F18 · Base checks
Agent, API & service discovery
OpenAPI / ai-plugin / MCP-style surfaces (site-type aware)
Why it is checked
Checks whether your site publishes machine-readable API/agent surfaces (OpenAPI spec, plugin manifests) so AI agents can understand what your service offers.
How it counts
Optional. Passing can add up to 2 bonus points; all optional items together are capped at 10. Not having it never lowers your base score.
How results read
The wording below is exactly what a report shows for each result.
- Passed
In this check, your site looks good on this point — no action needed.
- Declared · incomplete
In this check, we found something that weakens this signal. It is not fatal, but fixing it makes your site easier for AI answer engines to use — see the suggested steps below.
- Not found · optional
Your site looks like an API or documentation product, but no OpenAPI spec or agent manifest was found. Publishing one makes it more likely that AI agents can understand and call your service. Optional capability — whether to add it depends on your site's purpose; it does not affect your base score.
- Couldn't verify
We could not determine this item in this check — the available evidence is not enough to tell why. No conclusion is drawn either way.
How to fix it
Fix steps depend on what the check actually finds on your site, so they appear in your report next to this item, together with the evidence. Rule templates only — no AI model writes them.
