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

With no annotations, the description carries the full burden and does disclose important behavior: the four data sources, the verdict categories, per-flag provenance, and the paid x402/USDC access model. It still omits side effects/permissions and any error or rate-limit behavior, but the core operational context is unusually strong.

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 definition is a single front-loaded sentence that puts the verdict and sources first, then the payment detail. It is dense but not wasteful; the arrow notation is compact and clear.

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 simple two-parameter read-style tool with no output schema, the description covers the key inputs indirectly, the data sources, the output taxonomy, provenance, and pricing. It is not fully complete because it does not describe response structure or failure modes, but an agent can 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?

Schema description coverage is 100%, and the schema already documents both the chain values and the address format. The description adds no parameter-specific meaning beyond that, so the baseline of 3 applies.

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 concretely states the resource (wallet risk verdict) and the specific sources used, plus the three possible outcome labels. It does not explicitly distinguish itself from siblings like wallet-status or defi-risk-basic/deep, so an agent must infer the boundary.

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 when-to-use or when-not-to-use guidance, and no named alternative tool. An agent must infer that this is for wallet-level risk screening rather than transaction or protocol risk.

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