gpshead/cpython-skills

Use this skill when you need to compile CPython, run tests, verify your changes work, check if a fix is correct, or debug test failures. Covers building from source with ./configure and make, ccache for faster rebuilds, Argument Clinic regeneration, and the unittest-based test system (NOT pytest). Essential for any task that requires running code or tests.

This skill triggers when any cpython-skills skill is requested. The cpython-skills plugin has been renamed to cpython for simpler invocation.

Use this skill when editing documentation, working with files in Doc/, adding versionadded or versionchanged markers, creating NEWS entries for bug fixes or features, or building the HTML docs. Covers reStructuredText (.rst) format, documentation validation, and NEWS file requirements.

Use this skill when preparing commits, running pre-commit hooks, checking code style, or validating changes before pushing. Covers PEP 7 (C code) and PEP 8 (Python) compliance, trailing whitespace rules, the no-type-annotations-in-Lib policy, and patchcheck validation. Note: patchcheck requires a build directory - load the `build` skill first if you haven't built CPython yet.
