Luban — a Skill workshop. Refine a usable Skill into a public asset that can be understood, installed, shared, validated, and continuously improved. Its craft-based method has five steps: inspect the material (challenge the Skill’s premise first and say plainly when it is not worth refining), survey the field (search online for similar Skills and understand its place in the ecosystem), measure it (assess structure, real-world tests, and live runs together—the latter means checking actual outputs, since green CI can lie), plane slowly (freeze the original as a baseline; keep changes only if they pass validation, otherwise revert; wherever possible, preserve validation methods as repository tools and conventions), and rework (publication is not the finish line; keep a comparison watchlist and use real feedback in the next round). Use when users want to upgrade, optimize, refine, productize, or publish a Skill they developed. The final deliverables are a structured “Skill Refinement Report,” rewrite snippets ready to replace the originals, and a shareable “certificate of mastery” result card. Triggers include, but are not limited to: “let Luban review this skill,” “refine my skill,” “upgrade my skill,” “optimize this skill,” “skill checkup,” “skill audit,” “productize my skill,” “how do I publish this skill,” “compare it with similar skills,” “why is nobody installing my skill,” “help me publish my skill to GitHub/ClawHub,” and “improve SKILL.md.” Even if the user only shares a Skill directory, GitHub repository link, or SKILL.md and asks “how should I change this?”, trigger it whenever the context is to make the Skill more useful and shareable. Do not use it to create a new Skill from scratch (use skill-creator), for ordinary code review (use code-review), or to rewrite a general prompt unrelated to Skill assets.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
