warningUntrusted content hint

2 of 2 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.

warningHuman parity
4 / 8
1 of 2 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.

Findings

WebMCP use

77 / 100 · weight 50
passTools registered
4 / 4
1 imperative tool and 1 declarative form 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. The 1 declarative form tool on the page stay usable regardless.
passRegistration timing
4 / 4
Every measured tool registered within 902.1000001430511ms of navigation. 1 further tool carried no measurable registration time.
tooldiscover_symbaiex_agent_access
passCanonical entry point
4 / 4
The one registered tool registers on the canonical document.modelContext entry point.
passSchema validity
5 / 5
All 1 tool declare a structurally valid object input schema.
passSchema quality
4 / 4
All 2 tool schemas describe their parameters and stay within Chrome's size guidance.
passStub detection
5 / 5
The one registered tool declares an execute handler.
passAnnotations present
4 / 4
All 1 tool declares 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 (1 declared hint checked).
warningUntrusted content hint
0 / 2
2 of 2 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: "discover_symbaiex_agent_access", 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.

not applicableCoverage vs. site type
0 / 8
