Example prompt: Can you check https://myservice.com for agent card discoverability issues and give me a concrete repair plan showing exactly what needs to be fixed and why?

## When to prefer this

Choose this endpoint when you need not just a pass/fail verdict on agent card discoverability but also a concrete, actionable repair plan telling you exactly what to fix. Prefer it over audit-only or decision endpoints when the goal is remediation rather than monitoring. It is ideal for developers preparing a new service for AI agent discovery, diagnosing a regression, or producing a structured fix checklist.

## Known failure modes

- Target URL is unreachable or returns non-200 status — evaluation may be incomplete or return limited evidence
- Private or authenticated endpoints cannot be inspected since no login is attempted
- Rate-limited targets may return incomplete data, affecting verdict accuracy
- Malformed or non-HTTP URLs result in normalization errors or rejection
- Agent card standard evolves faster than check criteria, causing stale thresholds

## How this service works

Agent card discovery 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 evaluation containing the observed evidence found at the target URL, the threshold criteria being evaluated, a pass/fail verdict, the exact evidence source (URL or location), any limitations of the passive check, and a mode-specific action plan describing exactly what to change to fix the agent card discoverability issue.
