Evan Mattson c67372ff32 Python: [BREAKING]: Canonicalize AG-UI interrupt and resume handling (#6925)
* Python: Emit AG-UI interrupt outcomes

Key decisions: raise ag-ui-protocol to 0.1.19, type AGUIRequest/AGUIChatOptions with protocol Interrupt and ResumeEntry, and emit interrupted runs through RUN_FINISHED.outcome.interrupts instead of the legacy top-level interrupt field. Preserve existing internal resume/snapshot compatibility by translating legacy interruption metadata into canonical Interrupt metadata.

Files changed: packages/ag-ui pyproject, AG-UI run/type/workflow/snapshot helpers, AG-UI protocol-shape tests, and uv.lock.

Verification: uv run poe test -P ag-ui; uv run poe syntax -P ag-ui -C; uv run poe typing -P ag-ui; uv run poe validate-dependency-bounds-test -P ag-ui; uv run poe check -P ag-ui; git diff --cached --check.

Notes: README and local PRD/Ralph planning files were left unstaged. Follow-up slices still own richer approval/workflow response schemas and full client-side resume forwarding.

* Python: Emit canonical AG-UI approval interrupts

Key decisions: build Agent Framework approval pauses as canonical AG-UI Interrupt entries under RUN_FINISHED.outcome.interrupts; use reason=tool_call with toolCallId routing; advertise generic approval response schemas using the existing accepted/edited-argument payload contract; keep legacy Agent Framework approval metadata nested under metadata.agent_framework.value for internal snapshot/resume compatibility while avoiding any top-level interrupt value in emitted protocol JSON.

Files changed: packages/ag-ui/agent_framework_ag_ui/_run_common.py adds canonical approval interrupt/schema helpers and uses them for function approval requests; packages/ag-ui/agent_framework_ag_ui/_agent_run.py emits canonical interrupts for predictive confirm_changes pauses; packages/ag-ui/tests/ag_ui/test_endpoint.py covers endpoint/SSE approval pause shape; packages/ag-ui/tests/ag_ui/test_run.py covers helper and run-level confirmation interrupt behavior.

Notes: local README, PRD, .ralph, and issue planning artifacts remain unstaged. Follow-up slices still own canonical ResumeEntry approval continuation, workflow request_info canonical resume, client-side forwarding, pending interrupt contract enforcement, snapshot stale-prompt clearing, and documentation/examples.

* Python: Resume AG-UI approvals canonically

Key decisions: translate canonical ResumeEntry approval payloads into the existing Agent Framework function approval response path at the AG-UI agent-run boundary; route by canonical interruptId while preserving pending approval registry validation; allow edited arguments only through canonical resume translation by updating the stored pending argument fingerprint before execution; emit RUN_ERROR for cancelled, unknown, or malformed approval resumes instead of proceeding.

Files changed: packages/ag-ui/agent_framework_ag_ui/_agent_run.py adds canonical approval resume translation, interrupt-id registry aliasing, explicit approval resume RUN_ERROR handling, and alias cleanup on consumption; packages/ag-ui/tests/ag_ui/test_endpoint.py adds endpoint/SSE coverage for approved, denied, edited, cancelled, and unknown canonical approval resumes.

Notes: issues/agui-int-03-agent-approval-resume-entry.md was moved to issues/done locally but remains unstaged. Existing local README, PRD, and .ralph artifacts remain unstaged. Follow-up slices still own workflow request_info canonical resume, client-side forwarding, stricter pending interrupt contract enforcement, snapshot stale-prompt clearing, and documentation/examples.

* Python: Resume workflow interrupts canonically

Key decisions: emit workflow request_info pauses as canonical input_required interrupt outcomes with response schemas and Agent Framework metadata; normalize typed ResumeEntry model dumps through the shared resume parser while preserving status; translate resolved workflow resume payloads through the existing workflow response coercion path; emit RUN_ERROR for cancelled workflow resumes before invoking the workflow.

