Verify Wallet Domain

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

The description discloses a meaningful side effect: verification 'contributes 10 pts to the wallet's trust score,' which aligns with readOnlyHint=false. It also explains the external dependency on the domain publishing a well-known file. Annotations already cover idempotency and non-destructiveness, so the description adds useful behavioral context without redundancy.

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 concise and well-structured: a one-sentence purpose, a short mechanism explanation, and a clear return-value list. Every sentence adds relevant information and the key purpose is front-loaded.

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 two-parameter verification tool with a rich output description and annotations covering idempotency and side effects, the description is largely complete. It explains prerequisites, the verification mechanism, the trust-score impact, and return values. It could mention failure modes or when the verification would return false, but that is a minor gap.

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%, so the baseline is 3. The description reinforces the meaning of both parameters by explaining that the domain must publish an xrp-ledger.toml listing the wallet, but it does not add substantial new semantic detail beyond the schema's own parameter descriptions.

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 ('Verify') with a clear resource ('XRPL wallet is owned by a specific domain') and names the exact standard (XRPL Foundation xrp-ledger.toml). It distinguishes itself from related verification tools like confirm_wallet_ownership by focusing on domain-based verification via a published toml file.

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 implies when to use the tool: when a domain claims ownership of a wallet and publishes the required xrp-ledger.toml file. However, it does not explicitly mention alternatives or state when not to use it, leaving the agent to infer the distinction from sibling names.

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