get_station_users

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: no return shape, no pagination behavior for large user lists, no permission requirements, no indication of what an empty or unknown station_id yields. 'List all users' conveys only the bare operation.

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?

A single front-loaded sentence with zero padding or filler; the core operation leads immediately. It is efficiently sized, though so terse that nothing beyond the bare statement of purpose is communicated.

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 one-parameter read tool with no output schema and no annotations, the description is minimally viable: an agent knows what it does and what to pass. It omits any return-value expectation or pagination note, but with the schema fully covering the input there is no critical gap.

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 100% for the single station_id parameter, so the schema already documents it adequately. The description adds no format, ID-source, or validity detail beyond the schema, which is the baseline-3 case for a fully documented parameter.

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?

States a specific verb (List) and resource (users of a station), which is unambiguous and clearly distinct from siblings like get_station, add_station_user, or update_station_user_role. It does not explicitly name a sibling, but the scope is precise enough that an agent can select it confidently.

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?

There is no guidance on when to use this versus alternatives such as get_station_state or add_station_user; the only hint is the implied read-only listing semantics of 'List'. No prerequisites, no exclusions, no mention of whether the station must exist or be active.

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