OpenSky — Live Flights by Country

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

The description adds little beyond the annotations which already indicate read-only and open-world. It mentions 'live' and 'airborne', but does not disclose data freshness, rate limits, or other behaviors. The bar is low due to annotations, but the description provides minimal added context.

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?

The description is extremely concise with one sentence stating the purpose followed by a parameter list. No unnecessary words, and the purpose is front-loaded.

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?

Given the tool has 3 parameters with no schema descriptions, no output schema, and several siblings, the description does not cover return values, pagination, or how to interpret results. Significant gaps remain despite the concise format.

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 description coverage is 0%, so the description must compensate. It lists parameters and gives an example for 'country', but does not explain 'limit' or 'response_format' beyond their names. The schema already provides constraints, so the description adds moderate value.

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?

The description clearly states the tool returns 'All live airborne flights from a specific country', which is a specific verb+resource. However, it does not distinguish from the sibling 'globalpulse_aviation_get_live_flights', which likely returns all flights without country filter.

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?

The description implies usage when you need flights filtered by country, but it does not explicitly mention when not to use it or suggest alternatives like the unfiltered sibling tool. Context is clear but lacks exclusions.

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