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

No annotations are provided, so the description carries the full burden. It states the tool 'Verif[ies]' but does not disclose whether it modifies state, what happens upon detection, or authentication requirements. The behavioral traits beyond purpose are insufficiently described.

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 description is a single, efficient sentence with a parenthetical cost note. It is front-loaded and contains no superfluous words.

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?

Given no annotations, no output schema, and only one parameter with an external schema link, the description lacks essential behavioral details (e.g., response format, side effects). For a verification tool, more context is needed to be complete.

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% for the single parameter 'input', with the schema describing it as 'Free-form input payload'. The description adds a link to external schema details but no additional meaning beyond the schema. Thus, it meets the baseline for high coverage.

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 uses a clear verb 'Verify' and specifies the resource 'memory/state', along with concrete detection targets ('drift, corruption, unauthorized modifications'). This clearly distinguishes it from sibling tools like 'audit' or 'delphi'.

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 mentions cost and platform ('$0.01 USDC per call on Base, via x402'), providing some context for when to use it, but does not give explicit when-to-use or when-not-to-use guidance nor alternatives.

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