This list undergoes nightly synchronization from Anthropic's internal review system, ensuring all listed plugins have completed security scanning and received approval for distribution.\n\n## Installation Methods\n\nFor Claude Cowork users, plugins can be installed directly through the plugins interface. Claude Code users access community plugins via command line:\n\n```bash\nclaude plugin marketplace add anthropics/claude-plugins-community\nclaude plugin install <plugin-name>@claude-community\n```\n\n## Submission Process\n\nPlugin developers must submit their work through the official submission portal rather than via direct repository pull requests. The documentation notes that submissions undergo automated security review before approval.\n\n## Related Resources\n\nThe repository references two companion projects: Anthropic's official plugin collection and specialized role-specific knowledge-work plugins, providing developers with additional context about the broader plugin ecosystem."}]},"uuid":"15d35be4-2cd9-4074-817c-282e5a088c0e","timestamp":"2026-07-21T08:00:40.412Z","sourceToolAssistantUUID":"461a9e08-2b98-4c8e-9de3-f908540d2373","userType":"external","entrypoint":"sdk-ts","cwd":"/workspace/agent","sessionId":"033a4a00-9171-4e08-9a79-6b99f177355d","version":"2.1.128","gitBranch":"HEAD","slug":"mellow-wobbling-swan"}
