Signed advisory dispute ruling from a deterministic rubric (PAID $2.00)

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

Annotations already declare the operation is a non-read-only, non-idempotent, open-world call, and the description usefully adds that it is a paid call at $2.00 via x402 on eip155:8453/base USDC and the remote POST route. It does not explain what 'advisory' means for downstream use, whether repeated identical calls can differ despite 'deterministic rubric' (idempotentHint=false), or what happens on unparseable claims beyond the schema hint.

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?

Only two sentences, but the first is a verbatim repeat of the title, so roughly half the text carries no incremental information. The payment/route detail is front-loaded and useful, but the definition is under-specified rather than efficient.

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?

Downgraded to 3 in spirit: the tool has an output schema and full schema coverage, so return values and parameters need not be re-explained. Still missing is why a caller would choose this ruling service over the many sibling verdict tools and what the advisory determination binds, leaving the definition incomplete for selection despite being structurally adequate.

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%, so the baseline is 3 and each nested object (claim, policy, contract, evidence) is already explained in the schema. The description adds no parameter meaning beyond that, so it neither compensates nor detracts.

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 first line names a concrete artifact (a signed advisory dispute ruling) produced by a deterministic rubric, which is more than a bare restatement of the name. However, it is verbatim the tool title, and it gives no differentiation from adjacent verdict/attestation siblings such as v1_verdict_agent, v1_synthesis_verdict or v1_decision_attest, so an agent cannot tell which one to pick from purpose alone.

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 statement of when to call this versus the many other verdict/ruling tools, no prerequisites, and no exclusions. The only usage-adjacent detail is the route and payment line, which is about mechanics rather than decision criteria.

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