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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing: no output format, no computation semantics, no determinism or error behavior for an unannotated tool.

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 text is short, but this is under-specification rather than conciseness: it repeats the name verbatim instead of front-loading real information. Brevity here costs the agent everything it needs.

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 an unannotated tool with no output schema and two vaguely described parameters, the description supplies no operational context at all – an agent has no basis to call this correctly.

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 description coverage is 100% (two parameters, both with descriptions), so the mechanical baseline is 3. However, the schema text itself is boilerplate ('Value to process', 'Period to process'), and the description adds zero meaning about what 'value' or 'period' denote – the value holds only because the schema exists at all.

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' – the tool name restated twice, with no verb describing an operation. It hints at a waveform topic but gives no indication whether it generates, plots, or analyzes a sawtooth wave, so an agent cannot distinguish it from siblings like x402-square-wave or x402-triangle-wave.

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 whatsoever about when to use this tool, what inputs it expects, or which sibling waveform tool to pick instead. Nothing in the text implies a usage context.

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