What problem does it solve? When maintaining a plugin marketplace repository, it is easy to forget to bump a plugin's version after changing its files, or to let marketplace.json drift out of sync with the actual plugin directories. This Skill audits the current branch against its merge base and reports every version and registration inconsistency before you merge or open a PR. ## Core Features & Use Cases - Version Bump Detection: Compares each changed plugin's plugin.json version against the merge base and flags missing, regressed, or invalid version bumps. - Marketplace Sync Validation: Verifies every plugins/ directory has a marketplace entry, every entry points to a real plugin, and version fields live only in plugin manifests. - Codex Manifest Cross-Check: Ensures .codex-plugin/plugin.json versions match their Claude counterparts when both exist. - Use Case: After merging main into your feature branch, run the check to confirm all modified plugins received appropriate semver bumps and marketplace.json is fully synchronized before creating a pull request. ## Quick Start Ask the assistant to check versions and verify that all plugin version bumps and marketplace entries are correct on the current branch.
