ncloud_cdss_upgrade_precheck

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

Annotations are empty, so the description carries full burden. The description says 'Pre-check' but does not disclose whether this is a read-only operation, what side effects it has, or what it validates. No contradictions with annotations, but transparency is minimal.

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 very short (one noun phrase), which is concise but lacks a proper sentence structure. It is not grammatically complete and could be improved with a verb and more detail without adding much length.

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?

Given the tool has 3 parameters, no output schema, and no annotations, the description is too sparse. It does not mention return values, error conditions, or prerequisites. For a pre-check tool, the description should explain what the outcome is (e.g., returns a list of issues or a pass/fail status).

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% (all 3 parameters described in schema). However, the description adds no additional meaning beyond what the schema already provides. It does not explain how parameters like configGroupNo or kafkaVersionCode are used in the pre-check. Baseline 3 is appropriate.

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 states 'Pre-check before upgrading Kafka version', clearly indicating a validation action related to Kafka upgrades. It distinguishes itself from sibling tools like ncloud_cdss_upgrade_version and ncloud_cdss_upgrade_status. However, it lacks specificity on what exactly is checked (e.g., configuration, connectivity, readiness).

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?

No explicit guidance is given on when to use this tool versus alternatives. It is implied it should be used before an upgrade, but there is no 'when to use' or 'when not to use' explanation. Sibling tools exist for upgrade and status, but the description does not clarify that this is a prerequisite step.

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