delete_users_by_id_block

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

Annotations already indicate destructiveHint=true, idempotentHint=true, and readOnlyHint=false. The description adds no additional behavioral context beyond the verb, such as authentication requirements, side effects, or reversibility. It does not contradict the annotations, but it also adds no value beyond what the annotations already convey.

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 exceptionally concise: one sentence for the action, the endpoint, and the parameter. It is front-loaded with the key verb and contains no filler or redundant information.

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 simple one-parameter tool with a complete parameter explanation and output schema present, the description is largely sufficient. It could explicitly mention the effect (removes an existing block) or note the inverse relationship to create_users_by_id_block, but the agent has enough 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?

The description fully explains the only parameter, id: 'The slug that identifies the user, or "me" for the authenticated user.' This goes beyond the input schema, which provides no description and has 0% coverage, so the description carries the full burden and does it well.

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 states a specific verb and resource: 'Unblock this user.' This clearly conveys the action. However, it does not explicitly distinguish the tool from the sibling create_users_by_id_block, relying on the reader to infer that unblocking is the inverse of blocking.

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, nor any prerequisites. It merely states the action itself without any context about when unblocking is appropriate.

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