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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, carrying the safety profile. The description adds useful context by characterizing the trail as tamper-evident and scoping it to past guardrail decisions, which hints at what verification entails. No contradiction with annotations, but little added beyond the annotations' coverage.

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 sentence with zero filler. The verb and core object are front-loaded, and every word earns its place by clarifying the scope (wallet's past guardrail decisions).

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 read-only verification tool with a full output schema, the definition is nearly complete: annotations cover the safety profile, the schema documents the parameters, and the description conveys the tool's purpose and scope. A minor gap is the absence of any guidance on what a failed verification implies, but nothing essential to invoking the tool is missing.

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%, so the schema fully documents both parameters (wallet format and limit with its 1-1000 range and default). The description adds no parameter-level meaning beyond the schema, matching the baseline of 3.

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?

States a specific verb (Verify), a specific resource (tamper-evident audit trail), and a precise scope (a wallet's past guardrail decisions). The purpose is unambiguous and easily distinguishable from siblings like check_token_safety and evaluate_trade, which operate on different data entirely.

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 gives no explicit when-to-use or when-not-to-use guidance and names no alternatives. However, usage is reasonably implied by the domain — an agent needing to confirm the integrity of a wallet's guardrail history can infer this is the right tool, and none of the four siblings overlap with audit verification.

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