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

With no annotations provided, the description carries the full burden of explaining behavior. It mentions the output is an XML structure and regulatory standards (MiCA/DORA), but does not disclose side effects, return format, or whether it is a read-only operation. This is insufficient for a tool with no annotations.

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 very concise, three short sentences with no wasted words. It briefly states the purpose, target audience, and regulatory readiness. However, it could be more informative without becoming verbose, hence not a 5.

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 only a vague description, the tool is under-specified. It does not clarify what the tool returns (e.g., a static template, a schema, a sample), how to use it, or why it differs from siblings. For a zero-parameter tool, more context about its output and use case is needed.

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?

There are zero parameters, and the schema coverage is vacuously 100%. Per the rubric, a baseline of 4 applies for 0-parameter tools. The description adds no parameter details because none exist, but this is appropriate.

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 an ISO 20022 mappable XML structure for RLUSD evidence, but lacks a clear verb (e.g., 'generates', 'returns', 'validates'). It is not a tautology and hints at the resource, but the exact action is vague.

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?

No guidance is given on when to use this tool compared to siblings like xrpl_rlusd_integrity or xrpl_compliance_check. The description is purely descriptive and does not state use cases, prerequisites, or alternatives.

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