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

No annotations provided; description implies read-only query but does not explicitly state side effects or safety. Return behavior is hinted ('returns ranked destinations by price') but not detailed.

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?

Concise, well-structured description with bold heading, example, and bullet-point-like parameter list. No unnecessary words.

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?

Adequately covers parameter semantics and usage context for a simple search tool. Lacks output format details but complexity is low; no output schema to rely on.

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?

With 0% schema coverage, description compensates by explaining each parameter (e.g., origin as IATA code, month format, regions examples). Adds meaning but could clarify allowed values for currency and month format.

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?

Description clearly states 'Find cheapest destinations from origin airport' with example query. Distinguishes itself from siblings like 'find_cheapest_month' by focusing on any destination ranked by price.

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?

Provides explicit example and mentions round_trip_days for realistic budgeting. Gives context on when to use (finding cheap flights) but does not contrast with alternatives like 'find_destinations_by_budget'.

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