passTools registered
4 / 4
1 tool registered across 1 page.
passReal-browser eligible
8 / 8
1 declarative form tool need no JavaScript API at all, so a real browser can use them as they are.
not applicableRegistration timing
0 / 4
No tool carried a measurable registration time, so how quickly this page's registry settles cannot be scored.
not applicableCanonical entry point
0 / 4
No tool is registered through the JavaScript API, so there is no entry point to score.
not applicableSchema validity
0 / 5
Declarative form tools carry their inputs as form fields rather than a JSON Schema, so there is no schema to validate.
passSchema quality
4 / 4
All 1 tool schema describe their parameters and stay within Chrome's size guidance.
not applicableStub detection
0 / 5
Every tool on this page is a declarative form, which the browser submits itself, so there is no execute handler to check.
not applicableAnnotations present
0 / 4
Declarative form tools have nowhere to declare behaviour hints, so there are no annotations to score.
not applicableAnnotation mismatch
0 / 3
No tool declares a readOnlyHint, so there is no safety claim to contradict.
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.
not applicableToolchange coherence
0 / 2
Declarative form tools live in the markup and never announce a registry change, so there is no toolchange behaviour to score.
not applicableInjection surface
0 / 3
The injection-surface model hop returned no usable result, so tool contracts were not reviewed for injection surface.
