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

No annotations are provided, so the description carries the full burden. 'No identifiers are retained' adds some useful data-handling context, but the description says nothing about side effects, whether this is read-only, authentication needs, or what happens with the inputs. This is minimal disclosure for a tool with zero annotation coverage.

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 only two sentences long, with no filler or repetition, and it leads with the intended purpose. However, the phrasing 'this request' is vague, which slightly reduces the structural value of the front-loaded sentence.

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 four optional parameters, no output schema, and no annotations, an agent has very little to work from. The description does not explain what compatibility means, how the parameters combine, what output to expect, or when this tool is appropriate compared to its many siblings.

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 already have individual descriptions. The tool description adds no parameter-specific meaning beyond the schema, but the baseline of 3 applies because the schema already documents semantics adequately.

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 uses the verb 'Show' and mentions classification, but it never identifies what is being classified: 'this request' is ambiguous and no resource is named. It also does not distinguish the tool from siblings such as compat-sse, normalize-url, or validate-json.

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. The privacy hint 'No identifiers are retained' implies a use case, but the description does not state conditions, exclusions, or relationships to the sibling tools.

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