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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool produces a multi-chain profile and mentions a 5-call free trial, but does not disclose whether the operation is read-only, what data is returned, whether registration or authentication is required, or any rate-limit behavior beyond the trial.

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 very brief and purpose is front-loaded in the first phrase. The free-trial sentence is arguably promotional but does not create significant bloat. It is concise, though the brevity leaves out useful detail.

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 no output schema, no annotations, and a small but ambiguous two-parameter input, the description is not complete enough. It omits return-value expectations, parameter selection logic, and differentiation from the many wallet-related sibling tools, leaving an agent with insufficient context to invoke it reliably.

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 coverage is 100%, so each parameter already has a basic description ('Wallet to process', 'Address to process'). The tool description adds no disambiguation between the two parameters, whether they are aliases or complementary, or which one should be provided.

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 identifies the tool as providing a 'Multi-chain wallet profile', which is a clear resource and scope. However, it lacks an explicit verb and does not distinguish it from closely related sibling tools such as x402-wallet, wallet-scan, or wallet-report.

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?

There is no guidance on when to use this tool instead of alternatives, no exclusions, and no mention of the wallet/address distinction. The only additional note is about free trial calls, which is a billing/limit detail, not a usage guideline.

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