Codebase Onboarding

What it is

Reads a repository and writes an onboarding path: how to run it, the three files that matter first, where the entry points are, and how to make a trivial change safely. The constraint is order — every section must be something the reader can do before the next one.

Install

Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

How to judge it

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
