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

No annotations are provided, so the description carries the full disclosure burden, yet it says nothing about pagination, default limit behavior, ordering, or result size. All it conveys is that this is a retrieval operation, which the name already implies.

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 short sentence with no padding, so it is concise and front-loaded. The weakness is under-specification rather than verbosity.

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 4-parameter query tool with no annotations, no output schema, and 0% parameter coverage, the description is far too thin. An agent has no information on filtering behavior, defaults, or results without inferring from the XRPL API domain.

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?

Four parameters with 0% schema description coverage: limit, account, ledger_index_min, and ledger_index_max are all undocumented in both schema and description. The description does not explain the ledger-range filtering or limit semantics at all.

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 states a specific verb and resource ('Retrieve XRPL transaction history for an account'), which is clear enough to distinguish a history-list operation from a single-transaction fetch. However, it never names or contrasts with the sibling n9t2_xrpl_tx or n9t2_xrpl_account_info, so the differentiation must be inferred.

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 the sibling n9t2_xrpl_tx (single transaction) or n9t2_xrpl_account_info, and no mention of prerequisites. The only implied usage is 'you have an account and want its transactions'.

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