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

No annotations provided, so description must cover behavior. It states multiple operations but does not disclose behavioral traits such as side effects, permissions, or rate limits. The deferral to describe_tool undermines transparency.

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?

Description is concise (3 sentences) and front-loads the purpose. However, the 'Menu ID:' prefix and the final sentence deferring to describe_tool add unnecessary verbiage. Still, generally efficient.

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?

Given the tool's complexity (multiple operations, 3 required parameters with no schema descriptions, no output schema), the description is highly incomplete. It fails to explain how parameters map to functionality and delegates to another tool. Lacks essential context for reliable use.

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?

Input schema has 3 parameters with 0% description coverage. The description does not explain the meaning of 'operation', 'value', or 'unit', nor does it list possible values or how they relate to the advertised capabilities. Utterly insufficient.

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's purpose: convert file sizes between decimal and binary units, compare, estimate transfer time, and compute fit. It uses specific verbs and resources, but does not explicitly differentiate from sibling tools like 'conversion_base_converter'.

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?

Minimal guidance on when to use this tool vs alternatives. Mentions capabilities but no context about when to use each operation or when not to use. Defers to describe_tool for full guidance, indicating lack of self-contained instructions.

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