warningHuman parity
0 / 8
9 of 9 tools run through the JavaScript API with no visible counterpart, so the person co-browsing cannot see what the agent is offered. Declarative forms (or at least a title annotation) close the gap.

passTools registered
4 / 4
9 tools registered across 1 page.
failReal-browser eligible
0 / 8
The page's code registers these tools, but a real visitor's browser does not get them yet: WebMCP needs a native modelContext or a current origin trial token, and this page has neither.
passRegistration timing
4 / 4
Every measured tool registered within 509.7000000476837ms of navigation.
toolshare_site
passCanonical entry point
4 / 4
All 9 tools register on the canonical document.modelContext entry point.
passSchema validity
5 / 5
All 9 tools declare a structurally valid object input schema.
warningSchema quality
3.1 / 4
2 of 9 tool schemas are harder for an agent to use than they need to be: get_service_catalog 1 parameter description is over Chrome's 150-character guidance.
toolget_service_catalog
get_service_catalog: 1 parameter description is over Chrome's 150-character guidance; share_site: declares no required list, so an agent cannot tell which parameters are mandatory
fix
{
  name: "get_service_catalog",
  inputSchema: {
    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }
    },
    required: ["query"]
  }
}
passStub detection
5 / 5
All 9 tools declare an execute handler.
failAnnotations present
0 / 4
9 of 9 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.
toolget_business_info
get_business_info, get_service_catalog, get_faqs, get_contact_channels, calculate_service_price
fix
{
  name: "get_business_info",
  annotations: { readOnlyHint: true, destructiveHint: false, idempotentHint: true }
}
not applicableAnnotation mismatch
0 / 3
No tool declares a readOnlyHint, so there is no safety claim to contradict.
warningUntrusted content hint
0 / 2
1 of 1 tools look like they return text written by other people but declare no untrustedContentHint, so an agent will treat the response as the site speaking.
toolget_contact_channels
get_contact_channels: message, email
fix
{ name: "get_contact_channels", annotations: { untrustedContentHint: true } }
passRegistration errors
2 / 2
No tool registration threw during the capture.
warningToolchange coherence
1 / 2
9 tools were registered but the page never dispatched a toolchange event, so an agent subscribed to registry updates never learns they exist.
fix
document.modelContext.dispatchEvent(new Event("toolchange"));
not applicableInjection surface
0 / 3
The injection-surface model hop returned no usable result, so tool contracts were not reviewed for injection surface.

Usefulness

100 / 100 · weight 30
passNaming quality
2 / 2
All 9 tool names are consistent, verb-led, and within Chrome's size guidance.
not applicableDescription quality
0 / 6
The description-quality model hop returned no usable result, so descriptions were not rated.
not applicableTool selection
0 / 14
The tool-selection model hop returned no usable result.
not applicableCoverage vs. site type
0 / 8
This tool set does not place the site in a category with a known expected tool shape, so there is no coverage baseline to score it against.
