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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false; the description adds operational context by explicitly stating 'No payment' and 'Does not submit txs.' This goes beyond the annotations by clarifying the on-ledger interaction model and that no transaction submission occurs.

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 two short sentences with no filler, front-loading the core record fields and then stating the safety constraints. It is compact, though jargon such as 'Bound...' and 'toml/merchant/verify URLs' makes it slightly less clear than it could be.

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?

For a zero-parameter read-only lookup, the description covers what the tool returns (the listed record fields) and what it will not do (pay or submit transactions). No output schema exists, but the listed fields give enough context to interpret the result; defining shorthand terms would improve completeness but nothing essential is missing.

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 input schema has zero parameters and schema description coverage is 100%, so there are no parameter semantics for the description to explain. The baseline of 4 applies because the description cannot add meaning where no parameters exist.

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 title and description clearly identify a read-only status/lookup for an XRPL publisher record, and the description enumerates the record contents (identity vs payTo, Domain, catalog SHA3-512, toml/merchant/verify URLs). It lacks an explicit verb like 'returns' or 'fetches,' and it does not differentiate from siblings by name, so it does not reach 5.

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 description makes clear that this operation is unpaid and does not submit transactions, which tells an agent it is a safe, non-mutating status query rather than a payment or tx operation. However, it never states when to choose this tool over sibling tools or names alternatives, so the usage guidance remains mostly implied.

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