This validates your documentation site before pushing to GitHub Pages. It counts your agents and skills, checks that your marketplace.json and plugin.json files are valid JSON, and gives you a quick preflight checklist. The skill is part of the compound-engineering-plugin from Every, which has picked up decent traction with 19K stars. It's straightforward validation work, the kind of thing you'd otherwise run manually before each deploy. If you're maintaining a Claude plugin with agents and skills, this automates the boring but necessary checks. Nothing fancy, just saves you from breaking your docs site with malformed config files.
