A4.2/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/openWorld/non-destructive, so the bar is lower, yet the description adds real operational context: a $0.25 per-call charge, per-region data coverage limits (US-only FAA programs, Norway-only boards), and graceful degradation signaled by sections_failed[]/notes[]/coverage[]. It does not state rate limits or auth requirements, which keeps it out of the top band.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is correctly front-loaded, but the long 'Returns:{...}' field dump duplicates what the output schema already provides and makes the block a dense run-on. The information is mostly useful but the packaging is heavier than it needs to be.

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?

Given 6 params, an output schema, and rich annotations, the description covers the remaining agent-facing unknowns: cost, regional coverage, partial-failure signaling, and input modes. It leaves unresolved what happens if both airport and callsign are supplied (or neither, beyond minProperties), which is the only notable gap.

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 coverage is 100%, so 3 is the baseline; the description earns above baseline by grouping airport and callsign as mutually alternative entry points, which the schema's minProperties:1 does not express. It does omit the language parameter entirely from its Input list, leaving that one purely to the schema.

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?

Specific verb+resource pairs throughout: live flight status, airport delays, FAA ground stops, departure/arrival boards, METAR/TAF weather, and aircraft position by callsign. It even scopes each capability by region (FAA/US, boards/Norway, weather/any ICAO), so an agent knows exactly what class of data comes back without opening the schema.

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 'Input: airport (IATA or ICAO) or callsign' clause resolves the critical ambiguity created by required=[] and minProperties=1 — the agent learns this tool is invoked either by airport code or by callsign, and that flight/direction/hours_ahead are modifiers. It stops short of stating when-not to use it or pointing at a sibling (e.g., hubvibe_maps_weather for general weather).

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