* Reorganize A2A samples: client demos in 02-agents, use package A2AExecutor
- Move client samples (agent_with_a2a, a2a_agent_as_function_tools) to samples/02-agents/a2a/
- Add new concept samples: polling, stream reconnection, protocol selection
- Replace sample agent_executor.py with package-level A2AExecutor (stream=True)
- Update 04-hosting/a2a to focus on server-side, point to 02-agents for clients
- Add README.md for the new 02-agents/a2a/ sample collection

* Fix streaming artifact coalescing and address PR review feedback
A2AExecutor fix:
- Generate a stable artifact_id per stream in _run_stream so all streaming
chunks share the same ID, enabling proper append=True coalescing per the
A2A spec (TaskArtifactUpdateEvent with same artifactId).
- Previously, item.message_id was None for OpenAI/Foundry streaming updates,
causing the SDK to generate a new random UUID per token (100+ separate
artifacts instead of 1 appended artifact).
Sample improvements:
- Replace join workaround with response.text now that coalescing works
- Add background=True to stream reconnection resume call (required for
continuation token emission on in-progress tasks)
- Fix type ignore specificity in polling sample

* Add requirements.txt and .env.example to a2a sample
Beginners following the a2a/ sample had no pip-based install path:
the directory lacked requirements.txt and .env.example, unlike every
other 04-hosting/ sample.
- Add requirements.txt with editable local package paths matching the
pattern used in azure_functions/ and similar hosting samples
- Add .env.example documenting FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL,
and A2A_AGENT_HOST
- Update README Quick Start to cover both pip (.venv) and uv workflows

* Python: Add `requirements.txt` and `.env.example` to the `a2a/` sample for pip-based setup
Fixes#5395
* fix(a2a-sample): address PR review feedback for issue #5395
- Remove 'from repo root' wording from Option B uv heading in README
to avoid contradicting the 'run from this directory' instruction
- Fix A2A_AGENT_HOST default in .env.example from 5001 to 5000 to match
function-tools flow; add clarifying comments about port usage
- Add note for pip users explaining they can replace 'uv run python'
with 'python' once the virtual environment is activated

* Add Python A2A agent-as-function-tools sample
Port of the .NET A2AAgent_AsFunctionTools sample to Python.
Resolves a remote A2A agent card, converts each skill to a
FunctionTool via as_tool(), and registers them with a host agent
using AzureOpenAIResponsesClient.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Sanitize A2A skill names before passing to as_tool()
as_tool() only auto-sanitizes when name is omitted. Since we pass
skill.name explicitly, we need to strip special characters ourselves.

* Python: Add A2A server sample and fix client streaming bug
Add a pure Python A2A server sample so testing the A2A client no longer
requires running the .NET server. The server uses the a2a-sdk's
A2AStarletteApplication with uvicorn and supports three agent types
(invoice, policy, logistics) backed by AzureOpenAIResponsesClient.
New files:
- a2a_server.py: Main server entry point with CLI args
- agent_executor.py: Bridges a2a-sdk AgentExecutor to Agent Framework
- agent_definitions.py: Agent and AgentCard factory definitions
- invoice_data.py: Mock invoice data and query tool functions
- a2a_server.http: REST Client requests for testing
Also fixes a streaming bug in agent_with_a2a.py where async with was
used on ResponseStream which does not support the async context manager
protocol. Changed to async for to match all other samples.
Closes#4045

* Address PR review: handle CancelledError and fix end_date filtering
- Re-raise asyncio.CancelledError before the broad exception handler
so cooperative cancellation is not swallowed.
- Make end_date filter inclusive of the full day by comparing with
< end + timedelta(days=1) instead of <= midnight.

* restructure: Python samples into progressive 01-05 layout
- 01-get-started/: 6 numbered steps (hello agent → hosting)
- 02-agents/: all agent concept samples (tools, middleware, providers, etc.)
- 03-workflows/: ALL existing workflow samples preserved as-is
- 04-hosting/: azure-functions, durabletask, a2a
- 05-end-to-end/: demos, evaluation, hosted agents
- Old files moved to _to_delete/ for review
- Added AGENTS.md with structure documentation
- autogen-migration/ and semantic-kernel-migration/ preserved at root
* fix: switch to AzureOpenAI Foundry, fix CI failures
- Switch all 01-get-started samples to AzureOpenAIResponsesClient with
Azure AI Foundry project endpoint (AZURE_AI_PROJECT_ENDPOINT +
AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME + AzureCliCredential)
- Add _to_delete/ and 05-end-to-end/ to pyrightconfig.samples.json excludes
- Fix test paths in packages/ that referenced old getting_started/ dirs:
durabletask conftest + streaming test, azurefunctions conftest,
devui conftest + capture_messages + openai_sdk_integration
- Fix workflow_as_agent_human_in_the_loop.py import (sibling import)
- Update hosting READMEs and tool comment paths
- Replace root README.md with new structure overview
- Update AGENTS.md to document Azure OpenAI Foundry as default provider
* cleanup: remove _to_delete folder, copy resource files to active dirs

- Exact duplicates of files in the new structure (240 files)
- Same file with only comment path updates (100 files)
- One import-fix diff (workflow_as_agent_human_in_the_loop.py)
- One superseded minimal_sample.py
Resource files (sample.pdf, countries.json, employees.pdf, weather.json)
copied to 02-agents/sample_assets/ and 02-agents/resources/ since active
samples reference them.
* fix: address PR review comments, centralize resources, remove root duplicates

02-agents/, 03-workflows/, 04-hosting/, 05-end-to-end/
- Fix absolute GitHub URLs in package READMEs
- Fix broken link in ollama package README
* fix: convert absolute GitHub URLs to relative paths for link checker
Absolute URLs to python/samples/ on main branch 404 until PR merges.
Converted to relative paths that linkspector can verify locally.
* fix: update link for handoff sample moved to orchestrations/
* fix: update chatkit-integration README path from demos/ to 05-end-to-end/
* fix: update broken links in orchestrations README to match flat directory structure
