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

There are no annotations, so the description carries the full burden. It discloses scope boundaries and the multi-airport behavior, but does not explicitly state read-only semantics, response format, or any data freshness/availability caveats. For a query tool this is adequate but not rich.

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 efficiently structured: main capability first, then usage scenarios, then conversion rules, then exclusions. Every sentence carries useful decision information and there is no redundancy.

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 three-parameter list-query tool with full schema coverage and no output schema, the description is nearly complete. It covers input conversion, multi-airport ambiguity, typical user intents, and exclusions. It does not describe the output structure, but the relevant fields are implied by the usage examples.

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%, so the schema already documents all three parameters with formats and examples. The description adds value by explaining how city names should be converted to depCode/arrCode and how to handle cities with multiple airports, which goes 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?

Description states a specific verb and resource: querying an airport-pair flight list by departure, arrival, and date. It distinguishes itself from siblings by explicitly listing what it is not for, such as real-time status, prices, booking, weather, and flight paths.

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?

Provides explicit when-to-use guidance with concrete user query examples, plus a conversion rule for city names to airport codes and a multi-airport handling policy. It also names exclusions that route the agent away from sibling tools.

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