run_wafw00f

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

No annotations are provided, so the description must disclose behavioral traits. It does not mention that the tool sends HTTP requests, may be blocked, or any consequences. This is insufficient for an agent to understand the tool's side effects.

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 that conveys the essential purpose without any unnecessary words. It is perfectly concise.

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 tool with one parameter and no output schema or annotations, the description is minimally adequate. However, it lacks details about output format, prerequisites, or limitations, leaving gaps for the agent.

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 input schema has one parameter with a description ('URL or host to fingerprint.'). The tool description adds no additional meaning beyond the schema, and schema coverage is 100%. Baseline 3 is appropriate.

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 'Fingerprint' and the resource 'web application firewall / security solution in front of a target', making the tool's purpose immediately understandable. It distinguishes from sibling tools like run_nmap or run_curl by specifying WAF fingerprinting.

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 usage for identifying WAFs but provides no explicit when-to-use, when-not-to-use, or alternatives among sibling tools. The context of siblings (e.g., run_nmap, run_curl) suggests this is for after initial reconnaissance, but no guidance is given.

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