Files changed: packages/ag-ui/agent_framework_ag_ui/_run_common.py preserves canonical resume status/model dumps and merges interrupt metadata values; packages/ag-ui/agent_framework_ag_ui/_workflow_run.py builds canonical workflow request_info interrupts and cancellation errors; packages/ag-ui/tests/ag_ui/test_endpoint.py adds endpoint/SSE workflow pause, resolved resume, and cancelled resume coverage; packages/ag-ui/tests/ag_ui/test_run_common.py and packages/ag-ui/tests/ag_ui/test_workflow_run.py update canonical helper expectations.

Notes: issue bookkeeping and local PRD files were not staged; existing unstaged packages/ag-ui/README.md remains untouched. Follow-up slices still own client-side forwarding, stricter pending interrupt contract enforcement, snapshot stale-prompt clearing, and documentation/examples.

* Python: Forward AG-UI interrupts through client

Key decisions: normalize typed Interrupt and ResumeEntry values at the AGUIChatClient and AGUIHttpService boundaries using protocol aliases; map legacy request_info available-interrupt hints to canonical input_required reason while preserving legacy resume wrapper shapes; preserve remote RUN_FINISHED.outcome metadata and expose outcome.interrupts for Agent Framework callers without changing normal success completion handling.

Files changed: packages/ag-ui/agent_framework_ag_ui/_client.py forwards normalized available_interrupts/resume values; packages/ag-ui/agent_framework_ag_ui/_http_service.py serializes typed protocol models and compatible values to camelCase wire JSON; packages/ag-ui/agent_framework_ag_ui/_event_converters.py preserves canonical outcomes/interruption metadata; packages/ag-ui/tests/ag_ui/test_ag_ui_client.py, test_http_service.py, and test_event_converters.py cover outgoing typed JSON, canonical interrupted conversion, and success outcome behavior.

Notes: issues/agui-int-05-chat-client-http-forwarding.md was moved to issues/done locally but not staged. Existing unstaged packages/ag-ui/README.md, .ralph, PRD, and snapshot planning artifacts remain untouched. Follow-up slices still own stricter pending interrupt contract enforcement, snapshot stale-prompt clearing, and documentation/examples.

* Python: Enforce AG-UI resume contract

Key decisions: validate pending AG-UI interrupts before agent or workflow execution; require resume entries to address every open interrupt exactly once; emit RUN_ERROR for missing, unknown, duplicate, malformed, cancelled, or schema-invalid resume payloads; keep successful canonical approval and workflow resume flows working while removing heuristic non-resume workflow continuation for interrupted threads.

Files changed: packages/ag-ui/agent_framework_ag_ui/_run_common.py adds strict resume parsing and exact pending-interrupt contract validation; _agent_run.py applies the contract to approval resumes, validates edited approval argument types, and considers stored canonical interrupt ids; _workflow_run.py applies the contract to request_info resumes and fails invalid response coercion explicitly; AG-UI endpoint, workflow, golden, wrapper, and subgraph tests now cover RUN_ERROR failures and canonical resume entries.

Notes: issues/agui-int-06-resume-contract-validation.md was moved to issues/done locally but not staged. Existing unstaged packages/ag-ui/README.md and local .ralph/PRD artifacts remain untouched. Follow-up slices still own canonical snapshot stale-prompt clearing and documentation/examples.

* Python: Clear AG-UI snapshot interrupts on cancel

Key decisions: treat cancelled canonical approval and workflow resumes as completion of the stored interruption for AG-UI Thread Snapshot hydration; clear only the persisted interrupt field while preserving replayable messages and Shared State; consume cancelled approval registry entries so server-side approval state does not remain open; preserve existing RUN_ERROR responses for cancelled resumes.

Files changed: packages/ag-ui/agent_framework_ag_ui/_snapshots.py adds shared persisted-interrupt clearing; _agent_run.py clears snapshots and consumes pending approvals on cancelled approval resumes; _workflow.py clears snapshots on cancelled workflow resumes; test_endpoint.py covers agent/workflow cancelled-resume stale prompt clearing; test_run_common.py covers canonical interrupt toolCallId trusted suffix filtering.

Verification: uv run pytest focused interrupted snapshot/resume tests -q; uv run poe test -P ag-ui; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; uv run poe typing -P ag-ui; uv run poe check -P ag-ui; git diff --check; git diff --cached --check.

