Python profile

What this profile covers

Idiomatic Python source code: type hints and typing usage, mutability and aliasing, context managers, exception hygiene, packaging boundaries, async idioms, testing/mocking pitfalls, and SOLID principles adapted to Python's duck-typed model.

When it activates

Any file with a .py or .pyi extension in scope. See DETECTION.md for the authoritative rule. Activation is additive with other profiles on the same diff.

Populated phases

• review-code/ — checklists consumed by review-code (security, SOLID, code-quality, removal-plan).

Other phase subdirectories are not populated for this profile: generic per-phase behavior is sufficient.

Looking up Python dependencies

When adding or upgrading a dependency, follow the dependency-handling skill's cascade:

1. capy-first — query the project's indexed kk:lang-idioms / kk:project-conventions / prior context7 fetches.
2. context7 — fetch current docs for the package; most mainstream PyPI packages are indexed there.
3. web — fall back to pypi.org, the project's own repository README, or readthedocs.io mirrors only if the first two yield nothing.

Project dependency metadata lives in pyproject.toml, requirements.txt, or poetry.lock / pdm.lock. Version-specific behaviors must be verified against the version the project resolves to, not the latest available.
