session`, capability-driven manifest updates can add compatible non-mount entries. They cannot change `manifest.root`, `manifest.environment`, `manifest.users`, or `manifest.groups`; remove existing entries; replace entry types; or add or change mount entries. +- Runner API: `SandboxAgent` execution still uses the normal `Runner.run()`, `Runner.run_sync()`, and `Runner.run_streamed()` APIs. + +## Full example: coding task + +This coding-style example is a good default starting point: + +```python +import asyncio +from pathlib import Path + +from agents import ModelSettings, Runner +from agents.run import RunConfig +from agents.sandbox import Manifest, SandboxAgent, SandboxRunConfig +from agents.sandbox.capabilities import ( + Capabilities, + LocalDirLazySkillSource, + Skills, +) +from agents.sandbox.entries import LocalDir +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +EXAMPLE_DIR = Path(__file__).resolve().parent +HOST_REPO_DIR = EXAMPLE_DIR / "repo" +HOST_SKILLS_DIR = EXAMPLE_DIR / "skills" +TARGET_TEST_CMD = "sh tests/test_credit_note.sh" + + +def build_agent(model: str) -> SandboxAgent[None]: + return SandboxAgent( + name="Sandbox engineer", + model=model, + instructions=( + "Inspect the repo, make the smallest correct change, run the most relevant checks, " + "and summarize the file changes and risks.

It uses a tiny shell-based repo so the example can be verified deterministically across Unix-local runs. Your real task repo can of course be Python, JavaScript, or anything else. + +## Common patterns + +Start from the full example above. In many cases, the same `SandboxAgent` can stay intact while only the sandbox client, sandbox-session source, or workspace source changes. + +### Switch sandbox clients + +Keep the agent definition the same and change only the run config. Use Docker when you want container isolation or image parity, or a hosted provider when you want provider-managed execution. See [Sandbox clients](clients.md) for examples and provider options. + +### Override the workspace + +Keep the agent definition the same and swap only the fresh-session manifest: + +```python +from agents.run import RunConfig +from agents.sandbox import Manifest, SandboxRunConfig +from agents.sandbox.entries import GitRepo +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +run_config = RunConfig( + sandbox=SandboxRunConfig( + client=UnixLocalSandboxClient(), + manifest=Manifest( + entries={ + "repo": GitRepo(repo="openai/openai-agents-python", ref="main"), + } + ), + ), +) +``` + +Use this when the same agent role should run against different repos, packets, or task bundles without rebuilding the agent. The validated coding example above shows the same pattern with `default_manifest` instead of a one-off override. + +### Inject a sandbox session + +Inject a live sandbox session when you need explicit lifecycle control, post-run inspection, or output copying: + +```python +from agents import Runner +from agents.run import RunConfig +from agents.sandbox import SandboxRunConfig +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +client = UnixLocalSandboxClient() +sandbox = await client.create(manifest=agent.default_manifest) + +async with sandbox: + result = await Runner.run( + agent, + prompt, + run_config=RunConfig( + sandbox=SandboxRunConfig(session=sandbox), + ), + ) +``` + +Use this when you want to inspect the workspace after the run or stream over an already-started sandbox session. See [examples/sandbox/docs/coding_task.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/docs/coding_task.py) and [examples/sandbox/docker/docker_runner.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/docker/docker_runner.py). + +### Resume from session state + +If you already serialized sandbox state outside `RunState`, let the runner reconnect from that state: + +```python +from agents.run import RunConfig +from agents.sandbox import SandboxRunConfig + +serialized = load_saved_payload() +restored_state = client.deserialize_session_state(serialized) + +run_config = RunConfig( + sandbox=SandboxRunConfig( + client=client, + session_state=restored_state, + ), +) +``` + +Use this when sandbox state lives in your own storage or job system and you want `Runner` to resume from it directly. See [examples/sandbox/extensions/blaxel_runner.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/extensions/blaxel_runner.py) for the serialize/deserialize flow. + +### Start from a snapshot + +Seed a new sandbox from saved files and artifacts: + +```python +from pathlib import Path + +from agents.run import RunConfig +from agents.sandbox import LocalSnapshotSpec, SandboxRunConfig +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +run_config = RunConfig( + sandbox=SandboxRunConfig( + client=UnixLocalSandboxClient(), + snapshot=LocalSnapshotSpec(base_path=Path("/tmp/my-sandbox-snapshot")), + ), +) +``` + +Use this when a fresh run should start from saved workspace contents rather than only `agent.default_manifest`. See [examples/sandbox/memory.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/memory.py) for a local snapshot flow and [examples/sandbox/sandbox_agent_with_remote_snapshot.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/sandbox_agent_with_remote_snapshot.py) for a remote snapshot client. + +### Load skills from Git + +Swap the local skill source for a repository-backed one: + +```python +from agents.sandbox.capabilities import Capabilities, Skills +from agents.sandbox.entries import GitRepo + +capabilities = Capabilities.default() + [ + Skills(from_=GitRepo(repo="sdcoffey/tax-prep-skills", ref="main")), +] +``` + +Use this when the skills bundle has its own release cadence or should be shared across sandboxes. See [examples/sandbox/tax_prep.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/tax_prep.py). + +### Expose as tools + +Tool-agents can either get their own sandbox boundary or reuse a live sandbox from the parent run. Reuse is useful for a fast read-only explorer agent: it can inspect the exact workspace the parent is using without paying to create, hydrate, or snapshot another sandbox. + +```python +from agents import Runner +from agents.run import RunConfig +from agents.sandbox import FileMode, Manifest, Permissions, SandboxAgent, SandboxRunConfig, User +from agents.sandbox.entries import Dir, File +from agents.sandbox.sandboxes.unix_local import UnixLocalSandboxClient + +coordinator = User(name="coordinator") +explorer = User(name="explorer") + +manifest = Manifest( + users=[coordinator, explorer], + entries={ + "pricing_packet": Dir( + group=coordinator, + permissions=Permissions( + owner=FileMode.ALL, + group=FileMode.ALL, + other=FileMode.READ | FileMode.EXEC, + directory=True, + ), + children={ + "pricing.md": File( + content=b"Pricing packet contents...", + group=coordinator, + permissions=Permissions( + owner=FileMode.ALL, + group=FileMode.ALL, + other=FileMode.READ, + ), + ), + }, + ), + "work": Dir( + group=coordinator, + permissions=Permissions( + owner=FileMode.ALL, + group=FileMode.ALL, + other=FileMode.NONE, + directory=True, + ), + ), + }, +) + +pricing_explorer = SandboxAgent( + name="Pricing Explorer", + instructions="Read `pricing_packet/` and summarize commercial risk.

The `pricing_packet/` entries are readable by `other` users, so the explorer can inspect them quickly, but it does not have write bits. The `work/` directory is only available to the coordinator's user/group, so the parent can write the final artifact while the explorer stays read-only. + +When a tool-agent needs real isolation instead, give it its own sandbox `RunConfig`: + +```python +from docker import from_env as docker_from_env + +from agents.run import RunConfig +from agents.sandbox import SandboxRunConfig +from agents.sandbox.sandboxes.docker import DockerSandboxClient, DockerSandboxClientOptions + +rollout_agent.as_tool( + tool_name="review_rollout_risk", + tool_description="Inspect the rollout packet and summarize implementation risk.", + run_config=RunConfig( + sandbox=SandboxRunConfig( + client=DockerSandboxClient(docker_from_env()), + options=DockerSandboxClientOptions(image="python:3.14-slim"), + ), + ), +) +``` + +Use a separate sandbox when the tool-agent should mutate freely, run untrusted commands, or use a different backend/image. See [examples/sandbox/sandbox_agents_as_tools.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/sandbox_agents_as_tools.py). + +### Combine with local tools and MCP + +Keep the sandbox workspace while still using ordinary tools on the same agent: + +```python +from agents.sandbox import SandboxAgent +from agents.sandbox.capabilities import Shell + +agent = SandboxAgent( + name="Workspace reviewer", + instructions="Inspect the workspace and call host tools when needed.", + tools=[get_discount_approval_path], + mcp_servers=[server], + capabilities=[Shell()], +) +``` + +Use this when workspace inspection is only one part of the agent's job. See [examples/sandbox/sandbox_agent_with_tools.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/sandbox_agent_with_tools.py). + +## Memory + +Use the `Memory` capability when future sandbox-agent runs should learn from prior runs.

The active agent changes, but the run does not become nested. If a non-sandbox intake agent hands off to a sandbox reviewer, the next model call in that same run is prepared for the sandbox agent, and that sandbox agent becomes the one taking the next turn. In other words, handoffs change which agent owns the next turn of the same run. See [examples/sandbox/handoffs.py](https://github.com/openai/openai-agents-python/blob/main/examples/sandbox/handoffs.py). + +With `Agent.as_tool(...)`, the relationship is different. The outer orchestrator uses one outer turn to decide to call the tool, and that tool call starts a nested run for the sandbox agent. The nested run has its own turn loop, `max_turns`, approvals, and usually its own sandbox `RunConfig`. It may finish in one nested turn or take several. From the outer orchestrator's point of view, all of that work still sits behind one tool invocation, so the nested turns do not increment the outer run's turn counter.

When live memory update is enabled (by default), it also requires `Filesystem()`, which lets the agent update `memories/MEMORY.md` if the agent discovers stale memory or the user asks it to update memory. + +By default, memory artifacts are stored in the sandbox workspace under `memories/`. To reuse them in a later run, preserve and reuse the whole configured memories directory by keeping the same live sandbox session or resuming from a persisted session state or snapshot; a fresh empty sandbox starts with empty memory. + +`Memory()` enables both reading and generating memories. Use `Memory(generate=None)` for agents that should read memory but should not generate new memories: for example, an internal agent, subagent, checker, or one-off tool agent whose run doesn't add much signal. Use `Memory(read=None)` when the run should generate memory for later, but the user doesn't want the run to be influenced by existing memory. + +## Read memory + +Memory reads use progressive disclosure. At the start of a run, the SDK injects a small summary (`memory_summary.md`) of generally useful tips, user preferences, and available memories into the agent's developer prompt.

It opens the corresponding prior rollout summaries under the configured `rollout_summaries/` directory only when the task needs more detail. + +Memory can become stale. Agents are instructed to treat memories as guidance only and trust the current environment. By default, memory reads have `live_update` enabled, so if the agent discovers stale memory, it can update the configured `MEMORY.md` in the same run. Disable live updates when the agent should read memory but not modify it during the run, for example if the run is latency sensitive. + +## Generate memory + +After a run finishes, the sandbox runtime appends that run segment to a conversation file.

A memory-generating model processes one accumulated conversation file and generates a conversation summary. System, developer, and reasoning content are omitted. If the conversation is too long, it is truncated to fit within the context window, with the beginning and end preserved. It also generates a raw memory extract: compact notes from the conversation that Phase 2 can consolidate. +2. Phase 2: layout consolidation. A consolidation agent reads raw memories for one memory layout, opens conversation summaries when more evidence is needed, and extracts patterns into `MEMORY.md` and `memory_summary.md`. + +The default workspace layout is: + +```text +workspace/ +├── sessions/ +│ └── .jsonl +└── memories/ + ├── memory_summary.md + ├── MEMORY.md + ├── raw_memories.md (intermediate) + ├── phase_two_selection.json (intermediate) + ├── raw_memories/ (intermediate) + │ └── .md + ├── rollout_summaries/ + │ └── _.md + └── skills/ +``` + +You can configure memory generation with `MemoryGenerateConfig`: + +```python +from agents.sandbox import MemoryGenerateConfig +from agents.sandbox.capabilities import Memory + +memory = Memory( + generate=MemoryGenerateConfig( + max_raw_memories_for_consolidation=128, + extra_prompt="Pay extra attention to what made the customer more satisfied or annoyed", + ), +) +``` + +Use `extra_prompt` to tell the memory generator which signals matter most for your use case, such as customer and company details for a GTM agent. + +If recent raw memories exceed `max_raw_memories_for_consolidation` (defaults to 256), Phase 2 keeps only memories from the newest conversations and removes older ones. Recency is based on the last time the conversation is updated. This forgetting mechanism helps memories reflect the newest environment. + +## Multi-turn conversations + +For multi-turn sandbox chats, use the normal SDK `Session` together with the same live sandbox session: + +```python +from agents import Runner, SQLiteSession +from agents.run import RunConfig +from agents.sandbox import SandboxRunConfig + +conversation_session = SQLiteSession("gtm-q2-pipeline-review") +sandbox = await client.create(manifest=agent.default_manifest) + +async with sandbox: + run_config = RunConfig( + sandbox=SandboxRunConfig(session=sandbox), + workflow_name="GTM memory example", + ) + await Runner.run( + agent, + "Analyze data/leads.csv and identify one promising GTM segment.", + session=conversation_session, + run_config=run_config, + ) + await Runner.run( + agent, + "Using that analysis, write a short outreach hypothesis.", + session=conversation_session, + run_config=run_config, + ) +``` + +Both runs append to one memory conversation file because they pass the same SDK conversation session (`session=conversation_session`) and therefore share the same `session.session_id`. This is different from the sandbox (`sandbox`), which identifies the live workspace and is not used as the memory conversation ID. Phase 1 sees the accumulated conversation when the sandbox session closes, so it can extract memory from the whole exchange instead of two isolated turns. + +If you want multiple `Runner.run(...)` calls to become one memory conversation, pass a stable identifier across those calls.

