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

No annotations are provided, so the description carries the full burden of disclosing behavior. It discloses nothing—no side effects, no return value, no operational details. The description is a label, not a behavioral specification.

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 not effectively so: every word is wasted repetition. It lacks any structural explanation and fails to earn its place. This is under-specification, not concise communication.

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 no output schema, no annotations, and a tautological description, an agent has zero information about what this tool returns or what it does. There is no way to correctly invoke or interpret the result. The definition is completely inadequate.

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?

There are zero parameters, so the empty schema fully captures the input semantics. No description is needed to explain parameters; the score is therefore the baseline 4. The tool's total lack of meaningful description does not affect this dimension because there are no parameters to document.

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 'Standard Scale: Standard Scale' is a pure tautology—it merely restates the tool name and provides no verb, resource, or action. An agent cannot determine what this tool does, let alone distinguish it from the massive list of sibling 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?

There is no guidance about when to use this tool, what problem it solves, or when to prefer an alternative. With hundreds of siblings, the lack of any usage context leaves the agent completely unable to select this tool correctly.

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