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

With no annotations present, the description carries the full burden and adds exactly one behavioral fact: 'No identifiers are retained,' which is a useful privacy disclosure. It never discloses whether the operation is read-only, has side effects, makes network calls, or what happens when multiple parameters are supplied simultaneously. For an 8-parameter tool with no annotation safety profile, this is thin.

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 the core purpose front-loaded and the privacy note second, containing zero wasted words. It is efficiently structured, though the brevity comes at the cost of specification depth.

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?

There is no output schema and no annotations, yet the description is only two sentences for a tool with 8 heterogeneous parameters and 28 closely related siblings. It omits the response shape, how parameters interact, whether multiple params can be passed, and the classification taxonomy, leaving an agent unable to predict the tool's result.

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 effectively 100% - every parameter has its own description, several noting it is 'discarded after the check' - so the schema carries the semantic load and the baseline is 3. The description adds no parameter-level meaning beyond what the input schema already provides.

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 verb ('Show') and a resource ('this request') and names the output (a classification), so it is not a tautology. However, 'classified' is undefined: the tool accepts 8 unrelated parameter types (ref, url, city, feed, json, path), and the description never explains what categories or labels the classification produces, nor how it relates to the ~28 sibling tools. This reads as vague-purpose rather than clear-but-undifferentiated.

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 call this tool versus siblings such as validate-json, normalize-url, or file-path-ok, even though the parameter names map directly to those tools' domains. The only implied context is 'when you want a classification,' with no exclusions, prerequisites, or named alternatives. This is effectively no usage guidance for a dispatcher-like tool.

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