search_italy_transport

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

No annotations are provided, so the description carries full responsibility. It states the return type (JSON with options, prices, operators) but does not disclose any side effects, rate limits, authentication needs, or pagination. For a search tool, the description is adequate but lacking in detail.

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 concise: one line for purpose, then args, then returns. No redundant information. It is front-loaded with the search purpose and structured clearly.

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?

Given the presence of an output schema (though not fully shown), the description adequately covers purpose, parameters, and return type. It mentions Italian cities but could specify transport modes (train, bus?) or add more examples. Overall, it is fairly complete.

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%, but the description compensates by listing all three parameters with explanations and examples (e.g., 'from_city: Origin city slug (e.g. ''rome'', ''milan'', ...)'). The date parameter is described as optional with format YYYY-MM-DD. This adds meaning beyond the schema's bare titles and default.

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 tool's purpose: 'Search for transport options between two Italian cities.' It specifies the verb 'search' and the resource 'transport options'. It distinguishes itself from siblings like list_italy_routes and get_cheapest_travel_day by focusing on searching rather than listing or cheapest day.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, when not to use, or how it relates to siblings like get_cheapest_travel_day. The user must infer usage from the name and description alone.

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