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

No annotations are provided, so the description carries the full burden of disclosing behavior. It describes what is returned but does not state whether the operation is read-only, requires authentication, or has side effects. It also does not clarify the structure or meaning of the requirements, leaving significant behavioral ambiguity.

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 a single, compact sentence that immediately conveys the core purpose. It is front-loaded with the verb and resource, and every word adds information. There is no waste.

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 zero-parameter tool with no output schema, the description gives a high-level list of what is returned, which is adequate but thin. It leaves unclear aspects like the exact format or how these requirement categories interrelate. The presence of sibling tools and the lack of usage guidance also reduce contextual completeness.

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 tool has zero parameters, so there is nothing for the description to explain about parameter semantics. Per the baseline for 0 parameters, this scores a 4. The description correctly avoids inventing parameters and focuses on the output.

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 clearly states the tool returns wallet requirements, enumerating specific categories (owner authentication, x402 payer, credential, adapter). The verb 'Return' is specific, and the resource is evident from the tool name and description. It distinguishes itself from sibling tools by focusing on requirements rather than configuration or contracts, though the jargon-heavy phrasing could be clearer.

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 versus alternatives. The description does not mention any use cases, prerequisites, or exclusions. With several sibling get_* tools, an agent would benefit from context on when wallet requirements are needed, but no such guidance is provided.

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