LLMs.txt Checker Skill
Audits any domain's AI-readiness by using curl to directly probe robots.txt, llms.txt, and llms-full.txt, then scores each file against a structured checklist and delivers a formatted report with pass/warn/fail findings and actionable fixes.
The user provides only a domain (e.g. anthropic.com or docs.example.com). Claude uses bash_tool with curl commands to directly probe the domain — no guessing, no page-scraping required.
How it works
Instead of relying on web_fetch and hoping links surface organically, this skill uses curl via bash_tool to directly request the well-known paths for robots.txt, llms.txt, and llms-full.txt. This is reliable, fast, and works regardless of how the site is built.
The curl commands follow HTTP redirects, capture response codes, and save content to temp files for auditing.
