anthropics/claude-plugins-community gained roughly 190 stars on 2026-08-22 and was pushed again on 2026-08-23, surfacing on GitHub Trending. The repo is a read-only mirror whose .claude-plugin/marketplace.json is synced nightly from Anthropic's internal review pipeline; every listed plugin was submitted through claude.ai, passed automated security scanning, and was approved for distribution. Builders install with `claude plugin marketplace add anthropics/claude-plugins-community` then `claude plugin install <name>@claude-community`, and the same marketplace backs Claude Cowork at claude.com/plugins.
