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 discloses the type of output (issues with reproductions) but does not mention behavioral traits like whether the code is executed, potential risks, or side effects. It provides basic transparency but lacks depth.

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 sentence with clear front-loading of the purpose. It is concise and contains no unnecessary information. Slight improvement could be achieved with bullet points, but it is effective.

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?

The tool has 3 parameters (1 required) and no output schema. The description explains the output format ('severity-ranked issues with reproductions') but lacks details on the return structure or prerequisites. It is adequate for simple use but could be more comprehensive.

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 has 3 parameters with 67% description coverage. The description adds little beyond the schema: it mentions 'code or design' which matches the schema's 'code' description, but does not elaborate on the 'model' parameter or add new semantics. The description does not compensate for the missing parameter description.

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 clearly states the verb 'adversarially break' and the resource 'piece of code', and specifies the output: 'severity-ranked issues with reproductions'. It effectively distinguishes from sibling tools like grok_chat, grok_consult, and grok_review.

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 implies when to use this tool: when you want to find edge cases, race conditions, security holes, or adversarial inputs. It does not explicitly state when not to use or list alternatives, but the differentiation from siblings is clear.

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