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 does disclose useful behavioral traits like pay-per-use, cost in USDC on Base, and severity-based output ordering. However, it does not describe the response shape, processing behavior, or data-handling implications of sending code to the service.

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 compact and front-loaded with the main purpose and pricing. The 'PREMIUM' tag and bracketed payment details are slightly noisy, but nearly every token adds useful information for selection and invocation.

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 simple single-string input tool, the description conveys the core purpose and input type. However, there is no output schema, so the description should more explicitly state what the tool returns; 'by severity' only hints at the result structure. It is adequate but has clear gaps.

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?

The schema only describes the parameter as 'service input', which is generic. The description adds meaningful semantics with 'input=code', telling the agent what kind of content to supply. It does not specify language or format, but it substantially clarifies the otherwise vague parameter.

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 states a specific verb and resource: a security-focused code review, with output organized by severity. The 'security-focused' qualifier distinguishes it from the closely related sibling code-review tool, so an agent can select it without opening the schema.

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?

Usage context is implied: choose this tool when a security-oriented code review is needed. However, there is no explicit when-to-use or when-not-to-use guidance, and the sibling code-review tool is not mentioned as an alternative.

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