## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability llms-txt-repair-plan-checker-0a95e21e -d '<json body>'
```

Example prompt: Check mysite.com for llms.txt compliance and give me a concrete repair plan — tell me what's wrong, what the evidence shows, and exactly what I need to fix.

## When to prefer this

Choose this endpoint when you need a passive, non-intrusive evaluation of a site's llms.txt file with actionable repair guidance. Unlike a simple decision endpoint that returns only pass/fail, this repair plan variant provides specific corrective steps, making it ideal for remediation workflows, CI/CD gates, or pre-launch checklists. Prefer this over generic robots.txt or SEO checkers when the goal is specifically AI agent discoverability and llms.txt standard compliance.

## Known failure modes

- Target URL is unreachable or returns non-2xx — evidence fetch fails and no verdict can be issued
- llms.txt file is absent entirely — verdict is fail with a repair action to create the file
- Malformed llms.txt content that cannot be parsed — observation notes parsing failure
- Target domain redirects indefinitely or returns rate-limit responses — check cannot complete
- Compare URL is invalid or inaccessible — baseline comparison is skipped

## How this service works

llms.txt available 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 result containing: the observation (what was found at the target), 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 — a concrete recommendation for fixing any identified llms.txt issues.
