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

Annotations already flag destructiveHint=true, idempotentHint=true, readOnlyHint=false. Beyond that, the description adds the auth/scope requirement, an optimistic-concurrency contract ('at its expected revision'), and concrete retry guidance ('Preserve request_id and payload on retries'). It doesn't spell out what state is destroyed or the error behavior on revision mismatch.

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?

Three short sentences, front-loaded with the action and outcome, then preconditions, then retry advice. Every clause carries information; nothing is padding.

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?

With no output schema, 'returns the resulting state' gives a minimal return hint, and the description covers identity, scope, concurrency, and retry. It leaves entry_id semantics and revision-mismatch handling unaddressed, minor gaps for a well-annotated mutation 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?

Schema coverage is 0% across three required params, so the description must compensate. It usefully ties request_id to retry/idempotency and implies expected_revision is a concurrency guard, but entry_id is never explained and no format or failure semantics are given.

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 names a specific verb+resource ('Retract an own review') and narrows scope to the caller's own review at a given revision. This cleanly distinguishes it from siblings like retract_comment and retract_vote, and from write_review.

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?

It states the prerequisite context clearly: a connected identity and the community:review scope are required. It does not, however, say when to choose retraction over an alternative (e.g., apply_correction or edit flow) or any explicit when-not condition.

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