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.
