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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains what the tool does but omits side effects, permissions, rate limits, return format, or safety profile. It does not state whether it is read-only, how output is structured, or any constraints such as file size limits. This leaves significant uncertainty for the agent.

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, efficient sentence that front-loads the purpose and includes a parameter hint. It is not bloated, but its brevity sacrifices essential details. Structurally it is acceptable, though it could be better organized with separate lines for purpose and parameter guidance.

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 performs complex file analysis but has no output schema, so the description should explain what the agent can expect in return (e.g., a report, specific fields, error handling). It also does not mention any prerequisites, limits, or authentication requirements beyond the api_key parameter. The description is incomplete for an agent to fully understand the tool's behavior and results.

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%, so the description must compensate for missing parameter documentation. It only clarifies that file bytes are passed as base64 (content_base64), but says nothing about api_key or filename. This is insufficient for an agent to correctly construct all parameters, especially since the schema provides no descriptions.

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 verb ('Inspect') and resource ('a file'), and enumerates the exact analysis types (hashes, entropy, strings, metadata, PE/PDF/Office), making the tool's purpose unambiguous. While it doesn't contrast with siblings, the purpose is clear enough for an agent to distinguish it from other lynx tools.

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 on when to use this tool versus alternatives, nor are there exclusions or conditions. The only instruction is to pass file bytes as base64, which is a parameter hint, not a usage guideline. The agent receives no context for selecting this tool over its siblings.

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