For Agents Updating Skills

When modifying skills in this repository:

  1. Each skill is a directory under plugins/cpython-skills/skills/ containing a SKILL.md file
  2. SKILL.md format: YAML frontmatter (name, description) followed by markdown instructions
  3. Keep skills focused: Each skill should cover a specific domain (build, test, style, docs)
  4. Descriptions are critical: The description is the primary triggering mechanism - include specific contexts and triggers
  5. No extraneous files: Don't add README.md or other auxiliary files in skill directories
  6. Avoid duplication: Information should live in one skill only, not repeated across skills
  7. Keep SKILL.md concise: Under 500 lines; split to reference files if needed
  8. Update top-level README.md if adding new skills or changing skill purposes
