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

Adds substantial context beyond the annotations: nothing is paid online, no booking fee, the examiner contacts the person and agrees date/payment/cancellation terms, and payment goes directly to the examiner. It also discloses the return payload (booking reference, office, page link) and a security constraint about not putting contact details in a URL — none of which the annotations convey.

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?

Front-loads the core action, then cost, then the usage restriction, then the return value. Every sentence carries information, though it is on the denser side for a single tool call.

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?

No output schema exists, yet the description explains what comes back (booking reference, office, page link) and what the person can do with it. Combined with the payment and consent framing, an agent has everything needed to invoke this correctly.

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 100%, so all seven parameters are already documented in the schema. The description only lightly reinforces 'location' and contact details via the URL warning; it adds no new field-level semantics. Baseline 3 is appropriate.

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?

States a specific verb and resource: sends a free appointment request directly to the examiner covering the chosen location. It's immediately distinguishable from its read-only siblings (find_offices, get_pricing, get_booking_status, get_service_info) because it is clearly the one that creates a request.

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?

Explicitly constrains use: 'Only use this when the person has asked you to send the request with these details.' That is a clear precondition. It does not name which sibling to use instead when the person is just browsing, so it falls short of the top band.

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