How this service works
Substantive llms.txt repair plan fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
Output
Returns a structured report including: the observation (what was found in the llms.txt), the threshold criteria being evaluated, a pass/fail verdict, the exact evidence source URL, known limitations of the passive check, and a mode-specific repair action the site owner can take to bring the llms.txt up to standard.
Example use cases
Pre-launch AI readiness audit
“Before we launch the new product site at acmecorp.com, can you check if our llms.txt is substantive enough for AI agents to work with — I need to know the verdict and exactly what to fix if it fails.”
Diagnosing sparse llms.txt content
“Our llms.txt at myblog.io seems too minimal — can you evaluate whether it actually meets the substantive content threshold and give me a repair plan so AI tools can properly understand the site?”
Ongoing monitoring of llms.txt quality
“Compare the current llms.txt at techstartup.com against the baseline I got last week to see whether our substantive content score has improved or if we still need repairs.”
Technical details
Endpoint
POSThttps://agentreadiness.halowerk.com/v1/llms-substantive-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to evaluate whether a site's llms.txt is substantive and actionable (not just present), and want a concrete repair recommendation. Prefer this over the 'llms.txt available' check when you already know the file exists but need to assess its quality and content depth. Ideal for site owners, SEO/AI-readiness auditors, or agents building optimization pipelines.
Side effects
- Target URL is unreachable or returns non-200 status — check fails with a network error
- llms.txt file is missing entirely — returns a specific not-found observation rather than a substantive check
- Target is behind authentication or a firewall — passive check cannot access the file
- Malformed target URL — validation error returned before any fetch is attempted
- Rate limiting or bot blocking on the target domain prevents fetching
