conversion_miles_to_km

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

No annotations are provided, so the description carries the full disclosure burden. It does not state that the operation is a pure, side-effect-free function, nor does it mention precision or rounding behavior. For a trivial arithmetic conversion these omissions are minor, but nothing behavioral is affirmatively disclosed.

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?

A single front-loaded sentence with no filler; for a one-parameter utility this is an appropriate size. It is efficient if slightly terse.

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?

An output schema exists, so the return value need not be explained, and the input unit is established by the description. For a trivial unit conversion the definition is essentially complete, with only precision/range details left unspecified.

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 coverage is 0% — the single 'value' parameter is undocumented in the schema, described only as 'Value'. The description compensates by indicating the input is a distance expressed in miles, which adds real meaning over the schema, but it does not address accepted ranges or precision.

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?

States a specific verb (Convert), the resource (a distance), and the exact direction (miles to kilometers), which distinguishes it from the sibling conversion_km_to_miles without needing to name it. It is clear and unambiguous, though it never explicitly references the inverse tool.

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 explicit when-to-use or when-not-to-use guidance is given, nor are alternatives named. However, the tool's purpose is so narrow and self-evident from the name and description that the intended usage is strongly implied.

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