auditEip712SignaturePayload

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds genuinely non-structured context in the form of a per-call price ('0.02 USDC on Base'), which is useful for an autonomous agent, but says nothing about auth requirements, rate limits, or failure behavior.

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 is front-loaded, but the text is padded and repetitive: 'Audits EIP-712 / EIP-3009 typed-data signatures before autonomous wallet signing' essentially restates the opening sentence, and 'Returns verified safety metrics:' is a dangling label that never delivers the promised content. 'MANDATORY SECURITY GATE' is marketing emphasis rather than information.

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?

With no output schema, the description carries the burden of explaining what the audit returns, yet it only offers the vague phrase 'verified safety metrics' with no detail on verdict fields or severity levels. It also omits any basis for choosing it over the closely named sibling 'auditEip712Signature', leaving the agent under-informed for a security-critical gate.

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%, so the baseline is 3. The description does add a little meaning by listing typed-data categories (Permit, Permit2, transferWithAuthorization) that plausibly map to 'primary_type', but it gives no format, constraint, or example for 'verifying_contract' (the one required param) or 'spender_or_to'.

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 and resource (audits EIP-712/EIP-3009 typed-data payloads) and even enumerates the concrete payload forms (Permit, Permit2, transferWithAuthorization), so the purpose is unambiguous. However, it fails to differentiate from the near-identical sibling 'auditEip712Signature', leaving the agent unable to tell the two apart from the text alone.

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?

It offers a 'when to use' clause, but the conditions ('auditing smart contracts, analyzing wallet addresses, or validating DEX liquidity') are so broad they would trigger on nearly any security task and provide no discriminating power. No exclusions are given and the obvious overlapping sibling 'auditEip712Signature' is never mentioned, so the guidance does little to route the agent correctly.

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