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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only says 'Get', which implies a read-only operation, but it does not mention return format, pagination, potential need for permissions, or what happens if the pilot is not found. This is minimal and lacks transparency beyond the verb itself.

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 concise sentence with no filler words. It is front-loaded with the key action and resource. While it is short, it is not bloated, and the brevity is not penalized given the simple one-parameter tool. A slightly longer description could improve other dimensions without hurting conciseness.

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?

There is no output schema, so the description should explain what 'flight activity' contains or what the response looks like. It does not. It also fails to provide any context about time ranges, data granularity, or how it relates to similar tools. This is incomplete for an agent to invoke correctly and interpret results.

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?

The schema covers 100% of the parameter descriptions, with 'name' described as 'Name of the pilot'. The tool description adds no extra meaning beyond this, but the schema already provides sufficient clarity for the single parameter. Baseline 3 is appropriate.

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 uses a clear verb ('Get') and resource ('flight activity for a pilot'). It specifies the entity (pilot) and the general data type. However, 'flight activity' is somewhat ambiguous and does not distinguish it from siblings like get_flight_statistics, but it is not a tautology and conveys a direct operation.

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 provides no guidance on when to use this tool versus alternatives. It does not mention any context, exclusions, or mention related tools such as get_flight_statistics or get_aircraft_hours. A user or agent has no basis for choosing this over siblings.

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