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

With no annotations, the description carries the full behavioral burden. It conveys that data is historical and tamper-evident via SHA-256 hashing, which is useful context, but says nothing about return volume, pagination, freshness, or auth requirements. For a zero-parameter tool with no schema hints, this is a significant gap.

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?

A single front-loaded sentence with no filler sentences. The double parentheticals ('(historical)' and '(tamper-evident)') add mild clutter but the whole thing is compact.

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?

No output schema and no annotations mean the description is the only source of information, and it omits what is actually returned (a list of anchors? a single record?) and any time-range or count expectations. For a simple zero-param read tool the omission is tolerable, but it leaves real gaps.

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 takes zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies; no parameter-level confusion is possible.

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 names the resource (RLUSD on-chain attestation anchoring) with a scope tag '(historical)' and a property qualifier ('tamper-evident'), but never states the action. 'Anchoring' reads as a noun describing the data rather than a verb, so an agent cannot tell whether this lists anchors, verifies them, or creates them. It also does not differentiate itself from the many nearby xrpl_rlusd_* siblings such as xrpl_rlusd_integrity or xrpl_rlusd_cci.

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 indication of when to call this tool versus any of the ~11 other RLUSD siblings. The '(historical)' tag hints at a temporal scope but no exclusion, prerequisite, or routing guidance is given.

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