For example, the change may be the result of a continuation, revision, and/or adjustment to completed project. + +**Official definition:** Description (and corresponding code) that provides information on any changes made to the Federal prime award. There are typically multiple actions for each award. + +(Note: This definition encompasses current data elements ‘Type of Action’ for financial assistance and ‘Reason for Modification’ for procurement) + +## Agency + +On this website, we use the term agency to mean any federal department, commission, or other U.S. government entity. Agencies can have multiple sub-agencies. For example, the National Park Service is a sub-agency of the U.S. Department of the Interior. + +## Agency Identifier + +Identifies the agency responsible for a Treasury account. This is a 3-digit number that is a part of a Treasury Account Symbol (TAS). + +**Official definition:** The agency code identifies the department or agency that is responsible for the account. + +## Allocation Transfer Agency (ATA) Identifier + +Identifies an agency that receives funds through an allocation (non-expenditure) transfer. This is a 3-digit number that is a part of a Treasury Account Symbol (TAS). + +**Official definition:** The allocation agency identifies the department or agency that is receiving funds through an allocation (non-expenditure) transfer. + +## Appropriation + +The process by which Congress designates and approves spending for a specific purpose (e.g., a project or program). Most government spending is determined through appropriation bills each year. These bills must be passed by Congress and signed by the President. + +When an appropriation is not passed by Congress before the beginning of the fiscal year, a “continuing resolution” (often referred to as a “CR”) may be enacted to avoid a government shutdown. A CR is a law that provides stopgap funding for agencies until their regular appropriations are passed. + +## Appropriation Account + +When Congress passes a law, it often gives an agency authority to carry out a project. When this happens, Congress may set aside money for the project. An appropriation account tracks the money, much like a bank account. The appropriation account number (like a bank account number) is called a Treasury Account Symbol (TAS). + +**Official definition:** The basic unit of an appropriation generally reflecting each unnumbered paragraph in an appropriation act. An appropriation account typically encompasses a number of activities or projects and may be subject to restrictions or conditions applicable to only the account, the appropriation act, titles within an appropriation act, other appropriation acts, or the Government as a whole. + +An appropriations account is represented by a TAFS created by Treasury in consultation with OMB. + +(defined in OMB Circular A-11) + +## Assistance Listings (CFDA Program) + +Assistance Listings, previously known as "CFDA programs", provide a full listing of federal programs that are available to organizations, government agencies (state, local, tribal), U.S. territories, and individuals who are authorized to do business with the government. An Assistance Listing program can be a project, service, or activity. Each program has a unique, 5-digit number in the form of XX.XXX. The first two digits represent the funding agency. The last three digits represent the program. + +Examples of Assistance Listings include: + +* Social Security Retirement Insurance (96.002) +* Medicare Supplementary Medical Insurance (93.774) +* Supplemental Nutrition Assistance Program (10.551) +* Highway Planning and Construction (20.205) +* National School Lunch Program (10.555) + +**Official definition:** The number assigned to an Assistance Listing in the Catalog of Federal Domestic Assistance (CFDA) and SAM.gov. + +The title of the Assistance Listing under which the Federal award was funded in the Catalog of Federal Domestic Assistance (CFDA) and SAM.gov. + +## Availability Type Code + +Within a Treasury Account Symbol (TAS), this one-letter code Identifies the availability (or time period) for obligations to be made on the appropriation account. A TAS will have an “X” if there is an unlimited or indefinite period to incur new obligations. + +**Official definition:** In appropriations accounts, the availability type code identifies an unlimited period to incur new obligations; this is denoted by the letter X. + +## Award + +Money the federal government has promised to pay a recipient. Funding may be awarded to a company, organization, government entity (i.e., state, local, tribal, federal, or foreign), or individual. It may be obligated (promised) in the form of a contract, grant, loan, insurance, direct payment, etc. + +## Award Amount + +The amount that the federal government has promised to pay (obligated) a recipient, because it has signed a contract, awarded a grant, etc. + +**Official definition:** The cumulative amount obligated by the Federal Government for an award, which is calculated by USAspending.gov. + +For procurement and financial assistance awards except loans, this is the sum of Federal Action Obligations. + +For loans or loan guarantees, this is the Original Subsidy Cost. + +## Award ID + +A unique identification number for each individual award. + +**Official definition:** The unique identifier of the specific award being reported, i.e. Federal Award Identification Number (FAIN) for financial assistance and Procurement Instrument Identifier (PIID) for procurement. + +## Award Type + +The federal government can distribute funding in several forms, including contracts, grants, loans, insurance, and direct payments. Award Type is a classification that provides more information about the structure of the award. Examples include: + +- Purchase Order (a type of contract) +- Definitive Contract (a type of contract) +- Block Grant (a type of grant) +- Direct Loan (a type of loan) + +**Official definition:** Description (and corresponding code) that provides information to distinguish type of contract, grant, or loan and providers the user with more granularity into the method of delivery of the outcomes. + +## Awarding Agency + +The Awarding Agency is the agency that issues and administers the award. This agency usually pays for the funding out of its own budget. In some cases, the money is financed by another agency, called the Funding Agency. + +**Official definition:** The name and code associated with a department or establishment of the Government as used in the Treasury Account Fund Symbol (TAFS). + +## Awarding Office + +The office within an agency that issues and administers the award. + +**Official definition:** Name and identifier of the level n organization that awarded, executed or is otherwise responsible for the transaction. + +## Awarding Sub-Agency + +The Awarding Sub Agency is the sub agency that issues and administers the award. For example, the Internal Revenue Service (IRS) is a sub agency of the Department of the Treasury. + +**Official definition:** Name and identifier of the level 2 organization that awarded, executed or is otherwise responsible for the transaction. + +## Awards Data (File D) + +Awards Data is ingested up to daily from government-wide systems where agencies submit financial assistance and procurement data. Because it comprises two separate datasets, it is sometimes referred to as Procurement Data (File D1) and Assistance Data (File D2). Awards Data is separate from the financial data submissions that agencies publish to USAspending.gov each month or quarter (the submissions that include Files A, B, and C). Data from File D1/D2 supplements award data found in Account Breakdown by Award (File C) to provide a full picture of award spending. +When you see a reference to File D on the site, it refers to the up-to-date set of all agencies’ procurement (File D1) and assistance (File D2) datasets and not one specific agency’s files. + +## Balance Brought Forward + +Funds that were not spent (obligated or outlaid) in previous years and are authorized to be spent in the current year. + +**Official definition:** The definition for this element appears in Appendix F of OMB Circular A-11 issued June 2015; a brief summary from A-11 appears below. For unexpired accounts: Amount of unobligated balance of appropriations or other budgetary resources carried forward from the preceding year and available for obligation without new action by Congress. For expired accounts: Amount of expired unobligated balances available for upward adjustments of obligations. + +## Base Transaction Action Date + +The action date of the original Prime Award Transaction of a Prime Award Summary. Note that this date may be different from the Period of Performance Start Date. Because award obligations are tied to action dates, any search for spending data on USAspending will search by this data element rather than by Period of Performance dates. + +## Base Transaction Description + +A brief description of the purpose of the award. + +**Official definition:** For procurement awards: Per the FPDS data dictionary, a brief, summary level, plain English, description of the contract, award, or modification. Additional information: the description field may also include abbreviations, acronyms, or other information that is not plain English such as that required by OMB policies (CARES Act, etc). + +For financial assistance awards: A plain language description of the Federal award purpose; activities to be performed; deliverables and expected outcomes; intended beneficiary(ies); and subrecipient activities if known/specified at the time of award. + +## Basic Ordering Agreement (BOA) + +A Basic Ordering Agreement (BOA) is a type of Indefinite Delivery Vehicle (IDV). It is not a contract; it is a written understanding between government and contractor. It details the supplies or services offered. It also details pricing and delivery for future orders. + +BOA's can speed up contracting when requirements are uncertain. For instance, when specifications, quantities, and prices are not yet known. + +These agreements can also help the government achieve economies of scale for part orders. For the contractor, they can lessen lead-time, enable a larger inventory investment, and lessen old inventory. + +## Beginning Period of Availability + +Identifies the first year that an appropriation account may incur new obligations. This is for annual and multi-year funds only. This is a 4-digit number representing the year (e.g., 2017). It is a part of a Treasury Account Symbol (TAS). + +**Official definition:** In annual and multi-year funds, the beginning period of availability identifies the first year of availability under law that an appropriation account may incur new obligations. + +## Blanket Purchase Agreement (BPA) + +A Blanket Purchase Agreement (BPA) is a method federal agencies use to make repeat purchases of supplies or services. A type of Indefinite Delivery Vehicle (IDV), a BPA operates by setting up a "charge account" with trusted vendors. Both agencies and vendors often prefer BPAs because they help speed up the process of repeated purchases. Once a BPA is set up, repeat purchases are easy for both sides. + +A BPA is an agreement with an individual agency, meaning only a handful of offices can place orders on a BPA. A BPA can be awarded to a set of vendors, who will then be able to bid on upcoming orders. A BPA can be set up with or without General Services Administration (GSA) schedules. Without GSA schedules, orders are capped at the Simplified Acquisition Threshold (SAT) of $100,000. + +Examples of BPAs: + +- Agency A establishes a BPA with a computer manufacturer for repeat laptop purchases +- Agency B establishes a BPA with a graphic design agency for design of brochures and event signage + +## Block Grant + +Block grants are awarded by the federal government to state and local governments for broadly defined purposes — for example, social services or community development. + +**Official definition:** Block grants are given primarily to general purpose governmental units in accordance with a statutory formula. Such grants can be used for a variety of activities within a broad functional area. Examples of federal block grant programs are the Omnibus Crime Control and Safe Streets Act of 1968, the Housing and Community Development Act of 1974, and the grants to states for social services under title XX of the Social Security Act. + +## Budget Authority + +A federal agency is only allowed to spend money if Congress provides the authority by law for that spending. That permission to spend is called “budget authority.” + +Budget authority can be granted through an appropriation law, which specifies a purpose, usually a maximum amount of money, and a set time period. Budget authority can also be granted for spending unused funds from a previous year, or to spend money that the agency takes in (e.g., the National Park Service is authorized to spend fees collected for park admission regardless of the amount). + +**Official definition:** The total amount of all obligation budget authority including unobligated balances carried forward, adjustments to unobligated balances carried forward, appropriated amounts, and other budgetary resources, as of the reported date. + +## Budget Authority Appropriated + +A provision of law (not necessarily in an appropriations act) authorizing an account to incur obligations and to make outlays for a given purpose. Usually, but not always, an appropriation provides budget authority. + +(defined in OMB Circular A-11) + +## Budget Function + +The federal budget is divided into approximately 20 categories, known as budget functions. These categories organize federal spending into topics based on the major purpose the spending serves (e.g., National Defense, Transportation, Health). + +These are further broken down into budget sub functions. + +## Budget Sub-Function + +The federal budget is divided into functions and sub functions. These categories organize federal spending into topics based on the major purpose the spending serves. There are about 20 major functions (e.g., National Defense, Transportation, Health). Most of these functions are further divided into sub functions. + +For example, the budget function for Health is divided into sub functions for Health care services, Health research and training, and Consumer and occupational health and safety. + +## Budgetary Resources + +Budgetary resources mean amounts available to incur obligations in a given year. Budgetary resources consist of new budget authority (from appropriations, borrowing authority, contract authority, or offsetting collections) and unobligated balances of budget authority provided in previous years. On this website, budgetary resources do not include financing accounts, which are a type of treasury account used to finance federal loans and are not considered spending per Office of Management and Budget (OMB) policy. For the purposes of USASpending.gov, “funding” represents “budgetary resources”. + +Budgetary resources include financial transfers between Government accounts. Financial transfers are financial interchanges between Federal Government accounts that are not an exchange for goods and services. For example, an expenditure transfer that shifts budgetary resources between a General Fund account, (e.g., Payment to Highway Trust Fund) and a trust fund (e.g., Highway Trust Fund) is considered a financial transfer. For financial transfers, budgetary resources are shown in both accounts. + +## Clinger-Cohen Act + +The Clinger-Cohen Act (CCA) of 1996 is a federal law designed to improve the way the federal government acquires, uses, and disposes of IT. It strives to make IT purchases more strategic. + +**Official definition:** A code indicating the funding office has certified that the information technology purchase meets the planning requirements in 40 USC 11312 and 40 USC 11313. + +## Construction Wage Rate Requirements + +Indicates whether the transaction is subject to the Construction Wage Rate Requirements. The clause is 52.222-6 "Construction Wage Rate Requirements" -that goes with Wage Rate Requirements (Construction) (formerly Davis-Bacon Act). + +## Contract + +An agreement between the federal government and a prime recipient to provide goods and services for a fee. + +**Official definition:** Contract means a mutually binding legal relationship obligating the seller to furnish the supplies or services (including construction) and the buyer to pay for them. It includes all types of commitments that obligate the government to an expenditure of appropriated funds and that, except as otherwise authorized, are in writing. In addition to bilateral instruments, contracts include (but are not limited to) awards and notices of awards; job orders or task letters issued under basic ordering agreements; letter contracts; orders, such as purchase orders, under which the contract becomes effective by written acceptance or performance; and bilateral contract modifications. Contracts do not include grants and cooperative agreements covered by 31 U.S.C. 6301, et seq. + +## Contract Pricing Type + +Payment model for a contract. Each has a different way of accounting for costs, fees, and profits. Contract pricing types include: + +- Fixed Price Redetermination +- Fixed Price Level of Effort +- Firm Fixed Price +- Fixed Price with Economic Price Adjustment +- Fixed Price Incentive +- Fixed Price Award Fee +- Cost Plus Award Fee +- Cost No Fee +- Cost Sharing +- Cost Plus +- Fixed Fee +- Cost Plus Incentive Fee +- Time and Materials +- Labor Hours + +**Official definition:** The type of contract as defined in FAR Part 16 that applies to this procurement. + +## Contractor + +A business, organization, or agency that receives funding and/or performs work on a contract. A contractor may be a corporation, small business, university, non-profit, sole proprietor, or other entity. When a company has a contract with the U.S. government, they may hire another company to perform part of the work. When this happens, the company who received the award is called the prime contractor. The company hired by the prime is called the sub-contractor. + +## Contractual Services and Supplies + +This major object class includes services or supplies purchased to support the fulfillment of government activities during a specified contract period. Some examples include transportation of government personnel and supplies, rent and other utilities, rental payments made to GSA, printing and reproduction costs, and operations/maintenance costs for federal facilities. + +These items are not equivalent to the Federal Acquisition Regulation (FAR) federal contract award spending and will not match total contract award spending on USAspending.gov. + +**Official definition:** This major object class covers purchases of contractual services and supplies in object classes 21.0 through 26.0, including: +21.0 Travel and transportation of persons +22.0 Transportation of things, Rent, Communications, and Utilities +23 Rent, Communications, and Utilities +23.1 Rental payments to GSA +23.2 Rental payments to others +23.3 Communications, utilities, and miscellaneous charges +24.0 Printing and reproduction +25 Other contractual services +25.1 Advisory and assistance services +25.2 Other services from non-Federal sources +25.3 Other goods and services from Federal sources +25.4 Operation and maintenance of facilities +25.5 Research and development contracts +25.6 Medical care +25.7 Operation and maintenance of equipment +25.8 Subsistence and support of persons +26.0 Supplies and materials + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Cooperative Agreement + +Grant awarded to provide assistance. It is characterized by extended involvement between recipient and agency. It requires substantial oversight by the agency, and includes reporting requirements. + +## Current Award Amount + +The amount of money that the government has promised (obligated) to pay a recipient for a contract. This means the base amount and any exercised options. + +**Official definition:** For procurement, the total amount obligated to date on a contract, including the base and exercised options. + +## Definitive Contract + +A Definitive Contract is a mutually binding legal relationship obligating the seller to provide the supplies or services (including construction) and the buyer to pay for them. It includes all types of commitments that obligate the Government to an expenditure of appropriated funds and that, except as otherwise authorized, are in writing. In addition to bilateral instruments, contracts include (but are not limited to) awards and notices of awards; job orders, or task letters, issued under basic ordering agreements; letter contracts; orders, such as purchase orders, under which the contract becomes effective by written acceptance or performance; and bilateral contract modifications. + +## Delivery Order Contract + +An Indefinite Quantity Contract for supplies (not services) is sometimes referred to as a Delivery Order Contract. With this type of contract, the government promises to buy supplies over a period of time from a vendor. Instead of an exact amount, it sets a quantity range with a minimum and maximum. + +## Deobligation + +The cancellation or downward adjustment of previously obligated funds. Agencies deobligate funds to decrease the amount available under an award. Deobligated funds may be reobligated within the period of availability of the appropriation. + +## Direct Loan + +Direct loan means a disbursement of funds by the Government to a non-Federal borrower under a contract that requires the repayment of such funds with or without interest. The term also includes certain equivalent transactions that extend credit. + +## Direct Payment + +A cash payment made by the federal government to an individual, a private firm, or another private institution. + +## Direct Payment for Specified Use + +Financial assistance provided by the federal government directly to individuals, private firms, and other private institutions for a particular activity. To receive this assistance, the recipient must perform certain agreed-upon activities and meet certain milestones. Direct payments don’t include solicited contracts for the procurement of goods and services for the government. + +**Official definition:** Includes financial assistance from the Federal government provided directly to individuals, private firms, and other private institutions to encourage or subsidize a particular activity by conditioning the receipt of the assistance on a particular performance by the recipient. + +## Direct Payment with Unrestricted Use + +Financial assistance provided by the federal government directly to beneficiaries who meet certain federal eligibility requirements. This type of assistance doesn’t place any restrictions on how the recipient spends the money. Some examples of direct payments include retirement, pension, and compensatory programs. + +## Disaster Emergency Fund Code (DEFC) + +Disaster Emergency Fund Code (DEFC) is used to track the spending of funding for disasters and emergencies such as COVID-19. Each code links to one or more legislative bills that authorized the funding. + +**Official definition:** The Office of Management and Budget (OMB), working with the Department of Treasury’s Fiscal Service, has identified a Government-wide Treasury Account Symbol Adjusted Trial Balance System (GTAS) attribute called ‘Disaster Emergency Fund Code (DEFC)’ to track appropriations classified as disaster or emergency. This code applies to the budgetary resources, obligations incurred, unobligated and obligated balances, and outlays that result from these appropriations. + + +As established in Memorandum M-18-08, the domain value set for DEFC is a single letter from ‘A’ to ‘Z’. The default domain value for all funding without disaster or emergency designation is ‘Q’. OMB assigns a new DEFC domain value from the set to each enacted appropriation with disaster or emergency funding. The corresponding domain title for each DEFC domain value identifies the associated public law number(s) and whether the funding is disaster or emergency. + + +Memorandum M-20-21 amended the above to allow agencies to use DEFC to meet reporting requirements for COVID-19 supplemental funding, which required tracking of funds not designated as emergency. + + +Agencies use the following DEFC domain values and titles for COVID-19 supplemental funding: + +- **DEFC ‘L’** Public Law 116-123, designated as emergency +- **DEFC ‘M’** Public Law 116-127, designated as emergency +- **DEFC ‘N’** Public Law 116-136, designated as emergency +- **DEFC ‘O’** Public Law 116-136, Public Law 116-139, and Public Law 116-260, not designated as emergency +- **DEFC ‘P’** Public Law 116-139, designated as emergency +- **DEFC ‘U’** Public Law 116-260, designated as emergency +- **DEFC ‘V’** Public Law 117-2, American Rescue Plan Act of 2021, not designated as emergency + + +Note that the National Interest Action (NIA) code is also used to track COVID-19 spending. However, it only applies to procurement actions (i.e., contracts) and is not necessarily tied to COVID-19 supplemental appropriations. Thus, awards with the COVID-19 NIA value may not have a COVID-19 DEFC value, and vice versa. + +## DOD Claimant Program Code + +Department of Defense (DOD) code that designates a grouping of supplies, construction, or other services. Each code has letters and numbers. + +**Official definition:** A claimant program number designates a grouping of supplies, construction, or other services. + +## DUNS + +DUNS stands for Data Universal Numbering System. It is a unique 9-digit identification number assigned to a company or organization by Dun & Bradstreet, Inc. A DUNS is required to register in the System for Award Management (SAM). An organization must be registered in SAM (and obtain a DUNS) to do business with the federal government. There is a separate DUNS number for each business location in the Dun & Bradstreet database. The DUNS number is random, and specific digits have no significance. + +**Official definition:** The unique identification number for an awardee or recipient. Currently the identifier is the 9-digit number assigned by Dun & Bradstreet referred to as the DUNS® number. + +## Ending Period of Availability + +Identifies the last year that an appropriation account may incur new obligations. This is for annual and multi-year