Search Airports

flighty_search_airports
Read-onlyIdempotent

Search airports by IATA, ICAO, name, or city. Returns ID, name, code, location, timezone, and website.

Instructions

Search the Flighty airport database by IATA code, ICAO code, airport name, or city name. Sorted by relevance (major airports first).

Returns: id, name, iata, icao, city, country, countryCode, timeZoneIdentifier, latitude, longitude, website.

Behavior4/5

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

Annotations indicate read-only, non-destructive, idempotent behavior. The description adds that results are sorted by relevance (major airports first) and lists return fields, providing context beyond annotations.

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?

Two brief sentences in the first paragraph cover purpose and behavior; a second paragraph lists return fields. No redundant information; every sentence earns its place.

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?

For a simple search tool with no output schema, the description provides all necessary context: search parameters, sorting, and return fields. No gaps given the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers both parameters with detailed descriptions. The description adds meaning by mentioning sorting by relevance, which is not in schema. With 100% schema coverage, baseline is 3; the added value warrants a 4.

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 searches airport data by IATA, ICAO, name, or city, and distinguishes it from siblings like flighty_search_airlines and flighty_search_flights. It specifies sorting by relevance, which is unique to this tool.

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 implicitly guides when to use (searching airports) but does not explicitly mention when not to use or compare with alternatives. However, the sibling tools are distinct enough that usage context is clear.

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