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

With no annotations present the description carries the full burden. It usefully discloses the supported chains and that calls are metered against a signed wallet (an auth/payment context that matters before calling), but says nothing about what the score means, its range, or what happens after the free quota is exhausted.

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 capability and supported networks, then the trial-call caveat. Nothing is padded, though the emoji adds no semantic value.

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 tool with no annotations, no output schema, and three parameters at 0% description coverage, the definition is thin: it omits the shape of the risk result and how to populate token vs address. The chain enumeration is the only substantive completeness it offers.

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 0% and all three parameters are undocumented. The description enumerates chain names, which partially informs the `chain` parameter, but it never explains the difference between `token` and `address` — the most likely source of a malformed call — nor the expected formats.

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?

"ERC-20 token risk score" is a specific verb+resource and the chain list makes the scope concrete. It does not, however, distinguish itself from nearby siblings such as x402-token-risk-report, x402-token-rugcheck, or x402-token-intel, leaving overlap for the agent to resolve.

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 description never says when to use this instead of the other token-risk/rugcheck siblings, nor what prerequisites exist. The only usage-adjacent information is a pricing note (5 free trial calls per signed wallet), which is not decision guidance.

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