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

With no annotations, the description carries the burden and does disclose meaningful traits: the result is heuristic, costs $0.0200 USDC per call, is executed via POST to a specific x402 endpoint, and returns data directly. It does not describe failure modes, rate limits, or confirm the operation is a read-only scan.

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 purpose and scanned scope are front-loaded in one dense clause, followed by input and pricing details. It is compact and mostly earns its sentences, though the execution/pricing boilerplate is somewhat tangential to the core capability.

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 tool with no output schema and no annotations, the description is fairly complete: it implicitly lists the return contents (code, metadata, proxy status, risky selectors), specifies the input format, and documents cost and transport. Missing only error behavior and explicit read-only confirmation.

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% and there is a single parameter, so the schema already carries the semantics. The description merely restates the input ("token", alamat 0x…) without adding format, chain, or validation meaning beyond what the schema provides.

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 specific verb (imbas/scan) and resource (ERC-20 contract on Base) and enumerates exactly what is inspected: code, name/symbol/decimals/supply, EIP-1967 proxy, and risky selectors. It never names or contrasts a sibling, so it falls short of the top band despite being highly specific.

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?

Usage is only implied: an agent can infer you call this to vet a token address before interacting with it, but there is no explicit when-to-use/when-not guidance and no routing to alternatives like risiko or saring-token. The pricing and execution note adds context but not selection guidance.

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