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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds valuable cost and payment context: $0.25 USDC on Base via x402. But it does not explain what 'bounded' means, whether the audit is rate-limited, or what happens after payment, so it adds only moderate behavioral context.

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?

Two short sentences, front-loaded with purpose and followed by the essential commercial constraint. No words are wasted, and the paid nature is surfaced immediately.

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?

There is no output schema, so the description should explain what an audit returns, but it only says 'audit' without listing outputs. Combined with the unexplained 'request' parameter and absent usage guidance, the definition is too thin for a paid openWorld tool.

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 0%, so the description must carry the burden. It implies the 'text' parameter is the supplied technical text, but it says nothing about the 'request' parameter, its purpose, or any formatting constraints beyond the schema's maxLength.

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 and resource: 'Bounded deterministic audit of supplied technical text.' An agent can tell it audits text rather than blockchain data. However, it does not differentiate from sibling audit_x402_payability, nor does it clarify what 'bounded deterministic' means in practice.

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 when-to-use, when-not-to-use, or alternative tool guidance. It does not mention audit_x402_payability or any other sibling, leaving the agent to infer when this audit is appropriate versus a narrower one.

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