description	Code quality checks, linting, formatting, and type checking commands for the Agent Framework Python codebase. Use this when running checks, fixing lint errors, or troubleshooting CI failures.

Python Code Quality

Quick Commands

All commands run from the python/ directory:

# Syntax formatting + checks (parallel across packages by default)
uv run poe syntax
uv run poe syntax -P core
uv run poe syntax -F    # Format only
uv run poe syntax -C    # Check only
uv run poe syntax -S    # Samples only

# Type checking
uv run poe pyright       # Pyright fan-out across packages
uv run poe pyright -P core
uv run poe pyright -A
uv run poe mypy          # MyPy fan-out across packages
uv run poe mypy -P core
uv run poe mypy -A
uv run poe typing        # Both pyright and mypy
uv run poe typing -P core
uv run poe typing -A

# All package-level checks in parallel (syntax + pyright)
uv run poe check-packages

# Full check (packages + samples + tests + markdown)
uv run poe check
uv run poe check -P core

# Samples only
uv run poe check -S
uv run poe pyright -S

# Markdown code blocks
uv run poe markdown-code-lint

Pre-commit Hooks (prek)

Prek hooks run automatically on commit. They stay lightweight and only check changed files.

# Install hooks
uv run poe prek-install

# Run all hooks manually
uv run prek run -a

# Run on last commit
uv run prek run --last-commit

They run changed-package syntax formatting/checking, markdown code lint only when markdown files change, and sample syntax lint/pyright only when files under samples/ change. They intentionally do not run workspace pyright or mypy by default.

Ruff Configuration

• Line length: 120
• Target: Python 3.10+
• Auto-fix enabled
• Rules: ASYNC, B, CPY, D, E, ERA, F, FIX, I, INP, ISC, Q, RET, RSE, RUF, SIM, T20, TD, W, T100, S
• Scripts directory is excluded from checks

Pyright Configuration

• Strict mode enabled
• Excludes: tests, .venv, packages/devui/frontend

Parallel Execution

The task runner (scripts/task_runner.py) executes the cross-product of (package × task) in parallel using ThreadPoolExecutor. Single items run in-process with streaming output.

CI Workflow

CI splits into 4 parallel jobs:

1. Pre-commit hooks — lightweight hooks (SKIP=poe-check)
2. Package checks — syntax/pyright via check-packages
3. Samples & markdown — check -S plus markdown-code-lint
4. Mypy — change-detected mypy checks
