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

The annotations say destructiveHint=true, but the description corrects the likely misreading: this files a request for review and does not perform deletion or export itself. That is real context an agent can't get from the annotations alone. It stops short of stating whether the submission is reversible, how to retry safely (the idempotency_key exists in schema only), or what the response returns.

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, front-loaded with the action and then the constraint. No filler and no repetition of the title.

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 9-parameter mutation with 11% schema coverage and no output schema, the description leaves almost all arguments undefined for the agent. It is adequate on intent and limits but not on how to construct a valid call.

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 only 11% (idempotency_key alone) across 9 parameters, so the description needs to carry the load and doesn't. Nothing explains the meaning of scope (the nine resource values), subjectKind, subjectLabel, or reason, and there is no hint that all 8 are required.

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?

States a specific verb and resource: 'File an export or deletion request for human review.' The two request kinds match the requestKind enum, and 'privacy_requests' distinguishes it from the sibling summer_privacy_requests_list without needing the schema.

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 gives a clear boundary about what happens after filing ('Cannot approve, perform or attest completion of the work'), which implies follow-up steps belong elsewhere. It never states when an agent should file versus check existing requests (summer_privacy_requests_list) or hand off to human tasks, so the positive trigger is left implicit.

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