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

With no annotations, the description carries the full behavioral burden. It usefully discloses the pricing/x402 behavior, but not whether classification mutates state, what happens on a non-HTTP surface, what auth is needed, or what the verdict looks like – all critical for a tool whose name implies producing a judgment on a record.

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?

It is a single short sentence with no filler, which is good, but the emphasis is misplaced: pricing occupies the only explanatory slot while the functional contract is left implicit. Shortness here reflects under-specification rather than tightness.

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?

A nested-object input with no schema descriptions, no annotations, and no output schema demands a much fuller description. Missing are the verdict classes, the record's expected structure, and the response format – an agent could not reliably call or interpret this tool from the definition alone.

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?

There is one required parameter, 'record', a nested object with 0% schema description coverage, and the description says nothing about its shape or required fields. Given the nested object, the description should compensate but does not; it only restates the parameter name.

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?

States the verb 'classify' and the resource 'an incident record', which does separate it from the read-only siblings get_flags and get_registry. However, it never says what a verdict is, what classes exist, or what the tool returns, so the purpose is only half specified.

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?

The parenthetical gives billing conditions (first verdict free per operator, then $0.49) but no guidance on when to call this versus get_flags or get_registry, no prerequisites, and no exclusions. An agent learns nothing about tool selection.

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