OpenWiki auto-generates the files that steer AI coding agents

LangChain's OpenWiki writes pull requests against CLAUDE.md and AGENTS.md on its own, per the project's GitHub page.

CLAUDE.md tells a coding agent how to behave inside a repo. OpenWiki treats it as something to generate and refresh, not something written once by hand.

The tool builds two wikis. One covers the repo, in an openwiki/ folder. The other is personal, at ~/.openwiki/wiki/, pulled from Gmail, Notion, GitHub, X, web search, and Hacker News.

Wired into CI/CD, it keeps both files current, opening new pull requests whenever the repo changes. It's an MIT-licensed TypeScript CLI. It launched June 22 and passed 11,768 stars by July 13, when it shipped v0.1.2, about 490 stars a day, per its GitHub page.

I've had hand-maintained CLAUDE.md files rot within weeks, drifting from what's actually true about the codebase. A stale instruction file is worse than none, because it actively misleads the agent. Generating it automatically solves that specific problem.

That safety case only holds if someone reads the pull requests before merging them. Merge them on autopilot and the agent ends up editing its own rulebook. Nothing outside the loop checks whether the edits track the codebase or just whatever kept the last run green.
