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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description contributes the concrete scope of destruction — uploads and sheet — which is real added value. It stops short of stating whether the character request record itself is removed, whether the action is reversible, or whether anything else (e.g. face checks, looks) is affected.

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?

Five words is not concision here, it is under-specification: the single sentence omits the object of the action and any consequence detail. There is nothing extraneous, but the description is too thin to earn its place as the primary semantic signal.

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?

This is a destructive, irreversible-sounding operation on a workflow entity, and the description never says what remains after the call, whether the parent request survives, or what the caller should expect. Annotations cover the read/write and destructiveness flags, but the description should carry the domain consequences for a delete-style tool.

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 single parameter request_id is fully documented in the schema (100% coverage) including the charreq_ prefix convention. The description adds no further meaning about the identifier or how to obtain one (e.g. via list_character_requests). With the schema doing the work, baseline 3 applies.

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?

"Deletes its uploads and sheet" names a verb and two affected artifacts, but the pronoun "its" has no antecedent in the description itself — the agent must read the tool name or title to know it operates on a character request. The purpose is inferable but not stated explicitly, so it lands at vague rather than clear.

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 discard versus keep (the sibling keep_character), when a request is eligible for discarding, or what state the request must be in. The agent is given no conditions or alternatives, only a bare statement of effect.

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