ncloud_cdss_upgrade_precheck

Checks cluster configuration and prerequisites before upgrading Kafka version, preventing upgrade failures by detecting issues early.

C2.3/5.0

Behavior1/5

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

Annotations are empty, so the description carries full responsibility for behavioral disclosure. It only says 'pre-check' without explaining what is validated, whether it is read-only, any required permissions, or how results are returned.

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

Conciseness3/5

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

The description is a single short sentence, making it concise. However, it is under-specification rather than effectively informative, as it provides minimal detail beyond the tool name.

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?

With no output schema and no behavioral details, the description is incomplete for a 3-parameter tool. It does not explain what the pre-check returns, what a successful check looks like, or how it relates to the upgrade workflow.

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?

Schema coverage is 100% (all three parameters have descriptions in the schema). The description adds no extra parameter context, so the baseline of 3 applies.

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

Purpose3/5

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

The description states the tool performs a pre-check before upgrading Kafka version, which is a clear verb+resource. However, it is vague about what the pre-check involves and does not distinguish from related precheck tools like ncloud_cdss_rolling_restart_precheck.

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 about when to use this tool versus alternatives. It does not mention that it should be run before ncloud_cdss_upgrade_version, nor any exclusions or prerequisites.

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