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

Annotations already indicate readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds the verified-domain prerequisite and the review-timing constraint, which are useful. However, it does not disclose what happens on approval (e.g., immediate publication, potential failure modes) or any side effects beyond the act of approving.

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 two sentences, front-loads the core action, and then adds constraints. Every word earns its place; there is no fluff or repetition.

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 five required parameters, no output schema, and zero parameter descriptions, the description is far from complete. It leaves the agent without an understanding of what the parameters represent or what the tool returns. While the purpose and preconditions are clear, operational details are missing.

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 0%, so the description must explain the five parameters. It does not. The only vague link is 'exact draft revision' which points to the 'revision' parameter, but it fails to clarify the meaning of 'reference', 'listing_token', 'approver_role', or 'schema_version'. This is a significant gap.

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 clearly states the action: 'Approve publication of the exact draft revision on behalf of the company.' It identifies a specific verb, resource, and scope. It does not explicitly contrast with sibling tools, but the purpose is unambiguous enough to distinguish it from the other listing-related tools.

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 gives explicit preconditions: 'Requires a verified domain' and 'Only call after the company has reviewed the draft.' This tells the agent when it is appropriate to use the tool, though it does not mention alternative tools or when to avoid it beyond these conditions.

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