AI agents now read and write docs alongside your team. They do that work better when they have clear instructions for it. So we’ve put free documentation skills, a Skill generator and Agent score together on one page: the Docs AI Toolkit, at gitbook.com/ai-toolkit.
Everything in it is free. It works with any docs site, wherever it’s hosted, and you don’t need a GitBook account.
The toolkit was shaped by what we heard at our hands-on Write the Docs workshop in San Francisco. Read the event recap.
A skill is a SKILL.md file: packaged instructions an agent loads when it’s relevant. You can add these to Claude, Cursor, Codex, Gemini CLI and other agents that support SKILL.md files.
AI readability check: checks and fixes docs pages so AI assistants and retrieval systems can chunk, retrieve, and quote them.
Humanizer: reviews or rewrites AI-sounding docs, release notes, and READMEs so they read like a skilled technical writer wrote them.
Prerequisite gap checker: finds the steps, permissions, and setup a task page assumes but never states.
Release notes writer: drafts user-facing release notes and changelogs from PRs, commits, tickets, and diffs.
SEO and AEO documentation: creates, edits, or reviews docs for content-level SEO and AEO without sacrificing readability or accuracy.
The Skill generator takes your docs URL and returns a SKILL.md that works with Claude, Cursor, Codex, Gemini CLI and 30+ other agents. Your agents get your product knowledge in a format they can use right away.
Agent score checks how easily AI agents can reach, parse, and use your docs. It’s built on Dachary Carey’s open-source afdocs library, plus a few checks of our own.
Each skill installs with a single command. For example, to add the AI readability check:
Install a skill with a command like the one above.
Run it on one page. Start with a page you know well, so you can judge the suggestions.
Generate a skill from your docs so your agent knows your product before it starts writing.
Check your Agent score to see how agents experience your site today.
The source for every skill is on GitHub at GitbookIO/docs-skills. Have an idea for a skill your team needs? Open an issue there and tell us.
