llms-txt-check-links

name	llms-txt-check-links
description	Run link checking for URLs in llms.txt and help the user fix broken or redirected links.

Goal

Check that links referenced in llms.txt are reachable, then fix any broken ones with minimal changes.

Steps

1. Run:
   • php bin/llms-txt-cli check-links
2. If failures occur:
   • Group them:
     • 404/410: update/remove link
     • 301/302: decide whether to pin final URL
     • timeout: retry; consider network/proxy
3. Fix strategy
   • Prefer HTTPS where available.
   • Prefer stable canonical docs URLs over volatile branch URLs.
   • If a link is intentionally private/unreachable, suggest removing it or marking it appropriately (without inventing nonstandard syntax).

Ask for context when needed

• Is the repo public or private?
• Are links intranet-only?
• Are CI runners allowed outbound internet?

Example

User: “CI fails on check-links.” Assistant:

• “Paste the check-links output; I’ll propose the smallest edit(s) to llms.txt to make all URLs pass.”
