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

With no annotations, the description carries the disclosure burden. It usefully discloses that an API key and explicit consent are required, which is relevant behavioral context for a submission tool. But it does not explain side effects, irreversibility, failure behavior, or what happens after the request is submitted, so the transparency is only partial.

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

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

The description is a single dense sentence that front-loads the action and target, then adds the two critical prerequisites. There is no filler and every word contributes.

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

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

For a tool with nine parameters, zero schema descriptions, no annotations, and no output schema, this description is not complete enough for reliable invocation. It does not specify parameter formats, allowed service types, consentText semantics, preferredTime syntax, or response/confirmation behavior; it only establishes the basic purpose and key prerequisites.

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

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

Schema description coverage is 0%, and the description adds no meaning for any of the nine parameters. It only implies consent is required, leaving fields like serviceType, cityZip, consentText, and preferredTime entirely unexplained. The description does not compensate for the lack of schema-level documentation.

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

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

The description clearly states the action (submit a booking/appointment request), the target (Covington Heat & Air), and the appointment framing distinguishes it from the sibling lead-request tool. However, it does not explicitly call out the sibling or say 'use this for bookings, not leads,' so it stops just short of full differentiation.

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

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

The description gives prerequisites ('requires an API key and explicit user consent') but no guidance on when to use this tool versus submit_covington_lead_request or the other HVAC tools. There are no when-to-use, when-not-to-use, or alternative-selection instructions.

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