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

The readOnlyHint annotations already establish this as a safe read operation. The description adds minimal behavioral context beyond stating its purpose and association with cluster creation. It does not describe response format, pagination, or other behavioral details, but given the annotation coverage, a mid-range score is appropriate.

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 a single, clear, front-loaded sentence that conveys the essential information without any filler. It is appropriately concise for a simple, no-parameter retrieval tool.

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?

For a no-parameter, read-only list retrieval tool with good annotations, the description is complete. It states what the tool returns (Kafka version list) and its purpose (CDSS cluster creation), which is sufficient for the agent to select and invoke it correctly.

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?

The tool has zero parameters, and the schema coverage is 100% (empty schema). The description correctly implies no inputs are needed. With no params, the baseline is 4, and the description does not need to compensate for missing parameter information.

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 clearly states the tool's function: retrieving available Kafka version lists specifically for CDSS cluster creation. The verb 'Get' and resource 'Kafka version list' are specific, and the context 'for CDSS cluster creation' distinguishes it from other version-related tools in the sibling set.

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 description implies when to use this tool: when creating a CDSS cluster and needing to select a Kafka version. It provides clear context but does not explicitly mention alternatives or exclusions, which would warrant a 5.

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