vote_for_station

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

With no annotations, the description carries the full behavioral burden. It does disclose the key side effect—increments the public vote counter—which is helpful and not misleading. However, it does not state whether votes are idempotent, whether repeated votes are tracked, or whether any authentication or rate limiting applies.

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 very brief and front-loaded: the main action is in the first five words, and the important side-effect note is clearly appended. Every sentence adds distinct information, and there is no filler or repetition of the tool name.

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 state-changing tool with no annotations, no output schema, and one poorly documented parameter, the description leaves important operational details unspecified: return value, error behavior, timeout semantics, and vote-counting rules. It is functional but only minimally complete for an agent deciding how to invoke it correctly.

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 for the undocumented parameters. It gives no explanation of the timeout parameter and only indirectly hints at station_uuid via the endpoint path {uuid}. The parameter names are somewhat self-explanatory, but the description adds almost no semantic value beyond what the schema already shows.

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 clearly states the action ('Vote'), the resource ('a station'), and the HTTP endpoint. It also includes the key differentiating detail that the action increments the public vote counter, which separates it from sibling tools like register_station_click and the various search/list tools.

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 gives no guidance on when to use this tool versus alternatives. It does not mention that register_station_click is for clicks, that get_top_voted_stations is for reading results, or any prerequisites or constraints such as whether the user must be logged in or how many votes are allowed.

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