* Python: [BREAKING] Make all SkillsProvider tools require approval by default All tools exposed by SkillsProvider (load_skill, read_skill_resource, run_skill_script) now require approval by default. Previously only run_skill_script could be gated, and only when require_script_approval=True. - Register all three tools with approval_mode="always_require" - Add read_only_tools_auto_approval_rule and all_tools_auto_approval_rule static rules plus tool-name constants (mirrors FileAccessProvider) - Remove the require_script_approval option from __init__ and from_paths - Add skills_auto_approval sample; update script_approval sample/docs Closes #6728 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: batch skill approval responses and tidy sample - Collect a response for every approval request and send them in a single agent.run so the approval loop always makes progress (no infinite loop when a request lacks a function_call); reject non-function requests instead of skipping them. Applied to both the skills_auto_approval and script_approval samples. - Extract ToolApprovalMiddleware into a local variable in skills_auto_approval for readability. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: add approval handling to remaining skills samples The secure-by-default change makes all SkillsProvider tools require approval, which left the other skills samples emitting approval requests instead of the documented answers. Add ToolApprovalMiddleware with the all-tools auto-approval rule (and a session, which the middleware requires) so these samples run unattended as before: - code_defined_skill, file_based_skill, class_based_skill, mixed_skills, skill_filtering, mcp_based_skill - providers/foundry/foundry_chat_client_with_toolbox_skills The dedicated script_approval (manual) and skills_auto_approval (selective) samples continue to demonstrate interactive approval handling. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: simplify "host approval" wording to "approval" Apply maintainer suggestions dropping "host" from the skill-approval docstrings, and align the matching SkillsProvider docstring/AGENTS.md note for consistency.

Prerequisites
pip install agent-framework
Environment Variables
Samples call load_dotenv() to automatically load environment variables from a .env file in the python/ directory. This is a convenience for local development and testing.
For local development, set up your environment using any of these methods:
Option 1: Using a .env file (recommended for local development):
- Copy
.env.exampleto.envin thepython/directory:cp .env.example .env - Edit
.envand set your values (API keys, endpoints, etc.)
Option 2: Export environment variables directly:
export FOUNDRY_PROJECT_ENDPOINT="your-foundry-project-endpoint"
export FOUNDRY_MODEL="gpt-4o"
Option 3: Using env_file_path parameter (for per-client configuration):
All client classes (e.g., OpenAIChatClient, OpenAIChatCompletionClient) support an env_file_path parameter to load environment variables from a specific file:
from agent_framework.openai import OpenAIChatClient
# Load from a custom .env file
client = OpenAIChatClient(env_file_path="path/to/custom.env")
This allows different clients to use different configuration files if needed.
For the generic OpenAI clients (OpenAIChatClient and OpenAIChatCompletionClient), routing
precedence is:
- Explicit Azure inputs such as
credential,azure_endpoint, orapi_version OPENAI_API_KEY/ explicit OpenAI API-key parameters- Azure environment fallback such as
AZURE_OPENAI_ENDPOINTandAZURE_OPENAI_API_KEY
If you keep both OpenAI and Azure variables in your shell, the generic clients stay on OpenAI until you pass an explicit Azure input.
For the getting-started samples, you'll need at minimum:
FOUNDRY_PROJECT_ENDPOINT="your-foundry-project-endpoint"
FOUNDRY_MODEL="gpt-4o"
Consolidated sample env inventory
This is the single source of truth for package-level environment variables read by packages included by
agent-framework-core[all]. It intentionally excludes variables that are only read by standalone samples,
package sample folders, or tests. When package code adds, removes, or renames an environment variable,
update this table in the same change.
Example values below are illustrative. For entries not backed by a single public class, the class
column names the closest public surface, helper, or package-level initialization point that reads the
variable.

agent-framework-openai supports the Azure OpenAI client-specific deployment aliases listed above; keep
packages/openai/README.md as the authoritative reference for the exact fallback order and package-specific
behavior.
Note for production: In production environments, set environment variables through your deployment platform (e.g., Azure App Settings, Kubernetes ConfigMaps/Secrets) rather than using .env files. The load_dotenv() call in samples will have no effect when a .env file is not present, allowing environment variables to be loaded from the system.
For Azure authentication, run az login before running samples.
Note on XML tags
Some sample files include XML-style snippet tags (for example <snippet_name> and </snippet_name>). These are used by our documentation tooling and can be ignored or removed when you use the samples outside this repository.