Notes: issues/agui-int-07-thread-snapshot-interrupt-hydration.md was moved to issues/done locally but not staged. Existing unstaged packages/ag-ui/README.md and local .ralph/PRD artifacts remain untouched. Follow-up docs/examples slice still owns public guidance updates.

* Python: Document canonical AG-UI interrupts

Key decisions: document the clean release-candidate interrupt cutover around canonical AG-UI protocol models; direct users to RUN_FINISHED.outcome.interrupts and canonical resume arrays; make clear that Interrupt and ResumeEntry come from ag_ui.core rather than an Agent Framework-specific model; retain normal RUN_FINISHED completion guidance for non-interrupted runs.

Files changed: packages/ag-ui/AGENTS.md updates package guidance; packages/ag-ui/README.md adds interrupt/resume protocol and migration notes; packages/ag-ui/agent_framework_ag_ui_examples/README.md documents canonical resume shape for examples; packages/ag-ui/getting_started/README.md teaches outcome.interrupts and ResumeEntry usage.

Verification: uv run poe markdown-code-lint failed on pre-existing packages/mistral/README.md; uv run python scripts/check_md_code_blocks.py packages/ag-ui/README.md packages/ag-ui/agent_framework_ag_ui_examples/README.md packages/ag-ui/getting_started/README.md packages/ag-ui/AGENTS.md; git diff --check; git diff --cached --check.

Notes: no issue or PRD artifacts were staged. Root AGENTS.md could not be read because access was denied; package and Python workspace guidance were applied. Follow-up docs/examples issue appears complete; no remaining AG-UI interrupt cutover tasks were found locally.

Get Started with Microsoft Agent Framework for Python Developers

Quick Install

We recommend two common installation paths depending on your use case.

1. Development mode

If you are exploring or developing locally, install the entire framework with all sub-packages:

pip install agent-framework

This installs the core and every integration package, making sure that all features are available without additional steps. This is the simplest way to get started.

2. Selective install

If you only need specific integrations, you can install at a more granular level. This keeps dependencies lighter and focuses on what you actually plan to use. Some examples:

# Core only
# includes Azure OpenAI and OpenAI support by default
# also includes workflows and orchestrations
pip install agent-framework-core

# Core + Azure AI Foundry integration
pip install agent-framework-foundry

# Core + Microsoft Copilot Studio integration (preview package)
pip install agent-framework-copilotstudio --pre

# Core + both Microsoft Copilot Studio and Azure AI Foundry integration
pip install --pre agent-framework-copilotstudio agent-framework-foundry

This selective approach is useful when you know which integrations you need, and it is the recommended way to set up lightweight environments. Released packages such as agent-framework, agent-framework-core, and agent-framework-foundry no longer require --pre, while preview connectors such as agent-framework-copilotstudio still do.

Supported Platforms:

  • Python: 3.10+
  • OS: Windows, macOS, Linux

1. Setup API Keys

Set as environment variables, or create a .env file at your project root:

OPENAI_API_KEY=sk-...
OPENAI_MODEL=...
...
AZURE_OPENAI_API_KEY=...
AZURE_OPENAI_ENDPOINT=...
AZURE_OPENAI_MODEL=...
...
FOUNDRY_PROJECT_ENDPOINT=...
FOUNDRY_MODEL=...

For the generic OpenAI clients (OpenAIChatClient and OpenAIChatCompletionClient), configuration resolves in this order:

  1. Explicit Azure inputs such as credential or azure_endpoint
  2. OPENAI_API_KEY / explicit OpenAI API-key parameters
  3. Azure environment fallback such as AZURE_OPENAI_ENDPOINT and AZURE_OPENAI_API_KEY

This means mixed shells default to OpenAI when OPENAI_API_KEY is present. To force Azure routing, pass an explicit Azure input such as credential=AzureCliCredential().

You can also override environment variables by explicitly passing configuration parameters to the chat client constructor:

from agent_framework.openai import OpenAIChatClient

client = OpenAIChatClient(
    api_key='',
    azure_endpoint='',
    model='',
    api_version='',
)

See the following setup guide for more information.

