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

No annotations are provided, so the description carries the full burden. It usefully discloses default transfer-time windows (2 and 5 hours), which affect results when those parameters are omitted, but it does not describe the return format, pagination, or whether the query is read-only.

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 a single front-loaded sentence that states the purpose and then lists the input dimensions, followed by default notes. It is dense but wastes no words and puts the core operation first.

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 five-parameter query tool with no annotations and no output schema, the description covers purpose, parameter mapping, and time-unit defaults. However, it omits any description of the returned flight information and does not explain how place names should be formatted, leaving the agent to infer return shape and input 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 description coverage is 0%, so the description must compensate. It names all five parameters in Chinese and maps them to departure, transfer, and destination places, and crucially clarifies that min/max transfer time are in hours with defaults of 2 and 5, adding meaning beyond the bare numeric schema defaults. It still doesn't specify the expected format for place values.

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 states a specific verb ('查询' query) and resource ('中转航班' transfer flights), and enumerates the three-place plus time-window inputs that define the query. It differentiates itself from generic flight siblings like getAirportFlights or searchFlightRoutes by focusing on connecting itineraries, though it doesn't name any sibling explicitly.

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 explains what inputs drive the query but offers no explicit when-to-use guidance, no alternatives, and no exclusions. An agent can infer the tool is for connecting-flight lookups, but it must still discover on its own that searchFlightRoutes or getFlightInfo are not the right choice.

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