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

No annotations exist, so the description carries the full behavioral burden. It signals a harmless, non-claiming operation, but does not say whether signing touches funds, requires the wallet to be unlocked/configured, what failure looks like, or that the signature is off-chain with no side effects.

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?

Two short sentences, front-loaded with the verification purpose, and the negative scoping clause ('Does not claim work') earns its place by preventing misuse as a claim action.

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 probe with no annotations or output schema, the description is only minimally sufficient. It omits what a successful vs failed probe returns and how the wallet parameter relates to the configured wallet, which an agent needs to call it correctly.

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 single required 'wallet' parameter has 0% schema description coverage, and the description does not clarify whether it expects an address, a wallet name, or an identifier of the already-configured CDP wallet. The phrase 'its configured CDP wallet' hints at a config selector but leaves the value format ambiguous.

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 names a concrete verb and resource: it verifies that a configured CDP wallet can sign an EIP-191 message. 'Does not claim work' separates it from the claim/submit siblings, though it never names the closest alternative (local_wallet_status).

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?

'Harmlessly verify' implies a preflight/capability check and 'Does not claim work' excludes the claim path, so the use case is inferable. However, it never states when to prefer this over local_wallet_status or the bountybook_auth_challenge flow, nor what must be true before calling.

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