gateway_approval_decide

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

The description adds an explicit permission requirement, 'Requires approvals:write,' which is meaningful because annotations provide no read-only, destructive, or other behavioral hints. However, it does not disclose the side effects of the decision, whether it is reversible, or what happens when information is requested.

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 short, dense, and front-loaded with the core actions followed by the access requirement. Every sentence contributes useful information, though the compactness leaves room for missing detail.

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?

The description is not complete for a decision-making mutation tool: it omits the semantics of the decision payload, the effect of requesting information, possible constraints, and the meaning of the optional comment field. An output schema exists, but the decision workflow and side effects remain underspecified.

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?

With 0% schema description coverage, the description must compensate, but it only hints at possible decision types: approve, reject, or request information. It does not explain approval_id format, the exact accepted values for decision, the purpose of comment, or how decision_payload_json should be structured.

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 tool approves, rejects, or requests information on an approval, providing a specific action and resource. It does not explicitly differentiate itself from sibling tools like gateway_approval_comment or gateway_admin_access_request_decide, but the name and intended action make it clear enough.

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 no guidance on when to use this tool versus alternatives such as gateway_approval_comment or gateway_admin_access_request_decide. It only states the required permission, which is useful but not usage guidance.

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