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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It adds one meaningful fact—'No identifiers are retained'—but omits whether the tool performs network requests, has side effects, or returns a classification label, confidence, or status.

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?

Two short sentences with zero filler. The core purpose is front-loaded and the privacy note is a valuable addition that does not waste tokens.

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 description is too thin for a tool with no annotations and no output schema. It fails to explain what 'classified' means, which of the four optional parameters drive the classification, and what the agent can expect back. An agent would struggle to use this tool correctly without more context.

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 100%, so all four parameters are already documented in the schema. The description adds no parameter-specific meaning—'this request' is a generic reference that does not map to url, host, json, or zone.

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 clear verb and resource: 'Show how this request is classified.' It conveys the tool's core function without being a tautology. However, it does not differentiate from siblings like citation or validate-json, and the meaning of 'classified' (compatibility vs. other categories) is left somewhat open.

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 about when to use this tool versus alternatives. No conditions, exclusions, or sibling comparisons are provided; the description only states what the tool does, not when an agent should reach for it.

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