funds only. This is a 4-digit number representing the year (e.g., 2018). It is a part of a Treasury Account Symbol (TAS). + +**Official definition:** In annual and multi-year funds, the end period of availability identifies the last year of funds availability under law that an appropriation account may incur new obligations. + +## Extent Competed + +A code that represents the competitive nature of the contract. Values include: + +- A = Full and open competition (competitive proposal, no sources excluded) +- B = Not available for competition +- C = Not competed +- D = Full and open competition after exclusion of sources +- E = Follow-on to competed action (a follow-on to an existing competed contract) +- F = Competed under Simplified Acquisition Threshold (SAP) +- G = Not competed under Simplified Acquisition Threshold (SAP) + +**Official definition:** A code that represents the competitive nature of the contract. +[Read the Federal Procurement Data System definition](https://www.fpds.gov/help/Extent_Competed.htm). + +## Face Value of Loan + +Face value of a loan is the total amount of the loan, and the amount that agencies have directly issued (for direct loans) or facilitated by compensating the lender if the borrower defaults (for loan guarantees). + +Since loans are expected to be paid back, in budgetary terms, the face value of a loan is not considered spending and is not included in any obligation or outlay figure. However, because not all loans are repaid, they do have costs to the government. The government’s calculation of these costs is called subsidy cost. + +**Official definition:** The face value of the direct loan or loan guarantee. + +## FAIN + +An identification code assigned to a specific financial assistance award by an agency for tracking purposes. The FAIN is tied to that award (and all future modifications to that award) throughout the award's life. Within an agency, FAINs are unique; a new award must be issued a new FAIN. FAIN stands for Federal Award Identification Number, though the digits may be both letters and numbers. + +**Official definition:** The Federal Award Identification Number (FAIN) is the unique ID within the Federal agency for each financial assistance award. + +## Federal Account + +Federal Accounts refer to the set of Treasury spending accounts that are grouped under a given "Federal Account Symbol." On this website we group them by their agency identifier (3-digit code) and Main Account code (4-digit code). + +## Federal Action Obligation + +Amount of Federal Government’s obligation, de-obligation, or liability, in dollars, for an award transaction. + +## Federal Supply Schedule (FSS) + +The Federal Supply Schedule (FSS) is a listing of contractors that have been awarded a contract by GSA that can be used by all federal agencies. This is also known as a Multiple Award Schedule (MAS). + +## Financial Assistance + +A federal program, service, or activity that directly aids organizations, individuals, or state/local/tribal governments. Sectors include education, health, public safety and public welfare - to name a few. Financial assistance is distributed in many forms, including grants, loans, direct payments, or insurance. + +## Fiscal Year (FY) + +The fiscal year is an accounting period that spans 12 months. For the federal government, it runs from October 1 to September 30. For example, Fiscal Year 2017 (FY 2017) starts October 1, 2016 and ends September 30, 2017. +A fiscal year may be broken down into quarters. For the federal government, these quarters are: + +- Q1: October - December +- Q2: January - March +- Q3: April - June +- Q4: July - September + +## Formula Grant + +An allocation made to states (or their subdivisions, which include county and local governments, among other entities) according to law. These grants are awarded for continuing activities that aren’t confined to a specific project — for example, Medicaid. + +**Official definition:** Allocations made to states (or their subdivisions) according to law or administrative regulation. These grants are awarded for continuing activities that aren’t confined to a specific project. + +## Funding Agency + +A Funding Agency pays for the majority of funds for an award out of its budget. Typically, the Funding Agency is the same as the Awarding Agency. In some cases, one agency will administer an award (Awarding Agency) and another agency will pay for it (Funding Agency). + +**Official definition:** Name and 3-digit CGAC agency code of the department or establishment of the Government that provided the preponderance of the funds for an award and/or individual transactions related to an award. + +## Funding Obligated + +The amount of money that an agency has promised to pay, usually because the agency has signed a contract, awarded a grant, or placed an order for goods or services. + +In the "Financial Systems Details" tab on an award summary page, this amount refers to the funding obligated in an agency's financial system. + +**Official definition:** The definition for this element appears in Section 20 of OMB Circular A-11 issued June 2015; a brief summary from A-11 appears below. + +Obligation means a binding agreement that will result in outlays, immediately or in the future. Budgetary resources must be available before obligations can be incurred legally. + +## Funding Office + +The office within an agency that pays the majority of funds for an award out of its budget. + +**Official definition:** Name and identifier of the level n organization that provided the preponderance of the funds obligated by this transaction. + +## Funding Opportunity Goals Text + +A brief summary of the intended outcomes associated with the notice of funding opportunity. + +## Funding Opportunity Number + +An alphanumeric identifier that a Federal agency assigns to its funding opportunity announcement as part of the Notice of Funding Opportunity posted on the OMB-designated government-wide web site (currently grants.gov) for finding and applying for Federal financial assistance. + +## Funding Sub-Agency + +A component of a larger department or agency that pays for the majority of funds for an award out of its budget. Also known as a sub-tier agency. For example, Bureau of Indian Affairs is a sub-agency of Department of Interior. + +**Official definition:** Name and identifier of the level 2 organization that provided the preponderance of the funds obligated by this transaction. + +## Government wide Acquisition Contract (GWAC) + +Government-Wide Acquisition Contract (GWAC) is a multi-agency contract. It offers Information Technology (IT) services to agencies across the government. It is an Indefinite Delivery Vehicle (IDV) for certain types of IT work: + +- Systems design +- Software engineering +- Information assurance +- Enterprise architecture + +Vendors compete for the initial contracts. Once selected, they are eligible to compete further for agency-specific tasks. + +## Governmentwide Spending Data Model (GSDM) + +The Governmentwide Spending Data Model (GSDM), formerly called the DATA Act Information Model Schema (DAIMS), is the authoritative source for the data elements that establish government-wide data standards for spending data and their subsequent publication for transparency. + +**Official definition:** The Governmentwide Spending Data Model (GSDM), formerly called the DATA Act Information Model Schema (DAIMS), was created as a result of the Digital Accountability and Transparency Act of 2014 (DATA Act). The GSDM is the authoritative source for the terms, definitions, formats and structures for hundreds of distinct data elements that establish government-wide data standards for spending data and their subsequent publication for transparency. + +The Office of Management and Budget (OMB) and Department of the Treasury (Treasury) collected public input and feedback from federal agencies and implemented an agile development methodology to create the DAIMS. The finalized DAIMS first published in April 2016. Since then, Treasury has periodically published updates to reflect the inclusion of legislation and policies that go beyond the DATA Act. + +In November 2023, DAIMS was rebranded as the GSDM to reflect the inclusion of new legislation and policies. The GSDM includes artifacts that provide technical guidance for federal agencies about what data to report to Treasury including the authoritative sources of the data elements and the submission format. The GSDM documents also provide data consumers with information and context to better understand the inherent complexity of the data. + +## Grant + +An award of financial assistance from a federal agency to a recipient to carry out a public project or service authorized by a United States law. Unlike loans, grants do not need to be repaid. Most grants are awarded to state and local governments. On this site, you’ll see reference to several types of grants, including block grants, formula grants, project grants, and cooperative agreements. + +**Official definition:** A federal financial assistance award making payment in cash or in kind for a specified purpose. The federal government is not expected to have substantial involvement with the state or local government or other recipient while the contemplated activity is being performed. The term “grant” is used broadly and may include a grant to nongovernmental recipients as well as one to a state or local government, while the term “grant-in-aid” is commonly used to refer only to a grant to a state or local government. (For a more detailed description, see the Federal Grant and Cooperative Agreement Act of 1977, 31 U.S.C. §§ 6301–6308.) The two major forms of federal grants-in-aid are block and categorical. + +## Grants and Fixed Charges + +This major object class includes grants, subsidies, and contributions to foreign countries; insurance claims; indemnities (for example, payments to veterans for death or disability, or to compensate for loss of property); interest and dividends; and refunds. + +**Official definition:** This major object class covers object classes 41.0 through 44.0. This includes: +41.0 Grants, subsidies, and +contributions +42.0 Insurance claims and +indemnities +43.0 Interest and dividends +44.0 Refunds + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Guaranteed / Insured Loans + +Loan guarantee means any guarantee, insurance, or other pledge with respect to the payment of all or a part of the principal or interest on any debt obligation of a non-Federal borrower to a non-Federal lender. The term does not include the insurance of deposits, shares, or other withdrawable accounts in financial institutions. + +## Highly Compensated Officer Name + +First Name: The first name of an individual identified as one of the five most highly compensated “Executives.” “Executive” means officers, managing partners, or any other employees in management positions. + +Middle Initial: The middle initial of an individual identified as one of the five most highly compensated “Executives.” “Executive” means officers, managing partners, or any other employees in management positions. + +Last Name: The last name of an individual identified as one of the five most highly compensated “Executives.” “Executive” means officers, managing partners, or any other employees in management positions. + +## Highly Compensated Officer Total Compensation + +The cash and noncash dollar value earned by the one of the five most highly compensated “Executives” during the awardee's preceding fiscal year and includes the following (for more information see 17 C.F.R. § 229.402(c)(2)): salary and bonuses, awards of stock, stock options, and stock appreciation rights, earnings for services under non-equity incentive plans, change in pension value, above-market earnings on deferred compensation which is not tax qualified, and other compensation. + +## Indefinite Delivery / Definite Quantity Contract + +An indefinite delivery contract (IDC) facilitates the delivery of supply and service orders during a set timeframe. This type of contract is awarded to one or more vendors. + +Definite Quantity Contracts, which are a type of IDC, provide for delivery of a definite quantity of supplies or services for a fixed period, with deliveries to be scheduled at designated locations upon order. + +## Indefinite Delivery / Indefinite Quantity (IDIQ) Contract + +An Indefinite Quantity Contract is a type of Indefinite Delivery Contract (IDC). Sometimes the government contracts to buy supplies or services from a vendor over a period of time. For instances that government does not know the exact quantity it will need, an Indefinite Quantity Contract sets a quantity range with a min and max. It does not specify an exact number. For services, this is often called a Task Order Contract. For supplies, this is often called a Delivery Order Contract. + +## Indefinite Delivery / Requirements Contract + +Requirements contracts are for the fulfillment of all purchase requirements of supplies or services for designated government activities during a specified contract period, with deliveries to be scheduled by placing orders with the contractor. + +## Indefinite Delivery Contract (IDC) + +Indefinite Delivery Contract (IDC) facilitates the delivery of supply and service orders during a set timeframe. This type of contract is awarded to one or more vendors. + +Types of IDC's Include: + +- Indefinite Delivery / Definite Quantity Contract +- Indefinite Delivery / Requirements Contract +- Indefinite Delivery / Indefinite Quantity (IDIQ) Contract + +## Indefinite Delivery Vehicle (IDV) + +Vehicle to facilitate the delivery of supply and service orders. IDV Types include: + +- Blanket Purchase Agreement (BPA) +- Basic Ordering Agreement (BOA) +- Government-Wide Acquisition Contract (GWAC) +- Multi-Agency Contract +- Indefinite Delivery Contract (IDC) +- Federal Supply Schedule (FSS) + +## Indirect Cost Federal Share Amount + +The total amount of any single Federal award action that is allocated, per the award recipient’s approved award budget, to indirect costs. + +## Insurance + +Financial assistance provided to assure reimbursement for losses sustained under specified conditions. Coverage may be provided directly by the Federal government or through private carriers and may or may not involve the payment of premiums. See Catalog for Federal Domestic Assistance (CFDA). + +## Labor Standards + +Indicates whether the transaction is subject to the Labor Standards. The clause for Labor Standards is 52.222-41 "Labor Standards" - that goes with the Service Contract Labor Standards (formerly Service Contract Act). + +## Latest Transaction Action Date + +The action date of the most recent Prime Award Transaction of a Prime Award Summary. Note that this date may be different from the Period of Performance End Date (Current or Potential). Because award obligations are tied to action dates, any search for spending data on USAspending will search by this data element rather than by Period of Performance dates. + +## Legal Entity Country Name and Code + +The Name and Code for the country in which the awardee or recipient is located, using the ISO 3166-1 Alpha-3 GENC Profile, and not the codes listed for those territories and possessions of the United States already identified as “states.” + +## Loan + +A federal award from the government that the borrower will eventually have to pay back. Direct loans are those made for a specific time period with a reasonable expectation of repayment; they may or may not require interest payments. Guaranteed loans require the federal government to pay the bank and take over the loan if the borrower defaults. + +## Loan Subsidy Cost + +When the government makes a direct loan or guarantees a loan, it expects the loan to be repaid. However, for any given loan program (e.g., student loans, small business loan guarantees) some individual loans are not repaid. Subsidy cost is the government’s way to estimate a loan’s likely cost to the government based on the size of the loan (i.e., its Face value), interest rate, the modeled risk of default in full or in part, and other factors. Subsidy cost is computed as a percentage of the loan value and does not include administrative costs. + +While the award amount for a grant or contract is the amount that the recipient gets, for a loan, the award amount is the subsidy cost. This is because the subsidy cost is the actual cost to the government (estimated). Loan Subsidy Cost has a direct budgetary impact and is factored into obligations and outlays when it is positive. Subsidy costs can be positive (indicating that the government is likely to lose money on the loan) or negative (indicating that the government is likely to make money on the loan). A positive Loan Subsidy Cost is usually smaller than the corresponding Face Value, but in certain edge cases it can be over 100% of the face value if the entire loan is written off and the government paid fees to a bank to issue the loan (which are also included in the subsidy cost). Administrative costs of running the loan or loan guarantee program itself are excluded from Loan Subsidy Cost calculation. + +**Official definition:** The estimated long-term cost to the Government of a direct loan or loan guarantee, or modification thereof, calculated on a net present value basis, excluding administrative costs. + +## Local Area Set Aside + +When awarding emergency response contracts during a major disaster or emergency declaration by the President, the government attempts to give preference to local firms. Preference may be given through a local area set-aside or an evaluation preference. + +**Official definition:** When awarding emergency response contracts during the term of a major disaster or emergency declaration by the President of the United States under the authority of the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. 5121, et seq.), preference shall be given, to the extent feasible and practicable, to local firms. Preference may be given through a local area set-aside or an evaluation preference. Note: When the value for the data element 'Multiple or Single Award IDV' is 'Single' on the Referenced IDV, the value for 'Local Area Set Aside' is propagated from the BPA. When the value is 'Multiple' user input is required. + +## Main Account Code + +This is a 4-digit number that is part of a Treasury Account Symbol (TAS) and Identifies the TAS type and purpose. It cannot be blank. + +**Official definition:** The main account code identifies the account in statute. + +## Materials, Supplies, Articles & Equip + +Indicates whether the transaction is subject to the Materials, Supplies, Articles, & Equip. The clause is 52.222-20 "Contracts for Materials, Supplies, Articles, and Equipment Exceeding $15,000" - that goes with Contracts for Materials, Supplies, Articles, and Equipment Exceeding $15,000 (formerly Walsh-Healey). + +## Modification Number + +The identifier of an action being reported that indicates the specific subsequent change to the initial award. + +## Multi-Agency Contract (MAC) + +A Multi-Agency Contract (MAC) is a task-order or delivery-order contract established by one agency for use by government agencies to obtain supplies and services. + +## Multiple Award Schedule (MAS) + +A listing of contractors that have been awarded a contract by GSA that can be used by all federal agencies. This is also known as a Federal Supply Schedule (FSS). + +## Multiple Recipients + +A recipient name of "MULTIPLE RECIPIENTS" indicates that the financial assistance award has been aggregated to protect the Personally Identifiable Information (PII) of a collection of individuals. Agencies are prohibited from publishing PII on USAspending. Aggregating involves grouping awards to individuals (typically from the same program and time period) by county (for domestic awards), state (for domestic awards), or country (for foreign awards). These records omit location information that would normally be present (street address and the last 4 digits of the ZIP code) and replace the recipient name with “MULTIPLE RECIPIENTS.” The award summary pages for these records specify the level of aggregation. + +## NAICS + +NAICS stands for the North American Industrial Classification System. This 6-digit code tells you what industry the work falls into. Each contract record has a NAICS code. That means you can look up how much money the U.S. government spent in a specific industry. + +The list of industries and codes is updated every 5 years. + +**Official definition:** The identifier and title that represents the North American Industrial Classification System Code assigned to the solicitation and resulting award identifying the industry in which the contract requirements are normally performed + +## National Interest Action (NIA) + +The National Interest Action (NIA) code categorizes federal contracts that are related to emergency responses or other nationally significant events. + +**Official definition:** The National Interest Action values are used to categorize procurement actions related to emergency contingency responses or other nationally significant events. The length of the value is no more than 4 characters. A new NIA value was created to address the COVID-19 pandemic and this value is valid for actions signed between 3/13/2020 and 9/30/2020. + +Below are examples of NIA values: + - H19M – Hurricane Michael 2019 + - H19D – Hurricane Dorian 2019 + - P20C – COVID-19 2020 + +Note that the Disaster Emergency Fund Code (DEFC) is also used to track COVID-19 spending. However, it is not limited to contracts and is necessarily tied to COVID-19 supplemental appropriations. Thus, awards with the COVID-19 NIA value may not have a COVID-19 DEFC value, and vice versa. + +## Non-Federal Funding Amount + +The amount of the award funded by non-Federal source(s), in dollars. Program Income (as defined in 2 CFR § 200.1) is not included until such time that Program Income is generated and credited to the agreement. + +Award obligation and award outlay amounts (from Files C, D1, and D2) only count dollars spent from federal funding, not any dollars spent from non-federal funding. + +## Object Class + +Object class is one way to classify financial data in the federal budget. An object class groups obligations by the types of items or services purchased by the federal government. Examples: "Personnel Compensation" and "Equipment" + +**Official definition:** Categories in a classification system that presents obligations by the items or services purchased by the Federal Government. Each specific object class is defined in OMB Circular A-11 § 83.6. + +(defined in OMB Circular A-11) + +## Obligation + +When awarding funding, the U.S. government enters a binding agreement called an obligation. The government promises to spend the money, either immediately or in the future. An agency incurs an obligation, for example, when it places an order, signs a contract, awards a grant, purchases a service, or takes other actions that require it to make a payment. + +Loan Subsidy Cost has a direct budgetary impact and is factored into obligations and outlays when it is positive. + +**Official definition:** Obligation means a legally binding agreement that will result in outlays, immediately or in the future. When you place an order, sign a contract, award a grant, purchase a service, or take other actions that require the Government to make payments to the public or from one Government account to another, you incur an obligation. It is a violation of the Antideficiency Act (31 U.S.C. § 1341(a)) to involve the Federal Government in a contract or obligation for payment of money before an appropriation is made, unless authorized by law. This means you cannot incur obligations in a vacuum; you incur an obligation against budget authority in a Treasury account that belongs to your agency. It is a violation of the Antideficiency Act to incur an obligation in an amount greater than the amount available in the Treasury account that is available. This means that the account must have budget authority sufficient to cover the total of such obligations at the time the obligation is incurred. In addition, the obligation you incur must conform to other applicable provisions of law, and you must be able to support the amounts reported by the documentary evidence required by 31 U.S.C. § 1501. Moreover, you are required to maintain certifications and records showing that the amounts have been obligated (31 U.S.C. § 1108). The following subsections provide additional guidance on when to record obligations for the different types of goods and services or the amount. + + + +Additional detail is provided in Circular A‐11. + +## Ordering Period End Date + +For procurement, the date on which, for the award referred to by the action being reported, no additional orders referring to it may be placed. This date applies only to procurement indefinite delivery vehicles (such as indefinite delivery contracts or blanket purchase agreements). Administrative actions related to this award may continue to occur after this date. The period of performance end dates for procurement orders issued under the indefinite delivery vehicle may extend beyond this date. + +## Other Budgetary Resources + +A subset of budget authority. Most spending by agencies is authorized by appropriation laws; a small amount may come from money not spent in the previous year. The rest is authorized in other ways and grouped together on USAspending.gov as Other Budgetary Resources. + +**Official definition:** New borrowing authority, contract authority, and spending authority from offsetting collections provided by Congress in an appropriations act or other legislation, or unobligated balances of budgetary resources made available in previous legislation, to incur obligations and to make outlays. + +(defined in OMB Circular A-11) + +## Other Financial Assistance + +Financial assistance from the Federal Government that is not described by any of the previously-defined assistance types. + +## Other Object Class + +This major object class includes other miscellaneous charges. + +**Official definition:** This major object class covers object classes 91.0 through 99.5. This includes: +91.0 Unvouchered +92.0 Undistributed +94.0 Financial transfers +99.0 Subtotal, obligations +99.5 Adjustment for rounding + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Other Transaction (OT) Indefinite Delivery Vehicle (IDV) + +An Other Transaction (OT) Indefinite Delivery