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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds meaningful context by promising a 'conservative compliant' path 'without weakening security controls', signalling the advisory, non-mutating nature of the output. It stops short of describing the actual returned structure or any limits/caveats of the classification.

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, front-loaded sentence with no filler, and the core action and output lead the text. However, the brevity is close to under-specification for a tool with such a rich input schema, so it is efficient rather than exemplary.

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, so partial explanation of the return value ('conservative compliant integration path') is acceptable, but the description gives no insight into the deeply nested, documentation-free environment object that dominates the input. For a tool of this apparent complexity, the definition is too thin to reliably guide correct invocation.

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 0%, and the description does not explain the 'intent' enum values or any of the roughly 23 nested 'environment' enums. Given that the single nested object carries the entire diagnostic input surface, the description should compensate but instead only alludes generally to 'observed constraints'. This leaves callers guessing at required field semantics.

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 names a specific verb pair (classify, return) and a clear resource domain (WebMCP, MCP, browser and API constraints), plus a distinct output ('conservative compliant integration path'). An agent can tell this is a diagnostic/advisory tool rather than an executor, though it never explicitly contrasts itself with siblings like kata_plan_triage or kata_run_automation.

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 statement of when to reach for this tool versus the many sibling tools, and no prerequisites or exclusions are given. The phrase 'observed ... constraints' implies the inputs must already be gathered, but that inference is left to the agent. No explicit when-to-use guidance is present.

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