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. However, it only states the basic action without any details on traits such as data freshness, rate limits, authentication needs, or what the output contains. This leaves critical behavioral aspects unspecified for an agent.

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 a single, efficient sentence with no wasted words. It's appropriately sized and front-loaded, directly stating the tool's purpose without unnecessary elaboration, making it easy to parse quickly.

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 tool has 2 parameters with 0% schema coverage, no annotations, and an output schema exists, the description is incomplete. It doesn't add enough context to compensate for the missing parameter semantics or behavioral traits, leaving gaps in understanding how to use the tool effectively despite the output schema handling return values.

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?

The schema description coverage is 0%, meaning parameters are undocumented in the schema. The description mentions 'specific airline' and implies 'number_of_flights' but doesn't explain what these parameters mean, their expected formats, or constraints. It adds minimal value beyond the parameter names, failing to compensate for the lack of schema documentation.

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 states the tool's purpose as 'get flights with a specific airline', which is clear but vague. It specifies the verb 'get' and resource 'flights', but lacks detail on what 'get' entails (e.g., retrieve, list, search) and doesn't distinguish it from sibling tools like 'flight_arrival_departure_schedule' or 'future_flights_arrival_departure_schedule', which may overlap in functionality.

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 doesn't mention any context, prerequisites, or exclusions, and with sibling tools like 'flight_arrival_departure_schedule' that might handle similar data, there's no indication of how this tool differs or when it's preferred.

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