How It Works

Multi-Platform Discovery

Skills are discovered across Claude Code, Cursor, Codex, Windsurf, and Cline by scanning for platform-specific markers like SKILL.md, .cursorrules, AGENTS.md, and more.

Quality Scoring

Each skill is scored on 12 structural quality signals: gotchas/edge cases, progressive disclosure, verification layers, code examples, and more. Quality is 60% of the ranking — not stars.

AI Categorization

Skills are classified into 9 use-case types derived from production lessons scaling to 500+ skills at Uber. Each type maps to a real workflow.
