Claude Skills
The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 79 600 files from 1 763 authors, of which 61 947 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
Developer onboarding guide that composes architecture mapping, tooling review, and agentic setup review with setup, troubleshooting, and next-steps agents to produce a comprehensive guide at .turbo/onboarding.md and .turbo/onboarding.html. Use when the user asks to \"onboard me\", \"onboard to this project\", \"generate onboarding guide\", \"new developer guide\", \"how do I get started\", or \"help me ramp up\".
Capture an out-of-scope improvement opportunity so it doesn't get lost. Use when the user asks to \"note improvement\", \"save improvement\", \"track this for later\", \"remember this improvement\", \"note this idea\", \"log improvement\", \"backlog this\", or \"park this idea\". Also invoke proactively when noticing something improvable during work that falls outside the current task's scope, or after deliberately shipping a simpler approach that accepts a known ceiling — briefly mention it to the user and offer to note it.
Deep architecture report that fans out parallel inspections across different aspects of the codebase (structure, tech stack, APIs, patterns, data flow, dependencies, testing) and synthesizes findings into a comprehensive document at .turbo/codebase-map.md and .turbo/codebase-map.html. Use when the user asks to \"map the codebase\", \"map codebase\", \"architecture report\", \"codebase overview\", \"architecture overview\", \"what am I looking at\", or \"explain this codebase\".

Choose an implementation path (direct or plan) for evaluated findings and dispatch it. Direct path applies fixes directly; plan path runs /turboplan. Use after /evaluate-findings has tagged findings and they need to be implemented, or when the user asks to \"resolve findings\", \"apply evaluated findings\", or \"dispatch findings to implementation\".
