Assess flight conditions, with escalation

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

No annotations are provided, so the description carries the full burden, and it does substantial work: it discloses the returned fields (category, confidence, underlying observations, requiresHumanReview) and the concrete failure modes that trigger review (boundary proximity, missing data, significant weather, disagreeing sources). It stops short of stating permission/auth needs or the fact that this is a non-mutating read.

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?

Three sentences, front-loaded with the action and outputs, then the escalation rule flagged with an explicit IMPORTANT marker. Every sentence earns its place and nothing is repeated from the schema.

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?

With no output schema the description must describe returns, and it does so thoroughly, including the escalation contract. Missing only secondary details such as source freshness, whether it is purely read-only, and any rate or auth constraints.

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?

Schema coverage is 100% and the single 'station' parameter is fully documented in the schema with a pattern and example. The description's 'at an airport' adds only light context, so the baseline 3 for high schema coverage applies.

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?

States a specific verb+resource ('Assess current flight conditions at an airport') and enumerates the outputs, which implicitly distinguishes it from the raw-data siblings get_metar and get_taf. Differentiation is implied by the assessment/interpretation framing rather than stated outright, so it falls short of a 5.

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?

Gives strong conditional guidance for the output case ('when requiresHumanReview is true, do not present the category as settled... hand off to a person'), but never says when to choose this tool over get_metar/get_taf or search_stations. Usage selection guidance is implied at best.

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