passRegistration timing
4 / 4
Every measured tool registered within 136.80000019073486ms of navigation.
failCanonical entry point
0 / 4
Every tool registers through the deprecated navigator.modelContext alias; move them to document.modelContext before the alias is removed.
fix
// Use the canonical entry point - navigator.modelContext is deprecated.
document.modelContext.provideContext({ tools: [/* ... */] });
failAnnotations present
0 / 4
1 of 1 tools declare no readOnlyHint, so an agent cannot tell a read from a write without guessing from the name.

}
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.

fix
{ name: "send_feedback", annotations: { untrustedContentHint: true } }
warningHuman parity
0 / 8
1 of 1 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
1 tool registered across 1 page.

8 / 8
A real browser exposes modelContext natively on this page, so the tools registered here are visible to an agent today.
passRegistration timing
4 / 4
Every measured tool registered within 136.80000019073486ms of navigation.

fix
// Use the canonical entry point - navigator.modelContext is deprecated.
document.modelContext.provideContext({ tools: [/* ... */] });
passSchema validity
5 / 5
All 1 tool declare a structurally valid object input schema.
passSchema quality
4 / 4
All 1 tool schema describe their parameters and stay within Chrome's size guidance.
passStub detection
5 / 5
The one registered tool declares an execute handler.
failAnnotations present

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.

send_feedback: feedback, reply, user
fix
{ name: "send_feedback", annotations: { untrustedContentHint: true } }
passRegistration errors
2 / 2
No tool registration threw during the capture.
warningToolchange coherence
1 / 2
1 tool was 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.

passNaming quality
2 / 2
All 1 tool name is 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.
