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

The description discloses no behavioral traits. As a placeholder, it doesn't mention side effects, authentication needs, or other important behaviors. No annotations exist to compensate.

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 but lacks substance. It is concise only because it is a placeholder, not because it efficiently conveys useful information.

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 insufficient for real use. It provides no details about return values, error handling, or any context beyond being a template. The tool is not operational as defined.

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?

Although schema coverage is 100%, the description adds no meaning beyond the schema's parameter descriptions. It doesn't explain how parameters affect the API call.

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 is vague, stating it's a placeholder for an API call. It doesn't specify what resource or action it performs, nor does it distinguish from sibling tools like manage_file or process_order.

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?

No guidance on when to use this tool versus alternatives. The description fails to provide any context about appropriate usage scenarios.

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