A3.8/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It indicates a read-only search operation and states what it returns (prices, companies, car details), but does not mention pagination behavior, date/time handling defaults, error cases, or any other side effects. This is adequate for a simple search tool but not comprehensive.

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 a single, front-loaded sentence that conveys the purpose without any filler. Every word contributes to understanding the tool's function, making it exceptionally concise and well-structured.

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

Completeness4/5

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

The description provides a clear overview of the search operation, and the rich schema covers parameter details. However, with no output schema, the description only vaguely mentions the return format ('prices, companies, and car details'). For a search tool with 8 parameters, this is sufficient for basic selection and invocation, but additional behavioral context (e.g., pagination, defaults) could improve completeness.

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 coverage is 100%, so the input schema already documents all 8 parameters with descriptions. The description adds minimal new meaning beyond the schema—it highlights the core parameters (pickup/dropoff locations/dates) but does not elaborate on their formats or constraints, which are already in 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 clearly states the tool's purpose: 'Search Skiplagged for rental cars between pickup and dropoff locations/dates, returning prices, companies, and car details.' It specifies the verb (search), resource (rental cars), key parameters (pickup/dropoff locations/dates), and output (prices, companies, car details), which distinguishes it from sibling flight and hotel search 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 description implies usage for car rental searches but does not explicitly state when to use this tool versus alternatives or when not to use it. Sibling tool names (e.g., skiplagged_sk_flights_search) provide contextual differentiation, but the description lacks explicit usage guidelines such as prerequisites or exclusions.

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