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

With no annotations, the description carries the full burden, and it does so exceptionally well. It discloses what is deleted, what persists, the ordering of channel revocation, the 503 failure mode, repeatability, and that the response carries a remover command per measurement.

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 opening sentence is front-loaded and effective, but the body is dense and includes a cryptic reference to GET /api/coletas/serie and a convoluted 'That is why the answer carries remover' explanation. Most clauses carry behavioral value, but the structure is not as crisp as it could be.

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 destructive tool with no output schema, the description addresses key concerns: side effects, retention, retryability, error status 503, ordering, and even a hint of the response shape. It does not cover success status codes or not-found behavior, but the core contract is well specified.

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 input schema already documents the id parameter as a UUID v4 with a one-hour capability note, so schema coverage is 100%. The description does not add extra parameter-level details, which matches the baseline for fully covered schemas.

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 first sentence names the exact action and resource: 'Removes a device and every measurement on it, in one call.' This clearly distinguishes it from sibling delete_* tools that target narrower resources, and the later description reinforces what is owned and removed.

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 when to use it: when you want to remove a device and all its measurements in one operation rather than one call per measurement. It does not explicitly name alternative sibling tools or exclusion conditions, but the intended usage context is clear.

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