Anthropic's knowledge-work-plugins at 31,595 Stars: 123 Marketplace Entries, 11 in the README, and Only 2 of 17 Plugins Ship a Slash Command

The README of anthropics/knowledge-work-plugins opens with a promise and then makes four claims you can check against the files: “We’re open-sourcing 11 plugins”, “Each plugin bundles the skills, connectors, slash commands, and sub-agents for a specific job function”, “Every component is file-based — markdown and JSON, no code, no infrastructure, no build steps”, and “Plugins are just markdown files. Fork the repo, make your changes, and submit a PR.”

Every one of those sentences is contradicted by something inside the repository, and the contradictions are not subtle. The marketplace registry has 123 entries. There are 17 first-party plugins on disk, not 11. The repo ships 26 Python files, and GitHub’s own language bar for the repository reads Python 74.1%, HTML 25.9% — there is no markdown percentage, because GitHub does not count it. Slash commands exist in 5 files across 2 of 17 plugins. And the pull-request workflow closes external contributions automatically with a comment explaining that this repository only accepts contributions from Anthropic team members.
