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 only states that 'No identifiers are retained,' which is a privacy hint, but fails to disclose whether the tool makes network calls, mutates state, or what it does with the inputs. For a tool with 9 parameters, this is minimal and insufficient.

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 very short, but it is under-specified rather than concise. The two sentences provide almost no actionable information, making the brevity a liability. Essential details about the tool's purpose and behavior are missing, so the description does not earn its place.

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 tool has 9 optional parameters, no output schema, and no annotations, the description is far from complete. It does not explain what classification means, what the output looks like, how the parameters are used, or any other context needed to invoke the tool correctly.

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 coverage is 100%, so each parameter is already documented with a description. The tool description adds no additional meaning about how the parameters relate to the classification or which parameter to use in which situation. Baseline of 3 is appropriate since the schema carries the burden, but the description does not enhance parameter understanding.

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 says 'Show how this request is classified' but does not specify what 'request' means, what classification entails, or which of the 9 parameters is relevant. It does not distinguish the tool from siblings like browser-url-ok or fetch-status, leaving the agent without a clear idea of what the tool actually does.

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 the many sibling tools. The description offers no context about typical use cases, conditions, or exclusions, leaving the agent to guess when this tool is appropriate.

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