This skill makes Claude refresh your repo's llms.txt, the file that tells language models where to find your docs. Claude reads the current file and the repo structure, finds new, moved or removed docs, and rewrites the file in the llmstxt.org format.

The folder has one file, SKILL.md, and no scripts. The target file is llms.txt in the repository root. SKILL.md ends with a checklist for format, content and spec compliance.

Good for

Maintainers who publish an llms.txt for their repo
Docs teams that add or move pages often
Anyone who wants link lists kept in step with the repo tree
