Example prompt: Can you check https://example.com for language signal issues and give me a passive repair plan — I want to know what's wrong, what the threshold is, what evidence was found, and exactly what I need to fix?

## When to prefer this

Choose this endpoint when you need a specific, actionable repair plan for language signal deficiencies on a public URL, particularly in the context of improving AI agent readability. It is distinct from generic SEO audits because it targets agent-readable language signals specifically, returns a structured verdict with evidence, and is designed for passive, non-intrusive inspection. Prefer it over sibling endpoints when the user's concern is language clarity, phrasing, or linguistic structure rather than crawlability, titles, or semantic markup.

## Known failure modes

- Target URL is unreachable or returns non-200 status — observation may be incomplete
- Target blocks crawlers or has restrictive robots.txt — evidence collection may be limited
- Malformed or non-HTTP URL input — request rejected with validation error
- No language signal issues detected — verdict passes with no repair action needed
- Rate limiting or upstream timeout — partial or empty evidence returned

## How this service works

Language signal 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 observed language signal state, the pass/fail threshold, a verdict, the exact public evidence source used, any limitations of the passive check, and a specific mode-appropriate repair action to address the identified deficiency. No login, injection, or interaction is performed.
