Get Wallet Verification Challenge

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

The description adds valuable behavioral details beyond the annotations: the challenge is one-time, expires in 30 minutes, no private key is ever transmitted, and the proof mechanism relies on an on-chain AccountSet transaction. This meaningfully informs an agent about how the tool behaves and what actions follow.

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 well-structured and front-loaded with the core purpose, followed by the verification flow, expiry, and return values. The Returns list is slightly redundant given that an output schema exists, but every sentence otherwise contributes necessary context.

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 single-parameter read-only challenge request, the description is complete: it explains the cryptographic proof model, the exact next step, expiry, and returned fields. An agent has everything needed to invoke the tool and understand the expected workflow.

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 already documents the single wallet_address parameter at 100% coverage, including the expected r... format. The description does not add additional parameter-level semantics beyond that, so the baseline score of 3 applies.

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 uses a specific verb ('Request'), a clear resource ('one-time verification challenge'), and a precise purpose ('prove ownership of an XRPL wallet'). It distinguishes itself from the sibling confirm_wallet_ownership by positioning itself as the first step and naming the follow-up call.

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 clearly states when to use it: before verifying wallet ownership, and it directs the agent to call confirm_wallet_ownership after broadcasting the transaction. It lacks explicit exclusions or comparison against alternative verification tools, but the usage context is unambiguous.

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