B3.2/5.0

Behavior2/5

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

Annotations are empty, so the description carries the full burden of behavioral disclosure. It only states the action and does not mention potential downtime, whether the upgrade triggers a rolling restart, if it is a long-running operation, or any required permissions. This is insufficient for a mutating operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, succinct sentence that directly states the tool's purpose with no unnecessary words. It is appropriately sized and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a complex mutation operation with no annotations and no output schema, the description is too minimal. It omits critical context such as preconditions (precheck), monitoring via upgrade_status, and what the response or result might be. The presence of sibling tools for precheck and status makes this gap more significant.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with descriptions for all three parameters, so the description adds little beyond the schema. The phrase 'Kafka version' is already captured by the 'kafkaVersionCode' parameter description. Therefore, the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Upgrade Kafka version for a CDSS cluster' uses a specific verb (upgrade) and resource (Kafka version for a CDSS cluster), clearly differentiating it from sibling tools like ncloud_cdss_upgrade_precheck and ncloud_cdss_upgrade_status. It unambiguously states the tool's core function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites such as running ncloud_cdss_upgrade_precheck first, nor does it point to ncloud_cdss_upgrade_status for monitoring progress. The description implies the action but lacks explicit usage context.

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