delete_fictional_user

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

The description only repeats that the tool deletes, which is already conveyed by the destructiveHint annotation. It adds no additional behavioral context such as whether deletion is permanent, cascading, or requires special permissions. The openWorldHint is not addressed.

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, front-loaded sentence with no filler words. It is appropriately concise for a simple delete operation, every word contributes to the meaning.

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?

The tool is simple (one parameter, no output schema) and annotations provide destructiveness and idempotency hints. However, the description does not clarify potential side effects, prerequisites, or permanent nature, leaving some ambiguity for a delete operation.

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 fully documents the only parameter (fictional_user_id) with a clear description. Since schema coverage is 100%, the baseline is 3, and the tool description itself adds no extra parameter meaning.

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 'Delete a fictional user' uses the specific verb 'Delete' and clearly identifies the resource (fictional user), distinguishing it from other delete_* tools in the sibling list. It precisely states what the tool does without ambiguity.

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 or any exclusions. It does not mention other fictional user operations (create, update, get, list) or related delete tools, so the agent receives no explicit usage context.

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