Write the doc a new contributor opens on day one and uses to ship their first change by lunch. The center of gravity is the golden path: the exact, copy-pasteable sequence from git clone to a trivial verified change — every command grounded in the repo's real scripts and tooling, not invented make targets. Around it sit a quick architecture map (where to look, not a spec), the workflow conventions that gate a PR, and the troubleshooting that currently lives only in tribal knowledge. Deeper material is linked, never duplicated, so the guide stays true as the code moves.
Onboarding Guide Writer is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/onboarding-guide-writer/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a repo has no onboarding doc, when new hires keep asking the same setup questions, or when the README is a marketing page instead of a contributor guide.
The Onboarding Guide Writer Claude Code skill is built for content creators, marketers, copywriters, SEO professionals, and editorial teams. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 178,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
