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

The annotations already communicate that the tool is read-only, idempotent, and non-destructive. The description adds the return concept but provides no extra behavioral context such as output structure, locale sensitivity, or any side effects. No contradiction with annotations.

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 with no filler. Every word contributes to understanding what the tool returns.

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 tool is simple and the annotations cover safety, but there is no output schema and the description does not specify the shape of the returned fields or how locale changes the result. It is minimally adequate but leaves small 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 mention the locale parameter or its effect on the returned fields. The schema itself does document the enum and default, so the parameter is not completely opaque, but the description adds no parameter-level meaning.

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 uses a specific verb "Return" and identifies the resource: the fields needed to prepare a structured production brief. This makes the tool's purpose clear, though it does not explicitly distinguish it from sibling tools such as get_deliverables.

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 intended use is implied by the resource name and description: retrieving fields needed for a production brief. However, there is no explicit guidance on when to prefer this tool over siblings, when not to use it, or how locale affects the output.

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