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

With no annotations, the description carries the full burden, and it discloses only the payment model (5 free calls per signed wallet). It never says what the audit actually examines (vulnerabilities, licenses, dependencies), whether it needs a signed wallet to run, or what happens on a paid call.

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?

Short and front-loaded with no redundant filler, but the brevity reflects under-specification rather than efficient packaging. Two terse sentences for a three-parameter tool leaves far too much unsaid.

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?

No output schema, no annotations, and three undocumented parameters mean the description must do all the work, and it does not. It omits parameter meaning, requiredness handling, and any indication of the audit's output or limitations.

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% across three parameters, and the description adds nothing. It does not clarify the distinction between 'name', 'package', and 'version' (all three present, none required), leaving an agent unable to choose values correctly.

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+resource: 'Python package security audit.' The language qualifier ('Python') implicitly separates it from the sibling x402-npm-audit, but the description never names that alternative explicitly, so it falls short of full sibling differentiation.

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?

No when-to-use guidance, no prerequisites, and no comparison to the many adjacent package/security tools (x402-npm-audit, x402-pypi-package-info, x402-token-security). The '5 free trial calls per signed wallet' line is a pricing note, not usage guidance.

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