Vehicle is a transaction other than a procurement contract, grant, or cooperative agreement. Since this transaction is defined in the negative, it could take unlimited potential forms. This term is often used to refer to transactions designed to: + +- Support research & development for homeland security. +- Advance the development, testing, and deployment of critical homeland security technologies. +- Speed up prototyping and deployment of technologies addressing homeland security vulnerabilities. + +The Department of Homeland Security (DHS) often splits its use of OT's for Research and Prototype Projects. + +## Outlay + +An outlay occurs when federal money is actually paid out, not just promised to be paid ("obligated"). + +**Official definition:** Payments made to liquidate an obligation (other than the repayment of debt principal or other disbursements that are “means of financing” transactions). Outlays generally are equal to cash disbursements but also are recorded for cash-equivalent transactions, such as the issuance of debentures to pay insurance claims, and in a few cases are recorded on an accrual basis such as interest on public issues of the public debt. Outlays are the measure of Government spending. + +(defined in OMB Circular A-11) + +## Parent Award Identification (ID) Number + +The identifier of the procurement award under which the specific award is issued, such as a Federal Supply Schedule. This data element currently applies to procurement actions only. + +## Parent DUNS + +The unique identification number for the ultimate parent of an awardee or recipient. Currently the identifier is the 9-digit number maintained by Dun & Bradstreet as the global parent DUNS® number. + +## Period of Performance Current End Date + +The date that the award ends, as agreed upon by the parties involved without exercising any pre-determined extension options. Note that the latest transaction for the award (known as the Latest Transaction Action Date) may be different than this date. + +**Official definition:** For procurement awards: The contract completion date based on the schedule in the contract. For an initial award, this is the scheduled completion date for the base contract and for any options exercised at time of award. For modifications that exercise options or that shorten (such as termination) or extend the contract period of performance, this is the revised scheduled completion date for the base contract including exercised options. If the award is solely for the purchase of supplies to be delivered, the completion date should correspond to the latest delivery date on the base contract and any exercised options. The completion date does not change to reflect a closeout date. + +For grants and cooperative agreements: The Period of Performance is defined in the CFR 200 as the total estimated time interval between the start of an initial Federal award and the planned end date, which may include one or more funded portions, or budget periods. If the end date is revised due to an extension, termination, lack of available funds, or other reason, the current end date will be amended. + +For all other financial assistance awards: The current date on which, for the award referred to by the action being reported, awardee effort completes or the award is otherwise ended. Administrative actions related to this award may continue to occur after this date. + +Note that the latest transaction for the award (known as the Latest Transaction Action Date) may be different than Period of Performance Current End Date. + +## Period of Performance Potential End Date + +The date that the award ends, as agreed upon by the parties involved after exercising any pre-determined extension options. Note that the latest transaction for the award (known as the Latest Transaction Action Date) may be different than this date. + +Administrative actions related to this award may continue to occur after the Period of Performance Potential End Date. + +The Period of Performance Potential End Date does not apply to Contract Indefinite Delivery Vehicles under which Definitive Contracts may be awarded. + +## Period of Performance Start Date + +The date that the award begins, as agreed upon by the parties involved. Note that the first transaction for the award (known as the Base Transaction Action Date) may be different than this date. + +**Official definition:** For procurement awards: Per the FPDS data dictionary, the date that the parties agree will be the starting date for the contract's requirements. This is the period of performance start date for the entire contract period, this date does not reflect period of performance per modification, but rather the start of the entire contract period of performance. This data element does NOT correspond to FAR 43.101 or 52.243 and should not be mapped to those fields in your contract writing systems. + +For grants and cooperative agreements: The Period of Performance is defined in the 2 CFR 200 as the total estimated time interval between the start of an initial Federal award and the planned end date, which may include one or more funded portions, or budget periods. + +For all other financial assistance awards: The date on which, for the award referred to by the action being reported, awardee effort begins or the award is otherwise effective. + +Note that the first transaction for the award (known as the Base Transaction Action Date) may be different than the Period of Performance Start Date. + +## Personnel Compensation and Benefits + +This major object class includes employee compensation, including salaries, wages, and health benefits, for federal employees. Personnel compensation and benefits apply to full-time and part-time employees, along with military personnel. + +**Official definition:** This major object class consists of object classes 11, 12, and 13. This includes: +11 Personnel compensation +11.1 Full-time permanent +11.3 Other than full-time +permanent +11.5 Other personnel +compensation +11.6 Military personnel - +basic allowance for +housing +11.7 Military personnel +11.8 Special personal services +payments +11.9 Total personnel +compensation +12 Personnel benefits +12.1 Civilian personnel +benefits +12.2 Military personnel +benefits +13.0 Benefits for former +personnel + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Potential Award Amount + +The total amount that could be obligated on a contract. This total includes the base plus options amount. For example, if a recipient is awarded $10M on a base contract with 3 option years at $1M each, the potential award amount is $13M. + +**Official definition:** For procurement, the total amount that could be obligated on a contract, if the base and all options are exercised. + +## Primary Place of Performance + +The principal place of business, where the majority of the work is performed. For example, in a manufacturing contract, this would be the main plant where items are produced. + +**Official definition:** The address where the predominant performance of the award will be accomplished. The address is made up of four components: City, State Code, and ZIP+4 or Postal Code. + +## Primary Place of Performance Congressional District + +The congressional district where the principal place of business, where the majority of the work is performed. For example, in a manufacturing contract, this would be the main plant where items are produced. + +**Official definition:** U.S. congressional district where the predominant performance of the award will be accomplished. This data element will be derived from the Primary Place of Performance Address. + +## Primary Place of Performance Country + +The country where the principal place of business, where the majority of the work is performed. For example, in a manufacturing contract, this would be the main plant where items are produced. + +**Official definition:** Country code where the predominant performance of the award will be accomplished. + +## Prime Award + +A prime award is an agreement that the government makes with a non-federal entity for the purpose of carrying out a federal program. The entities receiving the prime award are known as prime recipients. + +The term “prime award” can be used as a generic term to describe either transactions or prime award summaries. + +**Official definition:** A Prime Award is a a federal award that is either: +(1) Federal financial assistance that a non-Federal entity receives directly from a Federal awarding agency; or +(2) The cost-reimbursement contract under the Federal Acquisition Regulations that a non-Federal entity receives directly from a Federal awarding agency. +(Adapted from 2 CFR §200.38) + +## Prime Award Summary + +A prime award summary includes all related prime award transactions that share the same prime award unique key. Award Profile pages on USAspending.gov allow users to browse individual prime award summaries, including the list of transactions that constitute the prime award summary, the list of sub-awards funded by the prime award summary, and the list of federal accounts which have funded the prime award summary. + +Generally speaking, information from the most recent prime award transaction is applied to the summary-level information in the prime award summary. For example, the award’s recipient name, awarding agency, and period of performance at the summary level is drawn from the latest transaction of that award. + +## Prime Recipient + +A company, organization, individual, or government entity (i.e., state, local, tribal, or foreign) that receives funding directly from the U.S. government. They receive this funding through an agreement called a prime award. For example, if the Dept. of Transporation is building a bridge, they can award Bridge Company A the contract to carry out the construction. Bridge Company A would be the prime recipient. + +**Official definition:** A non-Federal entity that receives a Federal award directly from a Federal awarding agency to carry out an activity under a Federal program. + +## Procurement Instrument Identifier (PIID) + +A unique identifier assigned to a federal contract, purchase order, basic ordering agreement, basic agreement, and blanket purchase agreement. It is used to track the contract and any modifications or transactions related to it. + +**Official definition:** The unique identifier of the specific award being reported. + +[Read more in the Federal Acquisition Regulation](https://www.acquisition.gov/far/html/Subpart%204_16.html). + +## Product or Service Code (PSC) + +A Product or Service Code (PSC) is a 4-character code that identifies the type of product, service, or research & development (R&D) purchased. While NAICS codes identify the industry most relevant to a contract, PSCs tell you what the contract is specifically purchasing. For example, a contract’s NAICS code might point to the “Industrial Building Construction” industry, while that same contract’s PSC points to “Construct Hospitals and Infirmaries.” There are nearly three times as many PSCs (over 2,900) as there are NAICS codes (just over 1000), which in many cases allows a more granular PSC designation than NAICS code designation for a given contract. + +All PSC are 4 characters long, but there is an embedded hierarchy in the codes. + +- **R&D**: begin with ‘A’ (indicating R&D), followed by a second letter, followed by a number, followed by a number (four levels of hierarchy). Example: AA11. + +- **Services**: begin with ‘B’ to ‘Z’ (indicating the subcategory of Service), followed by a number, followed by two letters (four levels of hierarchy if you include the “Service” designation). Example: C1AA + +- **Products**: begin with two numbers (indicating the subcategory of Product), followed by two more numbers (three levels of hierarchy if you include the “Product” designation). Example: 1005 + +**Official definition:** The code that best identifies the product or service procured. Codes are defined in the Product and Service Codes Manual. + +## Program Activity + +A program activity is a category within an appropriation account. A program activity is a specific activity or project, as listed in the program and financing schedules of the annual budget of the U.S. government. + +**Official definition:** A specific activity or project as listed in the program and financing schedules of the annual budget of the United States Government. + +According to OMB Circular A-11, The activities should: +- Clearly indicate the services to be performed or the programs to be conducted; +- Finance no more than one strategic goal or objective; +- Distinguish investment, developmental, grant and subsidy, and operating programs; and +- Relate to administrative control and operation of the agency. + +## Program, System, and Equipment Code + +A system-generated Department of Defense (DOD) code, also known as the Acquisition Program (AP) Code. This code identifies the DOD program, weapons system, or equipment being acquired. It can be categorized as a Major Defense Acquisition Program (MDAP) or a Major Automated Information System (MAIS). + +**Official definition:** Two codes that together identify the program and weapons system or equipment purchased by a DOD agency. The first character is a number 1-4 that identifies the DOD component. The last 3 characters identify that component's program, system, or equipment. + +[Read more about this code](https://www.fpds.gov/help/SystemEquipment.htm) on the General Services Administration website. + +## Project Grant + +Funding of specific projects for a fixed amount of time. Some examples include fellowships, scholarships, research grants, survey grants, and construction grants. + +**Official definition:** Project grants provide federal funding for fixed or known periods for specific projects or the delivery of specific services or products. + +## Purchase Order + +A Purchase Order is an offer by the government established to buy supplies or services, including construction and research and development, upon specified terms and conditions, using simplified acquisition procedures. + +## Reason for Modification + +Provides information on the type of change made to an award. + +**Official definition:** Description (and corresponding code) that provides information on any changes made to the Federal prime award. There are typically multiple actions for each award. + +(Note: This definition encompasses current data elements ‘Type of Action’ for financial assistance and ‘Reason for Modification’ for procurement) + +## Recipient + +A company, organization, individual, or government entity (i.e., state, local, tribal, federal, or foreign), that receives funding from the U.S. government. + +## Recipient Congressional District + +The congressional district in which the recipient is located. + +**Official definition:** The congressional district in which the awardee or recipient is located. This is not a required data element for non-U.S. addresses. + +## Recipient Location + +Legal business address of the recipient. + +**Official definition:** The awardee or recipient’s legal business address where the office represented by the Unique Entity Identifier (as registered in the System for Award Management) is located. In most cases, this should match what the entity has filed with the State in its organizational documents, if required. The address is made up of five components: Address Lines 1 and 2, City, State Code, and ZIP+4 or Postal Code. + +## Recipient Name + +A recipient is a company, organization, individual, or government entity (i.e., state, local, tribal, federal, or foreign), that received funding by the U.S. government. The recipient name is the same as what's registered in the System for Award Management (SAM.gov). This is usually the official name of the business. For individuals, the term 'Multiple Recipients' is used as the Recipient Name to protect individuals' privacy. + +**Official definition:** The name of the awardee or recipient that relates to the unique identifier. For U.S. based companies, this name is what the business ordinarily files in formation documents with individual states (when required). + +## Recipient/Business Types + +Recipient/Business types are socio-economic and other organizational/business characteristics that are used to categorize federal contractors and other funding recipients. There are many different recipient/business types, and they span for-profit businesses, non-profits, government entities, individuals, and foreign entities. Some examples are: + +- Historically Black College or University +- Veteran-Owned Business +- Historically Underutilized Business Zone (HUBZone) Firm +- Sole Proprietorship +- Foundation + +You can search and filter on all recipient types on this site. + +**Official definition:** A collection of indicators of different types of recipients based on socio-economic status and organization / business areas. + +## Record Type + +Code indicating whether an action is an Aggregate Record (Record Type = 1), a Non-aggregate Record (Record Type = 2), or a Non-Aggregate Record to an Individual Recipient with Redacted Personally Identifiable Information (Record Type = 3). + +## Redacted Due To PII + +A recipient name of "REDACTED DUE TO PII" indicates that the associated financial assistance award was issued to an individual whose name and other Personally Identifiable Information (PII) were redacted, as required by law. Along with masking the individual’s name with “REDACTED DUE TO PII,” these records omit location information that would otherwise be present (street address and the last 4 digits of the ZIP code). + +## Set Aside Type + +A tool used to award contracts to specific types of businesses. Most set asides reserve contracts for small businesses. Others are more specific, to support small businesses with specific designations, such as veteran owned business or small disadvantaged business types. + +**Official definition:** The designator for type of set aside determined for the contract action. + +## Simplified Acquisition Procedures (SAP) + +For certain types of government purchases between $3,000 and $150,000. These purchases may require less approval and less documentation. + +## Solicitation + +When an agency needs work done, it can ask for information or bids on the work. These requests are called solicitations. They often come as a RFI (Request for Information) or RFP (Request for Proposal). + +## Spending + +On this site, the term spending could either describe obligations (amount awarded) or outlays (amount paid out). + +## Sub Account Code + +Sub Account Code (SUB) is a component of the TAS that identifies a Treasury-defined subdivision of a Federal Account (AID + MAIN). Most Federal Accounts do not have subdivisions. 000 is the default SUB; if 000 is the only SUB under a given Federal Account, it has not been subdivided + +**Official definition:** This is a component of the TAS. Identifies a Treasury-defined subdivision of the main account. This field cannot be blank. Sub Account 000 indicates the Parent account. + +## Sub-Award + +A sub-award is an agreement that a prime recipient makes with another entity to perform a portion of their award. On our website, these recipients are known as sub-recipients. Sub-awards might also be referred to as a sub-contract or a sub-grant. Sub-award amounts are funded by prime award obligations and outlays. In theory, the total value of all sub-award amounts for any given prime award is a subset of the Current Award Amount for that prime award; sub-award amounts generally should not exceed the Current Award Amount for their associated prime award. To avoid double-counting the overall value of a prime award, do not sum up sub-award amounts and prime award obligations or outlays. + +**Official definition:** An award provided by a pass-through entity to a subrecipient for the subrecipient to carry out part of a federal award received by the pass-through entity. It does not include payments to a contractor or payments to an individual that is a beneficiary of a federal program. A subaward may be provided through any form of legal agreement, including an agreement that the pass-through entity considers a contract. (2CFR) + +## Sub-Recipient + +A company, organization, individual, or government entity (i.e., state, local, tribal, or foreign) that receives funding from another recipient of federal funds (a prime recipient), rather than directly from the U.S. government. The sub-recipient may be a sub-contractor or a sub-grantee. For example, the Dept. of Transporation awards Bridge Company A a bridge construction contract. Bridge Company A needs Bridge Company B to supply the steel, so Bridge Company A awards Bridge Company B a sub-award. Bridge Company B is the sub-contractor. On the grants side, University A receives an R&D grant from the National Science Foundation. University A needs University B to perform the initial step in the research, so University A awards University B a sub-award. University B is the sub-grantee. + +**Official definition:** A non-Federal entity that receives a sub-award from a pass-through entity to carry out part of a federal program; but does not include an individual that is the beneficiary of such program. (grants.gov) + +## Submission Period + +The submission period shows when federal agencies submit their financial data. It is displayed as a fiscal year (e.g., “FY 2020” or “FY20” for fiscal year 2020, covering October 2019 through September 2020) followed by a month (e.g., “P01” for October, which is the first month of the fiscal year) or quarter (e.g., “Q1” for the first quarter of the fiscal year, covering October through December). For example, “FY19 P10” indicates a submission whose data covers the period of July 2019. + +Starting with the June 2020 reporting period, most federal agencies began submitting their account data (Files A, B, and C) to the Treasury DATA Act Broker on a monthly basis rather than on the previous quarterly schedule. As of October 2021 (FY22 Q1), all agencies are required to report on a monthly basis. More information about the agency account data reporting policy is found in OMB’s Memorandum M-20-21 (Appendix A, Section III). + +## Task Order Contract + +An Indefinite Quantity Contract for services (not supplies) is sometimes referred to as a Task Order Contract. With this type of contract, the government promises to buy services over a period of time from a vendor. Instead of an exact amount, it sets a range with a minimum and maximum. + +## Transaction + +A transaction can be the initial contract, grant, loan, or insurance award or any amendment or modification to that award. + +## Transaction Description + +A brief description of the purpose of the transaction. + +## Treasury Account Symbol (TAS) + +Treasury and OMB assign a code to each appropriation, receipt, or fund account. This code is similar to a bank account number. It helps identify financial transactions in the federal government. It also aids in reporting accuracy. TAS are sometimes referred as ‘program source’ in legislation. On this website, we group each set of Treasury Accounts that share an Agency Identifier and Main Account Code into a "Federal Account". + +Seven components make up the TAS: + +- Allocation Transfer Agency Identifier (ex. 089) +- Agency Identifier (ex. 020) +- Beginning Period of Availability (ex. 2017) +- Ending Period of Availability (ex. 2018) +- Availability Type Code (used if there are not specific beginning/ending years) (ex. X) +- Main Account Code (ex. 0114) +- Sub Account Code (ex. 000) + +Example TAS: + +- 089-020-2017/2018-0114-000 +- 089-020-2017/2017-0114-000 +- 089-020-X-0114-000 + +**Official definition:** Treasury Account Symbol: The account identification codes assigned by the Department of the Treasury to individual appropriation, receipt, or other fund accounts. All financial transactions of the Federal Government are classified by TAS for reporting to the Department of the Treasury and the Office of Management and Budget. + +(defined in OMB Circular A-11) + +## Ultimate Parent Legal Entity Name + +The name of the ultimate parent of the awardee or recipient. + +## Unique Entity Identifier (UEI) + +The Unique Entity Identifier (UEI) for an awardee or recipient is an alphanumeric code created in the System for Award Management (SAM.gov) that is used to uniquely identify specific commercial, nonprofit, or business entities registered to do business with the federal government. + +## Unlinked Award + +There are two distinct datasets transmitted to USAspending for agency awards—File C and Files D. File C is submitted and published on the site on a monthly or quarterly basis from audited agency financial systems. File D1 (procurement) and File D2 (financial assistance) data is generated from award reporting data submitted by agencies to other systems and updated on USAspending as frequently as daily. Because these data originate from different communities and systems within agencies that are subject to different policies and reporting requirements, there are sometimes gaps between the awards captured in each dataset. + +Unlinked awards lack a shared award ID that allows a match between financial system data and award reporting data. As a result, such awards only show up in some parts of the site and are missing their full context. For example, awards found in File C but not in File D lack recipient and CFDA Program information and thus, will not have an Award Summary page. + +## Unobligated Balance + +The amount of money out of an account that has yet to be awarded or obligated (promised to be spent). + +**Official definition:** Unobligated balance means the cumulative amount of budget authority that remains available for obligation under law in unexpired accounts at a point in time. The term “expired balances available for adjustment only” refers to unobligated amounts in expired accounts. + + + +Additional detail is provided in Circular A‐11. + +## Unreported Data + +There are various reasons financial or award data is not reported by agencies or otherwise available to USAspending.gov at a given time. These include, but are not limited to, timing of data availability, or sensitive data that is not subject to submission. Where possible, USAspending.gov advises readers that other information exists that cannot be detailed. + +## URI + +URI stands for Unique Record Identifier. A URI is an agency-defined identifier that is unique for every financial assistance action reported by that agency.

