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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions 'real-time monitoring' but does not explain what that entails, whether it is a read-only operation, what data it returns, or any side effects. This is insufficient for a tool with no other structured behavioral hints.

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 extremely brief and free of fluff, which is good for conciseness. However, it is a noun phrase rather than a full sentence, and while it is not verbose, the brevity comes at the cost of clarity. It earns a 4 for efficiency but loses a point for being under-specified.

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 there is no output schema and no annotations, the description must explain what the tool returns and how it behaves, but it does not. It only mentions the general domain (integrity monitoring) without providing any concrete details, making it incomplete for an agent to confidently invoke the tool.

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 tool has zero parameters, and the schema is empty (100% coverage trivially). According to the rubric, the baseline for 0 params is 4. The description does not need to add parameter meaning since there are none, and the tool's purpose is not parameter-dependent.

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 identifies RLUSD as the subject and mentions integrity monitoring and attestation verification, giving a clear topic. However, it lacks a specific verb (e.g., 'check' or 'retrieve') and does not differentiate from sibling tools like audit_verify or compliance_preflight, making the exact purpose somewhat ambiguous.

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 on when to use this tool versus alternatives. No context about scenarios, prerequisites, or conditions is provided, leaving the agent without clear direction on when this tool is the appropriate choice.

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