1.3 / 4

2 of 3 tool schemas are harder for an agent to use than they need to be: search_tools declares no required list, so an agent cannot tell which parameters are mandatory.

search_tools: declares no required list, so an agent cannot tell which parameters are mandatory; get_tool_review: 1 parameter has no description (slug)

fix

{
  name: "search_tools",
  inputSchema: {
    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }
    },
    required: ["query"]
  }
}

warningHuman parity

0 / 8

3 of 3 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.

search_tools, get_tool_review, list_categories

fix

<!-- Give the tool a visible counterpart: a declarative form is one the person can see and use too. -->
<form toolname="search_tools" tooldescription="...">
  <!-- the same action, as UI -->
</form>

Findings

WebMCP use

74 / 100 · weight 50

passTools registered

4 / 4

3 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 289.29999999701977ms of navigation.

toolget_tool_review

passCanonical entry point

4 / 4

All 3 tools register on the canonical document.modelContext entry point.

passSchema validity

5 / 5

All 3 tools declare a structurally valid object input schema.

warningSchema quality

toolsearch_tools

search_tools: declares no required list, so an agent cannot tell which parameters are mandatory; get_tool_review: 1 parameter has no description (slug)

fix

{
  name: "search_tools",
  inputSchema: {
    type: "object",
    properties: {
      query: { type: "string", description: "What to search for" }
    },
    required: ["query"]
  }
}

passStub detection

5 / 5

All 3 tools declare an execute handler.

passAnnotations present

4 / 4

All 3 tools declare a readOnlyHint, so an agent knows which calls change state.

passAnnotation mismatch

3 / 3

No tool claims to be read-only while its name says it writes (3 declared hints checked).

not applicableUntrusted content hint

0 / 2

No tool's contract suggests it returns text written by somebody other than the site, so there is nothing to flag as untrusted.

passRegistration errors

2 / 2

No tool registration threw during the capture.

warningToolchange coherence

1 / 2

3 tools were registered but the page never dispatched a toolchange event, so an agent subscribed to registry updates never learns they exist.

fix

// The browser fires toolchange itself on register/unregister - never dispatch it by hand.
// Retire stale tools via the registration AbortSignal so agents see a coherent registry.
var controller = new AbortController();
document.modelContext.registerTool(tool, { signal: controller.signal });
// later, when the tool no longer applies:
controller.abort();

not applicableInjection surface

0 / 3

No tool contract showed an obvious prompt-injection or unsafe-argument surface. This check only ever flags; it never credits a site.

Usefulness

100 / 100 · weight 30

passNaming quality

2 / 2

All 3 tool names are consistent, verb-led, and within Chrome's size guidance.

passDescription quality

6 / 6

All 3 rated tool descriptions say what the tool does, when to use it, and what it returns.

passTool selection

14 / 14

An agent picked the right tool and built a valid call for all 3 canonical intents.

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.

passPage experience

12 / 12

The page a person sees holds up next to the agent surface: a working interface, visible actions, readable content, nothing in the way.
