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

Although no annotations exist, the description discloses the core behavior: the input is a numeric value and the return is bounded within [min, max]. It also clarifies the min/max are optional. This is sufficient for a simple pure math utility.

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 and gets to the point. The leading 'Clamp:' label is slightly redundant, but the rest of each sentence adds 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?

For a tool with no annotations, no output schema, and an empty input schema, the description is incomplete for correct invocation. It also does not mention the closely related sibling x402-clamp-value, so an agent may not know which clamp tool to choose.

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 zero properties, so the description must carry the entire parameter-definition burden. It mentions 'value plus min and/or max' but gives no parameter names, types, ordering, or JSON mapping, leaving an agent unable to construct a valid invocation from the schema or description.

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 verb and resource: clamp a numeric value to a range. It also explains the operation and result. However, the near-identical sibling x402-clamp-value means the description does not fully differentiate between the two.

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 is given on when to use this tool versus alternatives like x402-clamp-value or map-to-range. The phrase 'Provide value plus min and/or max' implies usage but does not explain selection criteria or prerequisites.

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