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

With no annotations at all, the description carries the full burden of behavioral disclosure, but it only communicates intent, not behavior. It does not say whether the tool fetches a URL, whether it is a read-only scan, whether it follows redirects, or whether it requires network access. It is not misleading, but it is thin.

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 short, front-loaded, and free of filler; the parenthetical examples and em-dash framing are efficient. It sacrifices explanatory depth, but as a compact phrasing it is well-structured.

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 is a single optional parameter with no annotations and no output contract explained in the description. The output schema may help with return values, but the missing meaning of q is a significant gap that leaves the tool under-specified for reliable invocation.

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 has one parameter, q, with no description and 0% schema description coverage, so the description must explain it. The description never says whether q is a URL, domain, hostname, HTML snippet, or search term, leaving the only input semantically undefined.

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 operation ('enumerate forms/inputs') and gives concrete examples (login/upload) with an attack-surface framing. It clearly conveys what the tool does, though it stops short of 5 because it does not say what target the tool operates on.

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 guidance is given about when to prefer formaudit over siblings such as attack_surface or other web-scanning tools. The attack-surface phrasing weakly implies a security-audit use case, but no explicit context or exclusions are provided.

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