The `total_obligation` column is a snapshot at each transaction and may not reflect the final total. +- **Contract ceiling vs obligation**: `base_and_all_options_value` is the potential maximum; `total_obligation` is what's actually committed. A contract may have $10M obligated against a $500M ceiling. +- **Parent company roll-up**: Use `COALESCE(NULLIF(recipient_parent_name, ''), recipient_name)` to group subsidiaries under their parent. Only populated for contracts. +- **recipient_name** may vary slightly for the same entity across rows (e.g., 'BOEING CO' vs 'THE BOEING COMPANY'). Use `LIKE` or `UPPER()` for fuzzy matching. +- **award_type** is derived from USAspending type codes: A/B/C/D -> 'contract', 02-05 -> 'grant', IDV_* -> 'idv'. +- **federal_action_obligation** can be negative (de-obligations, corrections). Sum them to get net spending. +- **naics_code** and **naics_description** are only populated for contracts; empty for grants/assistance. +- **psc_code** contains Product/Service Codes for contracts and CFDA numbers for assistance awards. **psc_description** contains the corresponding description. These are different classification systems stored in the same column. +- **Contracts-only columns**: `base_and_all_options_value`, `recipient_parent_name`, `parent_award_piid`, `extent_competed`, `type_of_set_aside`, `number_of_offers`, `contract_pricing_type` are only populated for contracts/IDVs. +- **Grants-only columns**: `business_types` is only populated for assistance awards. diff --git a/examples/sandbox/extensions/daytona/usaspending_text2sql/setup_db.py b/examples/sandbox/extensions/daytona/usaspending_text2sql/setup_db.py new file mode 100644 index 00000000..cec79428 --- /dev/null +++ b/examples/sandbox/extensions/daytona/usaspending_text2sql/setup_db.py @@ -0,0 +1,702 @@ +#!/usr/bin/env python3 +"""Download NASA spending data from USAspending.gov and build a SQLite database. + +This script is designed to run inside a sandbox environment with only Python +stdlib available.

