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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Detect' and gives no information about input expectations, data sources, limits, or result behavior; it neither contradicts annotations nor meaningfully discloses operational traits.

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, but the opening 'C2 Infrastructure:' repeats the title before restating the purpose. It is concise yet under-specified, and the structure adds no useful detail or emphasis.

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 tool with no annotations and one undocumented parameter, the description is not complete enough for correct invocation. The output schema may define return values, but the input semantics and the tool's place among adjacent C2/threat-intel tools are missing.

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 only parameter, q, has 0% schema description coverage, and the description does not explain what q should contain (e.g., IP, domain, hostname). An agent cannot infer the correct input format from either the schema or the 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 gives a clear verb and resource: 'Detect C2 infrastructure + hosting.' It tells an agent what the tool does at a high level, though it does not differentiate it from related siblings like botnet_tracker or threat_actor.

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?

There is no guidance on when to use this tool versus its many threat-intel siblings, no exclusions, and no prerequisites. The only usage signal is the implicit one in the stated purpose.

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