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

No annotations are present, so the description carries the full burden of disclosing behavior. It discloses nothing: no return format, output characteristics, side effects, or constraints. The repetitive text adds no behavioral insight.

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 tiny but redundant, repeating 'Sawtooth Wave' twice. This reads as a placeholder rather than a deliberately concise, information-dense explanation. Under-specification is not the same as conciseness.

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?

The tool has no output schema and no annotations, so the description must explain at least what the tool returns or how it behaves. It does neither, leaving an agent completely in the dark about how to invoke this tool or interpret its result, especially among many similar waveform siblings.

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 there are no parameters to document. The 0 params baseline of 4 applies; the description cannot add meaningful parameter semantics when none exist. A higher score would require additional context beyond the schema, which is not present.

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 is 'Sawtooth Wave: Sawtooth Wave', a verbatim restatement of the tool name with no functional information. It does not say what the tool does, and amid siblings like x402-square-wave and x402-triangle-wave, it provides no way to distinguish which waveform tool is which.

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 inputs to provide, or how it differs from alternatives. The description contains zero usage context whatsoever.

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