Modern Python Project Instructions (uv + ruff + pytest)

CLAUDE.md for Python projects managed with uv: dependency rules, ruff lint/format gates, pytest conventions, and a no-untyped-code policy agents can verify.

Use when: Use in any Python 3.12+ project that uses uv for environments and packaging, so agents run the right commands and never reach for pip, poetry, or unformatted code.
