get_agent_summary

Returns who Aidan is and what work it performs: role, workflow, deliverables, and operating guardrails. Read-only. Use this to decide whether the agent fits a task. Does not include pricing — call get_pricing for commercial terms. Returns a JSON object with agent, site, operator, summary, deliverables[], and standing_rules[].Answers a question. Declared read only.

5 of 6 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

94 / 100 · weight 50
passTools registered
4 / 4
5 imperative tools and 1 declarative form registered across 1 page.
passReal-browser eligible
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 889.5ms of navigation. 1 further tool carried no measurable registration time.
toolget_policies
passCanonical entry point
4 / 4
All 5 tools register on the canonical document.modelContext entry point.
passSchema validity
5 / 5
All 5 tools declare a structurally valid object input schema.
passSchema quality
4 / 4
All 6 tool schemas describe their parameters and stay within Chrome's size guidance.
passStub detection
5 / 5
All 5 tools declare an execute handler.
passAnnotations present
4 / 4
All 5 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 (5 declared hints checked).
warningUntrusted content hint
0 / 2
3 of 3 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.
toolstart_subscription
start_subscription: review, user; brief_agent: review, message, post; brief_agent: review, email
fix
{ name: "start_subscription", annotations: { untrustedContentHint: true } }
passRegistration errors
2 / 2
No tool registration threw during the capture.
warningToolchange coherence
1 / 2
5 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

57 / 100 · weight 30
warningNaming quality
1.7 / 2
Tool naming makes selection harder than it needs to be: 2 names do not start with a verb (brief_agent).
toolbrief_agent
fix
{ name: "brief_agent" /* short, unique, verb-based */ }
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.
warningCoverage vs. site type
4 / 8
The tool set covers 2 of the 4 things an agent needs on a saas site; it cannot search or browse the catalog or update or move an existing record.
