description	Run precommit.sh before committing — invoke after any code or documentation edit, and before staging. It modifies files in place, so re-check the diff afterward. Applies isort, black, ruff, mypy, codespell, and markdownlint in sequence, stopping at the first failure

./bin/precommit.sh

Runs in order: isort → black → ruff → mypy → codespell → markdownlint. It modifies files — isort, black, ruff, and markdownlint all apply fixes in place (codespell only reports; fix manually or run uv run codespell -w and review the diff — its auto-fix can rewrite intentional forms). After a successful run, check for modified files and include them in the commit.

It does not run tests. Use the tests-run skill for that.

The script stops at the first failure (set -euo pipefail), so a failure in ruff means mypy, codespell, and markdownlint have not yet run. isort, black, and markdownlint are unlikely to fail since they auto-fix. Ruff may report unfixable lint errors; mypy reports type errors; codespell reports misspellings and British spellings — all require manual fixes before re-running. The spelling rule and its inline-ignore convention are owned by ref-python-coding-practices rule 8 (markdown delta: ref-markdown-documentation-standards Prose conventions).

Ruff/mypy failures need code edits — apply the review-python-file skill (which loads ref-python-coding-practices, ref-logging-standards, and ref-mcp-module-organization) before fixing, so the fix matches project standards rather than only silencing the linter.
