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 mentions that no identifiers are retained, which is a privacy note, but it doesn't disclose whether the tool makes network calls, what side effects exist, or what the 'classification' output looks like. The description is incomplete for a tool with 9 parameters.

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 (one sentence), but it is not front-loaded with essential information. It fails to communicate the tool's purpose clearly, so its brevity is a liability rather than an asset. It omits critical context that an agent needs.

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?

With 9 parameters and no output schema, the description is grossly incomplete. It doesn't explain what the classification output looks like, how to interpret it, or any constraints or prerequisites. The description is inadequate for an agent to use 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 the input schema already documents all parameters. The description does not add any meaning beyond the schema; it doesn't explain how the parameters relate to the classification or provide any syntax or usage hints. Baseline 3 is appropriate when the schema does the heavy lifting.

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 vague purpose: 'Show how this request is classified.' It doesn't specify what classification means, what the tool actually does with the inputs, or how it differs from sibling tools like domain-shape or file-path-ok. It is not a tautology but is ambiguous and lacks a clear verb-resource pairing.

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. The description offers no context for selection, no exclusions, and no hints about which sibling tools might be more appropriate for specific tasks. An agent would have no basis to choose this tool over others.

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