Actually ran it against a throwaway plugins/ repo with 5 planted defects and it caught all 5 (missing marketplace 'source' field, a broken README link, a frontmatter description missing the 'Use when...' convention, a too-short marketplace blurb, a missing CHANGELOG) — but one of its 6 advertised checks (skill-validator) silently degrades to a warning because that validator lives in a separate sibling skill folder not included in a standalone install.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 9/10
- Docs & honesty 4/5
What Plugin Release Checker does
Runs a bundled Python script across a plugins/ marketplace repo to check plugin.json/marketplace.json consistency, broken markdown cross-references, frontmatter quality, and file naming, before a release. Triggers on 'release check', 'pre-release', or before running release.sh. Requires the repo to follow the same plugins/+marketplace.json layout this tool's own source repo uses, and one advertised check silently no-ops unless a separate sibling skill (skill-validator) is also installed.
How to install Plugin Release Checker

Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
