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

No annotations are provided, so the description carries the full behavioral burden. It does disclose a cost signal ('$0.01 x402'), which is useful, but it says nothing about whether the operation is read-only, how payment is handled, whether the verdict is cached or generated on demand, or what signing/verification implies.

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 definition is a single short fragment with no wasted words, but it is under-specified rather than appropriately concise. Jargon such as 'x402' and 'precomputed signed verdict' is packed in without enough context for an agent to act confidently.

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 no annotations, no output schema, and an undocumented parameter, the description is not complete enough. An agent still lacks the verdict's contents, the meaning of 'signed', payment mechanics, task_id requirements, and how this tool relates to its 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?

Schema description coverage is 0% for the single task_id parameter, and the description only implies 'for a task' without explaining format, whether it is truly required (schema marks zero required parameters), or what happens if omitted. It does not compensate for the undocumented parameter.

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 phrase 'Precomputed signed verdict for a task' does identify a resource (a verdict) and a qualifier (precomputed, signed), so the general purpose is inferable. But it is a noun phrase rather than a clear action, and 'x402' plus 'precomputed' are ambiguous, with no explicit differentiation from parity_probe beyond an implied retrieval-vs-computation distinction.

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 explicit when-to-use or when-not-to-use guidance, and no alternative is named. 'Precomputed' weakly implies using this instead of computing a fresh result via parity_probe, but that inference is left entirely to the agent.

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