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

Annotations already declare destructiveHint=true and non-idempotence, so the safety profile is covered. The description still adds real behavioral context beyond the annotations: deletion 'requires approval by default', which tells the agent an approval step may be needed before execution. It stops short of stating recoverability or what happens to related data.

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?

Two short sentences with zero filler; the invocation trigger and the destructive/approval caveat are both front-loaded and each sentence earns its place.

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?

An output schema exists, so return values need not be described, and annotations cover the safety semantics. The description supplies the approval nuance, leaving only minor gaps such as when approval_id is conditionally required versus optional.

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 100% and both parameters are documented in the schema, so the description is not required to compensate. It adds no parameter detail of its own, so the baseline of 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?

The description states the action and resource ('a document removed'), and the tool name/title confirm a delete operation on documents, which cleanly separates it from documents.list and documents.upload. It is phrased as a trigger condition rather than a crisp verb+resource statement, but the intent is unambiguous.

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?

'When the user wants a document removed' gives a usable trigger condition for invoking the tool. However, it names no alternatives or exclusions and offers no guidance on preconditions beyond the approval note, so usage is only implied rather than fully specified.

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