get_flight_tracks

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 the output shape (timestamped lat/lon/altitude/speed points) and the prerequisite of obtaining fr24_id first. It does not discuss limitations like track availability, retention, or pagination, but given the read-only annotation the added context is adequate.

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 two sentences with no filler. The purpose is front-loaded, and the prerequisite is presented as a clear second sentence. Every word contributes.

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?

For a single-parameter read-only tool with an output schema, the description covers purpose, parameter origin, and the primary prerequisite. The annotations handle the read-only and open-world aspects. Nothing essential is missing for an agent to call this tool correctly.

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 schema already documents flight_id as a hexadecimal string. The description adds value by explaining that the fr24_id must be obtained from specific sibling tools before use, which is useful operational guidance beyond the schema.

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's function: retrieving a detailed position track (series of timestamped lat/lon/altitude/speed points) for one specific flight. It explicitly ties the input to the FR24 flight ID, distinguishing it from list/search tools like search_flights and get_flights_in_zone by limiting scope to a single flight.

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 gives explicit guidance on when to use this tool: after obtaining the fr24_id from get_flight_data, search_flights, or get_flight_summary. It clearly communicates the prerequisite dependency. It does not, however, offer explicit 'when not to use' or alternative routing beyond the prerequisite mention.

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