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

With no annotations, the description carries the full burden. It does disclose that the tool verifies source code, ABI, and proxy detection via BaseScan, giving some behavioral detail. However, it does not explicitly state that it is read-only, what happens if the contract is not verified, or whether network access is involved.

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?

A single, concise sentence that front-loads the action and scope. Every phrase adds meaning, leaving no redundant or vague language.

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?

The tool is simple (one param, no output schema), but the description omits what the agent should expect as a result (e.g., boolean, detailed report, or error if unverified). It covers the input scope but not the output contract, which is a gap given the absence of an output schema.

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 only parameter, contract_address, is implicitly explained by the description ('Verify Base smart contract'), and its role as an address is self-evident. There is no schema description coverage, but the tool name and description ensure basic understanding. Details like address format or chain constraints are not 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 clearly states the verb 'Verify' and the resource 'Base smart contract', and it enumerates specific aspects (source code, ABI, proxy detection) that distinguish it from the sibling tools, which focus on yields, gas, and other chain metrics.

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 tool's purpose is immediately clear from the description: it is for verifying contracts on BaseScan, which is a distinct use case from the DeFi and analytics tools listed as siblings. No explicit exclusions are given, but the context alone provides sufficient guidance.

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