* [BREAKING] Refactor middleware layering and raw clients Reorder chat client layers so function invocation wraps chat middleware, and chat middleware stays outside telemetry while still running for each inner model call. Add middleware pipeline caching, refresh docs and samples, and split Anthropic into raw and public clients to match the standard layering model. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Tighten typing ignores in ancillary modules Add targeted typing ignores in workflow visualization and lab modules so pyright stays clean alongside the middleware refactor work. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix categorize_middleware to unpack tuple/Sequence and use relative MRO assertions - Broaden isinstance check in categorize_middleware from list to Sequence so tuples and other Sequence types are properly unpacked instead of being appended as a single item. - Replace fragile hardcoded MRO index assertions in anthropic test with relative ordering via mro.index(). - Add regression tests for categorize_middleware with tuple, list, and None inputs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix middleware string decomposition, add middleware param to FunctionInvocationLayer, and add tests (#4710) - Guard categorize_middleware Sequence check against str/bytes to prevent character-by-character decomposition of accidentally passed strings - Add explicit middleware parameter to FunctionInvocationLayer.get_response and merge it into client_kwargs before categorization, fixing the inconsistency where only OpenAIChatClient supported this parameter - Add assertions that RawAnthropicClient does not inherit convenience layers - Add chat middleware cache test with non-empty base middleware - Add tests for single unwrapped middleware item and string input Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Apply pre-commit auto-fixes * Apply pre-commit auto-fixes * Address review feedback for #4710: review comment fixes --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Copilot <copilot@github.com>
Agent Framework Lab
This is the experimental package for Microsoft Agent Framework, agent-framework-lab, which contains
various lab modules built on top of the core framework.
Lab modules are not part of the core framework and may experience breaking changes or be deprecated in the future.
What are Lab Modules?
Lab modules are extensions to the core Agent Framework that fall into one of the following categories:
- Incubation of new features that may get incorporated by the core framework.
- Research prototypes built on the core framework.
- Benchmarks and experimentation tools.
Lab Modules
- gaia: Evaluate your agents using the GAIA benchmark for general assistant tasks
- tau2: Evaluate your agents using the TAU2 benchmark for customer support tasks
- lightning: RL training for agents using Agent Lightning

This structure maintains a single PyPI package agent-framework-lab while supporting modular imports through the namespace package mechanism.
Installation
To install each lab module, use the extras syntax with pip:
pip install "agent-framework-lab[gaia]"
pip install "agent-framework-lab[tau2]"
pip install "agent-framework-lab[lightning]"
Usage
Import and use lab modules from the agent_framework.lab namespace.
For example, to use the GAIA module:
# Using GAIA module
from agent_framework.lab.gaia import GAIA
Running Tests Locally
For machine-safe local runs, prefer package-scoped commands first:
uv run --directory packages/lab poe test
uv run --directory packages/lab pytest -q -m "not integration"
When you need to run lab tests from the repository root, scope the root task to the lab package:
uv run poe test -P lab
Lightning observability tests intentionally exercise heavier tracing paths and are marked as resource_intensive:
uv run --directory packages/lab pytest lightning/tests/test_lightning.py -m "resource_intensive" -q
Should I consume Lab Modules?
If you are looking for stable and production-ready features, you should not use lab modules. Stick to the core framework.
If you are looking for experimentation, research, or want to benchmark different approaches -- most importantly, if you don't mind breaking changes and potential deprecations -- then lab modules are for you.
Contributing to Lab Modules
Microsoft-maintained modules
For Microsoft-maintained modules in this repository, please follow standard contribution guidelines and submit pull requests directly to this repository.
Community modules
If you want to contribute a community-maintained lab module:
- Create a new repository on GitHub for your module
- Tag your repository with
agent-framework-labfor discoverability - Submit a PR to add a link to your repository in the Lab Modules section above
- Use the PR title format:
[New Lab Module] Your Module Name
We will review your submission based on the guidelines below.
Guidelines
- Purpose: Community modules should fit into one of the three categories of lab modules (incubation, research, benchmarks)
- Namespace: Community modules should avoid the
agent_framework.labnamespace (reserved for modules maintained in this repository) - Dependencies: Minimize external dependencies, always include
agent-frameworkas a base dependency - Documentation: Include comprehensive README with installation instructions and usage examples
- Tests: Write comprehensive tests with good coverage
- Type hints: Always include type hints and a
py.typedfile - Versioning: Use semantic versioning, start with
0.1.0for initial releases
