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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It hints that the tool returns data (via 'data: ...') but does not disclose whether it is read-only, requires special permissions, or how it behaves in terms of rate limits or response structure. The listed attributes (freshness scoring, confidence levels) are more about data content than behavioral traits.

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 concise, only two sentences, and front-loads the main idea. It lists several attributes efficiently without unnecessary fluff. However, some terms feel buzzword-like, slightly reducing clarity.

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?

With no output schema and no annotations, the description must be more comprehensive to stand alone. It fails to explain what the agent will receive, how the data is structured, or the meaning of key terms like 'freshness scoring' and 'confidence levels'. For a supposedly enterprise-grade tool, the description is insufficiently informative.

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 input schema is empty with 100% coverage. According to the rubric, a baseline of 4 applies for 0-parameter tools. The description does not need to add parameter semantics since there are none to document.

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 indicates the tool provides RLUSD enterprise-grade data, mentioning several features like freshness scoring and compliance flags. However, it lacks a specific verb (e.g., 'get', 'list', 'query') and doesn't clearly distinguish itself from closely related siblings like xrpl_rlusd_integrity or xrpl_rlusd_anchor. The purpose is clear in a general sense but vague in execution.

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?

The phrase 'Built for regulated institutions' gives a target audience but does not specify when to use this tool versus the many RLUSD-related siblings. There is no mention of alternatives or exclusions, leaving the agent without clear guidance on tool selection.

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