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 states only 'detection,' which implies a read-only operation, but gives no detail on what queries are made, what output format to expect, or any side effects or limitations. The bare phrase does not meaningfully disclose behavior beyond the tool's apparent purpose.

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 compact single phrase with no filler or redundant wording. It is front-loaded and remains readable, but the conciseness comes at the expense of important operational details. It earns a high score for brevity, though not for completeness.

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?

Given the large sibling list and the single unannotated parameter, the description is too minimal to fully equip an agent for correct invocation. It lacks input semantics, usage guidance, and behavioral context. The presence of an output schema is acknowledged but not described, so the agent still has unanswered questions.

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 description coverage is 0% – the single parameter `q` has no schema-level documentation. The tool description never mentions `q`, so it adds no meaning to the parameter. An agent cannot determine that `q` should be a domain, URL, or other target value from this text.

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 reasonably specific purpose: 'Tech Fingerprint: CMS/framework/server detection.' This conveys a clear verb ('detection') and resource scope (CMS, framework, server), so an agent understands what the tool does. However, it does not distinguish this from similar siblings like infra_fingerprint or waf.

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 provides no guidance on when to use this tool versus alternatives. It does not mention what input is expected, what context is appropriate for 'tech' vs other fingerprinting tools, or any exclusions. The agent is left to infer usage solely from the tool's purpose.

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