fa_get_airport_weather

Read-only

Retrieve current METAR observations or TAF forecasts for an airport using its ICAO, IATA, or LID code to support flight planning and weather checks.

Instructions

Get weather for an airport: current METAR observations, or the TAF forecast.

Input Schema

NameRequiredDescriptionDefault
idYesAirport code (ICAO/IATA/LID)
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns FlightAware's payload untouched. No field projection: this server has no verified record of which FlightAware fields matter, and inventing one would risk dropping a field a caller needs.
cursorNoPaging cursor: the cursor query parameter of a previous response's links.next (passing the whole links.next value also works)
reportNoobservations (METAR) or forecast (TAF)observations
max_pagesNoMax pages to fetch, 1-20 (AeroAPI default: 1). Capped at 20 since AeroAPI bills per page.

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that output is METAR/TAF data, but says nothing about auth, rate limits, or billing behavior (billing is only hinted at in the schema's max_pages note). Adequate but thin.

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?

A single front-loaded sentence with zero waste. The resource and the two report variants come first, which is exactly what an agent needs to route on.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only lookup with full schema coverage and no output schema, the description is sufficient to call correctly. It could optionally note the default view/report behavior or pagination expectations, but nothing essential is missing.

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 description coverage is 100%, so the schema already documents all five parameters in detail (id pattern, view semantics, cursor, report enum, max_pages billing cap). The description only restates the report concept, adding no meaning beyond the schema. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource (get weather for an airport) and enumerates the two content types returned (METAR observations, TAF forecast). No sibling tool covers weather, so differentiation is inherently satisfied, but the description does not call this out explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'current METAR observations, or the TAF forecast' implies which option to pick via the report parameter, but there is no explicit when-to-use guidance, no prerequisites, and no mention of alternatives. Usage is only implied.

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