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

With readOnlyHint=true already covering the safety profile, the description adds real behavioral value: it discloses the return payload (interaction JSON, fresh ROLA challenge when something is signed, the validation problems the wallet would reject, and the matching radix-connector call) even though no output schema exists. It omits permission/auth prerequisites and any rate or size limits, so it is strong but not exhaustive.

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 purpose is front-loaded in the first clause, followed by the scope enumeration and then the return/next-step sentence. The opening sentence is long and dense with the auth-mode list, but every clause carries information and there is no filler.

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 9-parameter tool with nested objects, enums, and no output schema, the description covers purpose, request scope, and return contents adequately. Remaining gaps are minor — no explicit mention of error behavior beyond validation problems or of prerequisites relative to setup_wallet_connector.

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, but the description adds cross-parameter meaning beyond the schema — e.g. that a request may ask for no address at all and that certain modes need a persona. This helps an agent reason about valid parameter combinations the flat schema does not spell out.

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 and resource (builds the exact schema-v2 wallet interaction a dApp sends to the Radix Wallet) and enumerates the request categories it covers. It also names the sibling verify_rola_proofs as the follow-up verification step, so an agent can place it in the workflow without opening the schema.

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 enumerated auth modes and the note that a request may ask for NO address give clear context for when each configuration applies, and it points to verify_rola_proofs for the signed answer. It does not explicitly contrast with near siblings like setup_wallet_connector or check_signing_request, so no true exclusions are stated.

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