Input Schema

NameRequiredDescriptionDefault
idYesAirport code (ICAO/IATA/LID)
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds the specific fields returned, which is useful but does not discuss behavioral traits like data freshness or authorization needs. No contradiction.

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?

One sentence, concise, lists the return fields. No wasted words. Front-loaded purpose.

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?

Given a simple parameter and no output schema, the description fully explains what the tool returns in a structured format. Annotations cover safety. Complete for an agent to use correctly.

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%, with the parameter 'id' described as 'Airport code (ICAO/IATA/LID)'. The description does not add extra meaning beyond the schema, so the baseline of 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 verb 'Get', the resource 'flight counts at an airport', and lists the specific fields returned: departed, enroute, scheduled_arrivals, scheduled_departures. This distinguishes it from siblings like fa_get_airport_flights (detailed flights) or fa_get_airport (airport info).

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 implies usage for aggregate counts vs. detailed flight data, but does not explicitly state when to use this tool over alternatives or when not to. It's clear enough for an agent to infer.

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