Preview a payload profile

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the valuable behavioral context that no external seller API is called, reinforcing that this is a local, side-effect-free operation. It does not detail output format, but the annotation coverage lowers the burden.

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 a single, front-loaded sentence that names the action and the key constraint. Every word earns its place, with no filler 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?

The output schema and annotations cover return structure and safety, but the description leaves 'reviewed profile' undefined and does not clarify prerequisites or what rendering entails. It is adequate for a simple preview tool, but has clear informational gaps.

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% and the description does not explain either required parameter. The product parameter is partially clarified by the detailed MasterProduct schema, but profile_id has no added meaning, and the description fails to compensate for the low schema coverage.

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 renders/previews a profile and explicitly notes it does so without calling any external seller API, making the action and scope unambiguous. The verb 'Render' plus the resource 'reviewed profile' distinguishes it from external publishing operations.

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 phrase 'without calling any external seller API' implies a safe, read-only preview use case, but the description gives no explicit when-to-use instructions, prerequisites (e.g., the profile must be reviewed), or alternatives such as product_publish. Usage guidance is left largely implicit.

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