ncloud_ses_upgrade_version

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

With empty annotations, the description carries the full burden of disclosing behavioral traits. It does not mention that upgrading is a long-running, potentially destructive operation, nor does it specify any prerequisites, error states, or whether the cluster becomes unavailable during the upgrade.

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 sentence, which is concise. However, it lacks any additional structure or detail that would improve usability. It is front-loaded but too brief to be fully useful.

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 complexity of a version upgrade, the description is incomplete. It does not mention the expected return value, whether the operation is asynchronous, or any side effects. The lack of output schema and behavioral details makes it insufficient for an agent to use correctly without additional 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?

The input schema provides 100% coverage with clear descriptions ('Cluster instance number', 'Target version code'). The description adds 'Search Engine version' but does not significantly enhance understanding beyond what the schema already offers. Baseline of 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 'