ruff.toml

# Ruff is the standardization gate for this repo's Python (see CONTRIBUTING.md
# § Code conventions). Config lives here rather than in pyproject.toml because
# this repo is a skill, not a distributable package — matching pyrightconfig.json,
# which is standalone for the same reason.

# ubuntu-latest ships 3.10+; CI relies on the system python3 with no setup-python.

[lint]
# Mainstream, low-churn selection: pycodestyle, pyflakes, import order, bugbear,
# pyupgrade, simplify, comprehensions, ruff's own checks. Deliberately excludes
# the opinionated families (ANN, TRY, EM, ARG) — they would force a dialect on a
# 380-line surface without catching anything the gate below does not already.
