  4. First observed

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description aligns with that by saying 'Get detailed information.' It adds behavioral context beyond annotations by specifying what categories of details are returned. Since an output schema exists, the description does not need to enumerate return fields.

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 two sentences with no filler. The first sentence states the core function directly, and the second provides workflow context and the content categories the agent can expect. Every word earns its place.

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?

For a read-only detail tool with a full output schema, complete parameter documentation, and annotations covering safety, the description covers purpose, relationship to search_Vehicles, and the types of information returned. Nothing critical for selecting and invoking the tool is missing.

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?

Schema description coverage is 100%, so each parameter already has a clear definition such as 'Rate code from search results.' The description reinforces the workflow context by saying to use it after search_vehicles, but it does not add parameter-specific meaning beyond the schema. Baseline 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') and a concrete resource ('detailed information about a specific rental vehicle option'). It also names the exact content areas (extras, insurance options, charges, cancellation policy) and positions the tool as the follow-up to search_vehicles, which distinguishes it from search and booking-focused siblings.

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 gives a clear trigger condition: 'Use this after search_vehicles to get extras, insurance options, charges, and cancellation policy for the vehicle the user wants to book.' It does not explicitly state when not to use it or name alternatives like get_vehicle_booking, but the workflow context is clear enough for an agent to route correctly.

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