What it does

  • Runs the bundled review_skill.py reviewer to check frontmatter quality, directory structure, SKILL.md size, hardcoded paths and secrets, script hygiene, and subagent_type validity.
  • Uses clear exit codes (0 clean, 1 warnings, 2 review errors, 3 runtime failure) so results are easy to automate.
  • Offers three modes: self-review before publishing, external review of someone else's repo, and auto-PR (fork → improve → submit).
  • Enforces an "additive only" contribution principle plus PR tone guidance and required PR sections.

Who it's for

  • Authors publishing Claude Code skills or marketplace plugins
  • Team leads standardizing skill quality across a repo
  • Open-source contributors sending improvement PRs to skill repos

Examples

  1. "Review my pdf-extractor skill before I publish it" → flags a non-third-person description and missing trigger conditions.
  2. "Evaluate this GitHub skills repo" → clones to /tmp, reads all docs, runs the checklist, produces an improvement report.
  3. "Open a PR improving this skill's description" → forks with gh, branches, applies additive edits, passes the respect checklist, drafts the PR.