The workflow picks which backend to target each turn by calling +`temporal_sandbox_client(name)` in its `RunConfig`. + +**Files:** + +- `temporal_sandbox_agent.py` -- The `AgentWorkflow` definition and worker + entrypoint. Each conversation turn calls `Runner.run()` with a + `SandboxRunConfig` that targets the active backend. The workflow is + long-lived: it idles between turns and persists indefinitely in Temporal. +- `temporal_session_manager.py` -- A singleton `SessionManagerWorkflow` that + tracks active sessions and handles create, fork, switch, and destroy + operations. +- `temporal_sandbox_tui.py` -- A [Textual](https://textual.textualize.io/) TUI + that connects to the session manager and drives conversations via signals, + updates, and queries. +- `examples/sandbox/misc/workspace_shell.py` -- A shared `Capability` that + gives the agent a shell tool for running commands in the sandbox workspace. + +**Switching backends** is an in-place operation: the workflow receives a +`switch_backend` update, changes its backend and manifest, clears the +backend-specific session state, and the next turn creates a fresh session on +the new backend. The portable snapshot is preserved so workspace files carry +over. + +**Forking** pauses the source workflow, snapshots its state and conversation +history, and starts a new child workflow on the chosen backend.

straightforward benefits question. +- `referral_status_check` adds a referral lookup. +- `blue_cross_pt_benefits` shows a follow-up turn that benefits from the shared SQLite memory. +- `prior_auth_confusion_ct` focuses on prior-authorization and intake-routing confusion. +- `billing_coverage_clarification` combines benefits lookup with sandbox policy search and document + generation. +- `messy_ambiguous_knee_case` triggers the human approval flow before queueing a handoff. + +## Run the CLI demo + +From the repository root: + +```bash +uv run python examples/sandbox/healthcare_support/main.py +``` + +Useful options: + +```bash +uv run python examples/sandbox/healthcare_support/main.py --list-scenarios +uv run python

