FlightDB

Flight_list_flights

Read-only

Paginated flight rows with optional filters: aircraft id substring, departure/arrival airport or city substring, country substrings, date range, sortBy (Flight scalar field), sortOrder.

Returns { data, total }. Each row includes nested departure/arrival airport { id, name, municipality, timezone }.

A3.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds genuinely non-obvious behavior: that filters are substring matches rather than exact equality, that results are paginated, and that the response is shaped as { data, total } with nested airport objects — details an agent cannot get from the annotations.

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

Conciseness4/5

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

Two sentences, front-loaded with the core action and filter inventory, then the return shape. Efficient, with only the return-format sentence being arguably redundant given an output schema exists. No filler or repetition of the tool name as prose.

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?

With 14 optional parameters and an output schema, the description covers the main filter families and the response envelope well. Gaps remain around pagination bounds (limit max 100, page starts at 1) and routing versus the aggregate siblings, but these are secondary for a filter-driven list tool whose annotations and schema carry safety and structure.

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 coverage is only 43% across 14 parameters, so the description must compensate and it does so partially: it clarifies substring semantics for aircraft id, airport/city, and country filters, and explains sortBy is a 'Flight scalar field' paired with sortOrder. It omits page/limit (despite calling the tool 'paginated'), flightId, and icaoType, leaving several of the undocumented parameters unexplained.

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 (list) and resource (flight rows) plus its paginated nature and the filter dimensions available, so an agent understands what it returns. It does not differentiate itself from aggregate siblings such as Flight_flights_by_country, Flight_flights_by_year, or Flight_top_routes, which also expose flight data, so the agent must infer that this is the raw row-level listing.

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 'optional filters' implies this is the general-purpose query tool for flight rows, which hints at usage. However, there is no explicit guidance on when to prefer this over the many aggregation siblings (by_country, by_distance, by_year, top_routes), nor any stated prerequisites or exclusions.

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