convert_volume

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

No annotations are present, so the description must carry the burden of behavioral disclosure. It only states the basic function without any details about acceptable units, precision, error handling, or side effects. The description is minimally transparent.

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 very short—one sentence—which is concise but at the expense of essential information. It is not well-structured for quick comprehension as it lacks any structural elements like bullet points or examples. While concise, it sacrifices completeness.

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 lack of output schema and annotations, and only a one-sentence description, the tool definition is contextually incomplete. An agent would not know what units are supported or how to format parameters, making it difficult to use correctly without additional knowledge.

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?

The input schema has no descriptions for its three parameters (value, from, to). The description adds no information about parameter formats, expected unit strings, or value ranges. The agent has no guidance on how to specify units or the numeric value.

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 'Convert between volume units.' clearly identifies the tool's function and distinguishes it from sibling conversion tools by specifying 'volume units', which sets it apart from area, length, temperature, etc. The verb 'convert' is specific and the resource 'volume units' is well-defined.

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 usage guidance is provided. The description does not mention when to use this tool over alternatives, nor does it give examples of valid units or any prerequisites. Given many sibling conversion tools, explicit guidance would be beneficial.

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