ClawHub is a full-stack registry marketplace for AI agent skills and OpenClaw plugins. It provides a web application (React + TanStack Router + Convex backend), a CLI tool (clawhub) for publishing and managing skills, an admin CLI for moderation, and a public HTTP API. The system handles skill/plugin publishing, versioning, search (with OpenAI embeddings), trending leaderboards, security scanning (VirusTotal, ClawScan, static analysis), moderation, and catalog feeds. It also mirrors an external skills.sh catalog. The architecture is a monorepo with shared schema packages, extensive test coverage (unit, e2e, Convex), and CI/CD via GitHub Actions. While primarily an application, it includes data/research elements like security dataset export and ranking metrics pipelines.