[`workflow.py`](./workflow.py) contains the shared workflow execution logic, sandbox setup, + artifact copying, tracing, and approval resume loop. +- [`support_agents.py`](./support_agents.py) defines the orchestrator, benefits subagent, sandbox + policy agent, and memory recap agent. +- [`tools.py`](./tools.py) defines the local lookup tools and the approval-gated human handoff tool. +-

When working in a subdirectory of CWD, or a directory outside the CWD, check for any AGENTS.md files that may be applicable. + +## Responsiveness + +### Preamble messages + +Before making tool calls, send a brief preamble to the user explaining what you’re about to do. When sending preamble messages, follow these principles and examples: + +- **Logically group related actions**: if you’re about to run several related commands, describe them together in one preamble rather than sending a separate note for each. +- **Keep it concise**: be no more than 1-2 sentences, focused on immediate, tangible next steps. (8–12 words for quick updates). +- **Build on prior context**: if this is not your first tool call, use the preamble message to connect the dots with what’s been done so far and create a sense of momentum and clarity for the user to understand your next actions. +- **Keep your tone light, friendly and curious**: add small touches of personality in preambles feel collaborative and engaging. +- **Exception**: Avoid adding a preamble for every trivial read (e.g., `cat` a single file) unless it’s part of a larger grouped action. + +**Examples:** + +- “I’ve explored the workspace; now checking the relevant files.” +- “Next, I’ll update the config and verify the related behavior.” +- “I’m about to set up the commands and helper steps.” +- “Ok cool, so I’ve wrapped my head around the workspace.

Please keep going until the query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved. Autonomously resolve the query to the best of your ability, using the tools available to you, before coming back to the user. Do NOT guess or make up an answer. + +You MUST adhere to the following criteria when solving queries: + +- Working on the repo(s) in the current environment is allowed, even if they are proprietary. +- Analyzing code for vulnerabilities is allowed. +- Showing user code and tool call details is allowed. +- Use the `apply_patch` tool to edit files (NEVER try `applypatch` or `apply-patch`, only `apply_patch`): {"command":["apply_patch","*** Begin Patch\\n*** Update File: path/to/file.py\\n@@ def example():\\n- pass\\n+ return 123\\n*** End Patch"]} + +If completing the user's task requires writing or modifying files, your code and final answer should follow these coding guidelines, though user instructions (i.e. AGENTS.md) may override these guidelines: + +- Fix the problem at the root cause rather than applying surface-level patches, when possible. +- Avoid unneeded complexity in your solution. +- Do not attempt to fix unrelated bugs or broken tests. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) +- Update documentation as necessary. +- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task. +- Use `git log` and `git blame` to search the history of the codebase if additional context is required. +- NEVER add copyright or license headers unless specifically requested. +- Do not waste tokens by re-reading files after calling `apply_patch` on them. The tool call will fail if it didn't work. The same goes for making folders, deleting folders, etc. +- Do not `git commit` your changes or create new git branches unless explicitly requested. +- Do not add inline comments within code unless explicitly requested. +- Do not use one-letter variable names unless explicitly requested. +- NEVER output inline citations like "【F:README.md†L5-L14】" in your outputs. The CLI is not able to render these so they will just be broken in the UI. Instead, if you output valid filepaths, users will be able to click on them to open the files in their editor. + +## Validating your work + +If the codebase has tests or the ability to build or run, consider using them to verify that your work is complete. + +When testing, your philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests. + +Similarly, once you're confident in correctness, you can suggest or use formatting commands to ensure that your code is well formatted. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one. + +For all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) + +Be mindful of whether to run validation commands proactively. In the absence of behavioral guidance: + +- When running in non-interactive approval modes like **never** or **on-failure**, proactively run tests, lint and do whatever you need to ensure you've completed the task. +- When working in interactive approval modes like **untrusted**, or **on-request**, hold off on running tests or lint commands until the user is ready for you to finalize your output, because these commands take time to run and slow down iteration. Instead suggest what you want to do next, and let the user confirm first. +- When working on test-related tasks, such as adding tests, fixing tests, or reproducing a bug to verify behavior, you may proactively run tests regardless of approval mode. Use your judgement to decide whether this is a test-related task. + +## Ambition vs. precision + +For tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation. + +If you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature. + +You should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified. + +## Sharing progress updates + +For especially longer tasks that you work on (i.e. requiring many tool calls, or a plan with multiple steps), you should provide progress updates back to the user at reasonable intervals. These updates should be structured as a concise sentence or two (no more than 8-10 words long) recapping progress so far in plain language: this update demonstrates your understanding of what needs to be done, progress so far (i.e. files explores, subtasks complete), and where you're going next. + +Before doing large chunks of work that may incur latency as experienced by the user (i.e. writing a new file), you should send a concise message to the user with an update indicating what you're about to do to ensure they know what you're spending time on. Don't start editing or writing large files before informing the user what you are doing and why. + +The messages you send before tool calls should describe what is immediately about to be done next in very concise language. If there was previous work done, this preamble message should also include a note about the work done so far to bring the user along. + +## Presenting your work and final message + +Your final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user’s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges. + +You can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option. Reserve multi-section structured responses for results that need grouping or explanation. + +The user is working on the same computer as you, and has access to your work. As such there's no need to show the full contents of large files you have already written unless the user explicitly asks for them. Similarly, if you've created or modified files using `apply_patch`, there's no need to tell users to "save the file" or "copy the code into a file"—just reference the file path. + +If there's something that you think you could help with as a logical next step, concisely ask the user if they want you to do so. Good examples of this are running tests, committing changes, or building out the next logical component. If there’s something that you couldn't do (even with approval) but that the user might want to do (such as verifying changes by running the app), include those instructions succinctly. + +Brevity is very important as a default. You should be very concise (i.e. no more than 10 lines), but can relax this requirement for tasks where additional detail and comprehensiveness is important for the user's understanding. + +### Final answer structure and style guidelines + +You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value. + +**Section Headers** + +- Use only when they improve clarity — they are not mandatory for every answer. +- Choose descriptive names that fit the content +- Keep headers short (1–3 words) and in `**Title Case**`. Always start headers with `**` and end with `**` +- Leave no blank line before the first bullet under a header. +- Section headers should only be used where they genuinely improve scanability; avoid fragmenting the answer. + +**Bullets** + +- Use `-` followed by a space for every bullet. +- Merge related points when possible; avoid a bullet for every trivial detail. +- Keep bullets to one line unless breaking for clarity is unavoidable. +- Group into short lists (4–6 bullets) ordered by importance. +- Use consistent keyword phrasing and formatting across sections. + +**Monospace** + +- Wrap all commands, file paths, env vars, and code identifiers in backticks (`` `...` ``). +- Apply to inline examples and to bullet keywords if the keyword itself is a literal file/command. +- Never mix monospace and bold markers; choose one based on whether it’s a keyword (`**`) or inline code/path (`` ` ``). + +**File References** +When referencing files in your response, make sure to include the relevant start line and always follow the below rules: + * Use inline code to make file paths clickable. + * Each reference should have a stand alone path. Even if it's the same file. + * Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix. + * Line/column (1‑based, optional): :line[:column] or #Lline[Ccolumn] (column defaults to 1). + * Do not use URIs like file://, vscode://, or https://. + * Do not provide range of lines + * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\workspace\project\main.rs:12:5 + +**Structure** + +- Place related bullets together; don’t mix unrelated concepts in the same section. +- Order sections from general → specific → supporting info. +- For subsections (e.g., “Binaries” under “Rust Workspace”), introduce with a bolded keyword bullet, then list items under it. +- Match structure to complexity: + - Multi-part or detailed results → use clear headers and grouped bullets. + - Simple results → minimal headers, possibly just a short list or paragraph. + +**Tone** + +- Keep the voice collaborative and natural, like a helpful teammate handing off work. +- Be concise and factual — no filler or conversational commentary and avoid unnecessary repetition +- Use present tense and active voice (e.g., “Runs tests” not “This will run tests”). +- Keep descriptions self-contained; don’t refer to “above” or “below”. +- Use parallel structure in lists for consistency. + +**Don’t** + +- Don’t use literal words “bold” or “monospace” in the content. +- Don’t nest bullets or create deep hierarchies. +- Don’t output ANSI escape codes directly — the CLI renderer applies them. +- Don’t cram unrelated keywords into a single bullet; split for clarity. +- Don’t let keyword lists run long — wrap or reformat for scanability. + +Generally, ensure your final answers adapt their shape and depth to the request. For example, answers to file or task explanations should have a precise, structured explanation with concrete references that answer the question directly. For tasks with a simple implementation, lead with the outcome and supplement only with what’s needed for clarity. Larger changes can be presented as a logical walkthrough of your approach, grouping related steps, explaining rationale where it adds value, and highlighting next actions to accelerate the user. Your answers should provide the right level of detail while being easily scannable. + +For casual greetings, acknowledgements, or other one-off conversational messages that are not delivering substantive information or structured results, respond naturally without section headers or bullet formatting. + +# Tool Guidelines + +## Shell commands + +When using the shell, you must adhere to the following guidelines: + +- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.) +- Do not use python scripts to attempt to output larger chunks of a file. diff --git a/src/agents/sandbox/manifest.py

Do not introduce extra flourish or abstraction if that would +make the profile less faithful to the underlying memory. +Be conservative about profile inferences: avoid turning one-off conversational impressions, +flattering judgments, or isolated interactions into durable user-profile claims. + +For example, include (when known): + +- What they do / care about most (roles, recurring projects, goals) +- Typical workflows and tools (how they like to work, how they use agents, preferred formats) +- Communication preferences (tone, structure, what annoys them, what “good” looks like) +- Reusable constraints and gotchas (env quirks, constraints, defaults, “always/never” rules) +- Repeatedly observed follow-up patterns that future agents can proactively satisfy +- Stable user operating preferences preserved in `MEMORY.md` `## User preferences` sections + +You may end with short fun facts if they are real and useful, but keep the main profile concrete +and grounded.

