TDQS

A4.3/5.0
Behavior4/5

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

Annotations already convey readOnlyHint=true and non-destructive behavior. The description adds meaningful context beyond that by specifying the returned fields and the fact that it is a retrieval of already-booked rental details, which helps set expectations about scope and output. It does not mention edge cases or error behavior, but the annotation coverage keeps the bar lower.

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

Conciseness5/5

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

The description is compact and front-loaded: the first sentence states the action and output, the second sentence gives concrete usage guidance. No filler or redundant restating of the tool name or schema.

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

Completeness5/5

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

This is a low-complexity read-only tool with one parameter, a fully documented schema, and an output schema present. The description covers purpose, output fields, and when to use it, so nothing critical is missing for an agent to select and invoke it correctly.

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

Parameters3/5

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

The single parameter booking_id is already fully documented in the input schema, including what it is and what it is not (a vendor confirmation number), with 100% schema description coverage. The tool description does not add additional parameter semantics, so the baseline score of 3 is appropriate.

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

Purpose5/5

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

The description uses a specific verb ('Get details') with a clear resource ('a specific vehicle booking by its Gondola booking ID') and enumerates the returned information (vendor, pickup/dropoff locations and times, vehicle class, rate, status). This clearly distinguishes it from generic get_booking and vehicle-specific siblings like get_vehicle_booking_link and get_vehicle_booking_coverage.

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

Usage Guidelines4/5

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

The description explicitly says when to use the tool ('Use when a user asks about a rental they've already booked') and gives concrete example user queries. It does not explicitly state when not to use it or name exclusion conditions versus sibling tools, so it falls just short of a 5.

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