2. Create a Simple Agent

Create agents and invoke them directly:

import asyncio
from agent_framework import Agent
from agent_framework.openai import OpenAIChatClient

async def main():
    agent = Agent(
        client=OpenAIChatClient(),
        instructions="""
        1) A robot may not injure a human being...
        2) A robot must obey orders given it by human beings...
        3) A robot must protect its own existence...

        Give me the TLDR in exactly 5 words.
        """
    )

    result = await agent.run("Summarize the Three Laws of Robotics")
    print(result)

asyncio.run(main())
# Output: Protect humans, obey, self-preserve, prioritized.

3. Directly Use Chat Clients (No Agent Required)

You can use the chat client classes directly for advanced workflows:

import asyncio
from agent_framework import Message
from agent_framework.openai import OpenAIChatClient

async def main():
    client = OpenAIChatClient()

    messages = [
        Message("system", ["You are a helpful assistant."]),
        Message("user", ["Write a haiku about Agent Framework."])
    ]

    response = await client.get_response(messages)
    print(response.messages[0].text)

    """
    Output:

    Agents work in sync,
    Framework threads through each task—
    Code sparks collaboration.
    """

asyncio.run(main())

4. Build an Agent with Tools and Functions

Enhance your agent with custom tools and function calling:

import asyncio
from typing import Annotated
from random import randint
from pydantic import Field
from agent_framework import Agent
from agent_framework.openai import OpenAIChatClient


def get_weather(
    location: Annotated[str, Field(description="The location to get the weather for.")],
) -> str:
    """Get the weather for a given location."""
    conditions = ["sunny", "cloudy", "rainy", "stormy"]
    return f"The weather in {location} is {conditions[randint(0, 3)]} with a high of {randint(10, 30)}°C."


def get_menu_specials() -> str:
    """Get today's menu specials."""
    return """
    Special Soup: Clam Chowder
    Special Salad: Cobb Salad
    Special Drink: Chai Tea
    """


async def main():
    agent = Agent(
        client=OpenAIChatClient(),
        instructions="You are a helpful assistant that can provide weather and restaurant information.",
        tools=[get_weather, get_menu_specials]
    )

    response = await agent.run("What's the weather in Amsterdam and what are today's specials?")
    print(response)

    """
    Output:
    The weather in Amsterdam is sunny with a high of 22°C. Today's specials include
    Clam Chowder soup, Cobb Salad, and Chai Tea as the special drink.
    """

if __name__ == "__main__":
    asyncio.run(main())

You can explore additional agent samples here.

5. Multi-Agent Orchestration

Coordinate multiple agents to collaborate on complex tasks using orchestration patterns:

import asyncio
from agent_framework import Agent
from agent_framework.openai import OpenAIChatClient


async def main():
    # Create specialized agents
    writer = Agent(
        client=OpenAIChatClient(),
        name="Writer",
        instructions="You are a creative content writer. Generate and refine slogans based on feedback."
    )

    reviewer = Agent(
        client=OpenAIChatClient(),
        name="Reviewer",
        instructions="You are a critical reviewer. Provide detailed feedback on proposed slogans."
    )

    # Sequential workflow: Writer creates, Reviewer provides feedback
    task = "Create a slogan for a new electric SUV that is affordable and fun to drive."

    # Step 1: Writer creates initial slogan
    initial_result = await writer.run(task)
    print(f"Writer: {initial_result}")

    # Step 2: Reviewer provides feedback
    feedback_request = f"Please review this slogan: {initial_result}"
    feedback = await reviewer.run(feedback_request)
    print(f"Reviewer: {feedback}")

    # Step 3: Writer refines based on feedback
    refinement_request = f"Please refine this slogan based on the feedback: {initial_result}\nFeedback: {feedback}"
    final_result = await writer.run(refinement_request)
    print(f"Final Slogan: {final_result}")

    # Example Output:
    # Writer: "Charge Forward: Affordable Adventure Awaits!"
    # Reviewer: "Good energy, but 'Charge Forward' is overused in EV marketing..."
    # Final Slogan: "Power Up Your Adventure: Premium Feel, Smart Price!"

if __name__ == "__main__":
    asyncio.run(main())

For more advanced orchestration patterns including Sequential, Concurrent, Group Chat, Handoff, and Magentic orchestrations, see the orchestration samples.