Prefer +brief descriptions over long ones. + +For example, include (when known): + +- Collaboration preferences: tone/structure the user likes, what “good” looks like, what to avoid. +- Workflow and environment: runtime conventions, common commands/scripts, recurring setup steps. +- Decision heuristics: rules of thumb that improved outcomes (e.g. when to consult + memory, when to stop searching and try a different approach). +- Tooling habits: effective tool-call order, good search keywords, how to minimize + churn, how to verify assumptions quickly. +- Verification habits: the user’s expectations for tests/lints/sanity checks, and what + “done” means in practice. +- Pitfalls and fixes: recurring failure modes, common symptoms/error strings to watch for, and the proven fix. +- Reusable artifacts: templates/checklists/snippets that consistently used and helped + in the past (what they’re for and when to use them). +- Efficiency tips: ways to reduce tool calls/tokens, stop rules, and when to switch strategies. +- Give extra weight to guidance that helps the agent proactively do the things the user + often has to ask for repeatedly or avoid the kinds of overreach that trigger interruption. + +## What's in Memory + +This is a compact index to help future agents quickly find details in `MEMORY.md`, +`skills/`, and `rollout_summaries/`. +Treat it as a routing/index layer, not a mini-handbook: + +- tell future agents what to search first, +- preserve enough specificity to route into the right `MEMORY.md` block quickly. + +Topic selection and quality rules: + +- Organize the index first by project scope, then by topic. +- Split the index into a recent high-utility window and older topics. +- Do not target a fixed topic count. Include informative topics and omit low-signal noise. +- Prefer grouping by task family / workflow intent, not by incidental tool overlap alone. +- Order topics by utility, using `updated_at` recency as a strong default proxy unless there is + strong contrary evidence. +- Each topic bullet must include: topic, keywords, and a clear description. +- Keywords must be representative and directly searchable in `MEMORY.md`. + Prefer exact strings that a future agent can search for (project names, user query phrases, + tool names, error strings, commands, file paths, APIs/contracts). Avoid vague synonyms. +- Use a short project scope label that groups closely related tasks into one practical area. +- Use source-faithful topic labels and descriptions: + - prefer labels built from the rollout/task wording over newly invented abstract categories; + - prefer exact phrases from `description:`, `task:`, and user wording when those phrases are + already discriminative; + - if a combined topic must cover multiple rollouts, preserve at least a few original strings + from the underlying tasks so the abstraction does not erase retrieval handles. + +Required subsection structure (in this order): + +After the top-level sections `## User Profile`, `## User preferences`, and `## General Tips`, +structure `## What's in Memory` like this: + +### + +#### + +Recent Active Memory Window behavior (scope-first, then day-ordered): + +- Define a "memory day" as a calendar date (derived from `updated_at`) that has at least one + represented memory/rollout in the current memory set. +- Build the recent window from the most recent meaningful topics first, then group those topics + by their best project scope. +- Within each scope, order day subsections by recency. +- If a scope has only one meaningful recent day, include only that day for that scope. +- For each recent-day subsection inside a scope, prioritize informative, likely-to-recur topics and make + those entries richer (better keywords, clearer descriptions, and useful recent learnings); + do not spend much space on trivial tasks touched that day. +- Preserve routing coverage for `MEMORY.md` in the overall index.

Assistant summaries are secondary evidence about how the agent responded. +- Pure discussion, brainstorming, and tentative design talk should usually stay in the + rollout summary unless there is clear evidence that the conclusion held. + +============================================================ +HOW TO READ A ROLLOUT +============================================================ + +When deciding what to preserve, read the rollout in this order of importance: + +1. User messages + - strongest source for preferences, constraints, acceptance criteria, dissatisfaction, + and "what should have been anticipated" +2. Tool outputs / verification evidence + - strongest source for system facts, failures, commands, exact artifacts, and what actually worked +3. Assistant actions/messages + - useful for reconstructing what was attempted and how the user steered the agent, + but not the primary source of truth for user preferences + +What to look for in user messages: + +- repeated requests +- corrections to scope, naming, ordering, visibility, presentation, or editing behavior +- points where the user had to stop the agent, add missing specification, or ask for a redo +- requests that could plausibly have been anticipated by a stronger agent +- near-verbatim instructions that would be useful defaults in future runs + +General inference rule: + +- If the user spends keystrokes specifying something that a good future agent could have + inferred or volunteered, consider whether that should become a remembered default. + +============================================================ +EXAMPLES: USEFUL MEMORIES BY TASK TYPE +============================================================ + +Coding / debugging agents: + +- Project orientation: key directories, entrypoints, configs, structure, etc. +- Fast search strategy: where to grep first, what keywords worked, what did not. +- Common failure patterns: build/test errors and the proven fix. +- Stop rules: quickly validate success or detect wrong direction. +- Tool usage lessons: correct commands, flags, environment assumptions. + +Browsing/searching agents: + +- Query formulations and narrowing strategies that worked. +- Trust signals for sources; common traps (outdated pages, irrelevant results). +- Efficient verification steps (cross-check, sanity checks). + +Math/logic solving agents: + +- Key transforms/lemmas; “if looks like X, apply Y”. +- Typical pitfalls; minimal-check steps for correctness. + +============================================================ +TASK OUTCOME TRIAGE +============================================================ + +Before writing any artifacts, classify EACH task within the rollout. +Some rollouts only contain a single task; others are better divided into a few tasks. + +Outcome labels: + +- outcome = success: task completed / correct final result achieved +- outcome = partial: meaningful progress, but incomplete / unverified / workaround only +- outcome = uncertain: no clear success/failure signal from conversation evidence +- outcome = fail: task not completed, wrong result, stuck loop, tool misuse, or user dissatisfaction + +Rules: + +- Use the explicit `terminal_metadata` block from the user message as a first-class signal. +- Infer from conversation evidence using these heuristics and your best judgment. + +Terminal metadata guidance: + +- `completed` means the run ended with a final output, but individual tasks can still be + partial or uncertain if the evidence says so. +- `interrupted` means the run stopped for approvals or another resumable interruption. + Do not treat interruption as automatic failure; focus on what had or had not been + accomplished before the interruption. +- `cancelled` means the run was stopped before completion. Usually prefer `partial` or + `uncertain` unless there is strong contrary evidence. +- `failed`, `max_turns_exceeded`, and `guardrail_tripped` are strong negative signals for the + overall run outcome, but you should still preserve any reusable partial progress. + +Typical real-world signals (use as examples when analyzing the rollout): + +1. Explicit user feedback (obvious signal): + - Positive: "works", "this is good", "thanks" -> usually success. + - Negative: "this is wrong", "still broken", "not what I asked" -> fail or partial. +2. User proceeds and switches to the next task: + - If there is no unresolved blocker right before the switch, prior task is usually success. + - If unresolved errors/confusion remain, classify as partial (or fail if clearly broken). +3. User keeps iterating on the same task: + - Requests for fixes/revisions on the same artifact usually mean partial, not success. + - Requesting a restart or pointing out contradictions often indicates fail. + - Repeated follow-up steering is also a strong signal about user preferences, + expected workflow, or dissatisfaction with the current approach. +4. Last task in the rollout: + - Treat the final task more conservatively than earlier tasks. + - If there is no explicit user feedback or environment validation for the final task, + prefer `uncertain` (or `partial` if there was obvious progress but no confirmation). + - For non-final tasks, switching to another task without unresolved blockers is a stronger + positive signal. + +Signal priority: + +- Explicit user feedback and explicit environment/test/tool validation outrank all heuristics. +- If heuristic signals conflict with explicit feedback, follow explicit feedback. + +Fallback heuristics: + +- Success: explicit "done/works", tests pass, correct artifact produced, user + confirms, error resolved, or user moves on after a verified step. +- Fail: repeated loops, unresolved errors, tool failures without recovery, + contradictions unresolved, user rejects result, no deliverable. +- Partial: incomplete deliverable, "might work", unverified claims, unresolved edge + cases, or only rough guidance when concrete output was required. +- Uncertain: no clear signal, or only the assistant claims success without validation. + +Additional preference/failure heuristics: + +- If the user has to repeat the same instruction or correction multiple times, treat that + as high-signal preference evidence. +- If the user discards, deletes, or asks to redo an artifact, do not treat the earlier + attempt as a clean success. +- If the user interrupts because the agent overreached or failed to provide something the + user predictably cares about, preserve that as a workflow preference when it seems likely + to recur. +- If the user spends extra keystrokes specifying something the agent could reasonably have + anticipated, consider whether that should become a future default behavior. + +This classification should guide what you write. If fail/partial/uncertain, emphasize +what did not work, pivots, and prevention rules, and write less about +reproduction/efficiency. Omit any section that does not make sense. + +============================================================ +DELIVERABLES +============================================================ + +Return exactly one JSON object with required keys: + +- `rollout_summary` (string) +- `rollout_slug` (string) +- `raw_memory` (string) + +`rollout_summary` and `raw_memory` formats are below. `rollout_slug` is a +filesystem-safe stable slug to best describe the rollout (lowercase, hyphen/underscore, <= 80 chars). + +Rules: + +- Empty-field no-op must use empty strings for all three fields. +- No additional keys. +- No prose outside JSON. + +============================================================ +`rollout_summary` FORMAT +============================================================ + +Goal: distill the rollout into useful information, so that future agents usually don't need to +reopen the raw rollouts. +You should imagine that the future agent can fully understand the user's intent and +reproduce the rollout from this summary. +This summary can be comprehensive and detailed, because it may later be used as a reference +artifact when a future agent wants to revisit or execute what was discussed. +There is no strict size limit, and you should feel free to list a lot of points here as +long as they are helpful. +Do not target fixed counts (tasks, bullets, references, or topics). Let the rollout's +signal density decide how much to write. +Instructional notes in angle brackets are guidance only; do not include them verbatim in the rollout summary. + +Important judgment rules: + +- Rollout summaries may be more permissive than durable memory, because they are reference + artifacts for future agents who may want to execute or revisit what was discussed. +- The rollout summary should preserve enough evidence and nuance that a future agent can see + how a conclusion was reached, not just the conclusion itself. +- Preserve epistemic status when it matters. Make it clear whether something was verified + from code/tool evidence, explicitly stated by the user, inferred from repeated user + behavior, proposed by the assistant and accepted by the user, or merely proposed / + discussed without clear adoption. +- Overindex on user messages and user-side steering when deciding what is durable. Underindex on + assistant messages, especially in brainstorming, design, or naming discussions where the + assistant may be proposing options rather than recording settled facts. +- Prefer epistemically honest phrasing such as "the user said ...", "the user repeatedly + asked ... indicating ...", "the assistant proposed ...", or "the user agreed to ..." + instead of rewriting those as unattributed facts. +- When a conclusion is abstract, prefer an evidence -> implication -> future action shape: + what the user did or asked for, what that suggests about their preference, and what future + agents should proactively do differently. +- Prefer concrete evidence before abstraction. If a lesson comes from what the user asked + the agent to do, show enough of the specific user steering to give context, for example: + "the user asked to ... indicating that ..." +- Do not over-index on exploratory discussions or brainstorming sessions because these can + change quickly, especially when they are single-turn. Especially do not write down + assistant messages from pure discussions as durable memory. If a discussion carries any + weight, it should usually be framed as "the user asked about ..." rather than "X is true." + These discussions often do not indicate long-term preferences. + +Use an explicit task-first structure for rollout summaries. + +- Do not write a rollout-level `User preferences` section. +- Preference evidence should live inside the task where it was revealed. +- Use the same task skeleton for every task in the rollout; omit a subsection only when it is truly empty. + +Template: + +# + +Rollout context: + + + +## Task : + +Outcome: + +Preference signals: + +- Preserve quote-like evidence when possible. +- Prefer an evidence -> implication shape on the same bullet: + - when , the user said / asked / corrected: "" -> what that suggests they want by default (without prompting) in similar situations +- Repeated follow-up corrections, redo requests, interruption patterns, or repeated asks for + the same kind of output are often the highest-value signal in the rollout. + - if the user interrupts, this may indicate they want more clarification, control, or discussion + before the agent takes action in similar situations + - if the user prompts the logical next step without much extra specification, such as + "address the feedback", "go ahead and publish this", "now write the summary", + or "use the same naming pattern as before", this may indicate a default the agent should + have anticipated without being prompted +- Preserve near-verbatim user requests when they are reusable operating instructions. +- Keep the implication only as broad as the evidence supports. +- Split distinct preference signals into separate bullets when they would change different future + defaults. Do not merge several concrete requests into one vague umbrella preference. +- Good examples: + - after the agent hit a validation failure, the user asked the agent to + "explain what failed and propose a fix before changing anything" -> + this suggests that when validation fails, the user wants the agent to diagnose first + and propose a fix before editing. + - after the agent only preserved a final answer, the user asked for the surrounding context + and failure details to be included -> this suggests the user wants enough context to inspect + failures directly, not just the final output. + - after the agent named artifacts by broad topic, the user renamed or asked to rename + them by the behavior being validated -> this suggests the user prefers artifact names that + encode what is being validated, not just the topic area. +- If there is no meaningful preference evidence for this task, omit this subsection. + +Key steps: + +- (optional evidence refs: [1], [2], + ...) +- Keep this section concise unless the steps themselves are highly reusable.
