Get Wallet Verification Challenge

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

Adds traits beyond the annotations: the challenge is one-time (consistent with idempotentHint=false), expires in 30 minutes, requires the memo value as hex, and no private key is ever transmitted because the signed on-chain tx is the proof. These are operationally critical details an agent cannot infer from readOnlyHint/openWorldHint alone.

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?

Four short sentences, front-loaded with the action, then the mechanism, then the required follow-up call, then the expiry constraint. Every sentence carries information the agent needs to act.

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?

Covers the mechanism, the signing requirement, the follow-up tool, and the 30-minute TTL, and return values are covered by the output schema. It leaves minor gaps such as what happens if the challenge expires or is reused, but nothing required for a correct invocation 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?

Only one parameter, and the schema already documents wallet_address at 100% coverage, including the 'r...' format hint. The description adds no input-side syntax beyond that, so the baseline of 3 applies; the hex detail it mentions concerns the memo payload, not this parameter.

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?

'Request a one-time verification challenge to prove ownership of an XRPL wallet' states a specific verb (request), a distinct resource (verification challenge), and the scope (ownership proof for an XRPL wallet). It is clearly separable from siblings like confirm_wallet_ownership and verify_wallet_domain, which it does not duplicate.

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?

States when to use it (to prove ownership) and prescribes the follow-up: broadcast the AccountSet tx then call confirm_wallet_ownership() with the tx hash. No alternatives or exclusion conditions are given, so a 4 rather than a 5.

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