Verify Wallet Domain

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

The description discloses the key behavioral fact the annotations can't: this reaches out over the open web to fetch a TOML file, and success writes a trust-score contribution (explaining readOnlyHint=false despite the 'verify' name). The idempotent, non-destructive profile is consistent with the stated behavior. It does not mention failure modes or rate limits, keeping it short of a 5.

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?

Front-loaded with the core action and mechanism, then a short mechanism/precondition paragraph. Every sentence carries information, though the middle paragraph is slightly padded and the 'Returns' line duplicates the output schema.

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?

Given only two well-documented params, an output schema, and annotations, the definition covers what an agent needs: the external-fetch nature, the required TOML location and [ACCOUNTS] key, and the side effect on trust score. A note on failure cases (e.g., what happens if the file is absent or mismatched) would make it complete.

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?

Schema description coverage is 100% and both params are documented in-schema, so the baseline is 3. The description reinforces that the domain must host the TOML and that the wallet must appear in it, but adds no format or syntax detail beyond the schema.

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?

States a specific verb+resource (verify a wallet's domain ownership) and names the exact mechanism (XRPL Foundation xrp-ledger.toml at /.well-known/). This is clearly distinguishable from siblings like confirm_wallet_ownership or verify_nft_ownership, which cover different ownership proofs.

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?

It states the precondition for success (the domain must publish an xrp-ledger.toml listing the wallet under [ACCOUNTS]) and the payoff (10 pts toward trust score), which implies when to reach for it. However, it never explicitly says when to use this versus confirm_wallet_ownership or get_wallet_verification_challenge, so alternative selection is left to inference.

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