B3.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructive=true, non-idempotent, non-readonly, so the safety profile is partly covered. The description adds substantial non-obvious behavior: the call is asynchronous, costs $0.50 per call, has no free preview, and an unpaid MCP call returns payment instructions. It stops short of explaining what the destructive 'cancel' action actually alters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The opening sentence and the payment disclosure are efficient and front-loaded, but the 'Selection' clause duplicates the 'When' clause word-for-word, wasting roughly a third of the text on a templating artifact rather than new information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The presence of an output schema means return values need not be described, and the payment/async behavior is covered. Still, for a 9-parameter tool with nested objects, zero schema descriptions and five required inputs, the description leaves an agent without enough guidance to populate the request correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 9 parameters including nested 'safety' (recording, consentNotice, transcription) and 'context' objects, and the description explicitly defers everything with 'see the schema'. Only the action enum is echoed, leaving phoneNumber, timezone, language, appointmentType, availableSlots, and maxDurationSeconds unexplained in both places.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource — 'Place an asynchronous appointment call' — and enumerates the scheduling actions (propose, book, confirm, reschedule, cancel), which maps precisely to the schema enum. It is clear what the tool does, though it never names the nearest sibling (ai_call_agent, voice_lead_qualifier) to distinguish itself from other telephone-agent tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'When' clause gives a usable trigger condition (an authorized agent coordinating a customer appointment by telephone and needing a machine-readable scheduling result). However, the 'Selection' clause degenerates into a verbatim repetition of the 'When' sentence, so no genuine alternatives or when-not conditions are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
