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

The description and parameter hints disclose that identifiers are not retained, values are discarded after checks, and no disk access occurs, which is useful privacy information. However, it does not explain whether network requests are made, what side effects exist, or what the output/return behavior is, leaving major behavioral aspects unspecified.

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 extremely concise: two sentences with no redundant wording. Parameter descriptions are also short and to the point. There is no fluff or unnecessary detail.

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?

Despite the minimal description, the tool has nine optional parameters, no output schema, and no annotations. The description fails to explain what the tool returns, how the classification is determined, how parameters relate to the result, or provide any examples. An agent cannot predict the tool's behavior or output from the given 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?

All nine parameters are documented with meaningful descriptions that go beyond their names: 'Git ref name', 'HTTPS URL to normalize or cite', 'IANA timezone name', etc. The schema coverage is 100% and each description adds context about the expected value and disposal behavior, so this dimension is strong.

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 says 'Show how this request is classified' but never defines what classification means, what categories are produced, or what 'compatibility' refers to. The verb 'show' is generic and the resource/result is left unspecified, making the purpose vague.

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 any of the 26 sibling tools. The description does not mention alternatives, prerequisites, or typical use cases, so an agent gets no help selecting it.

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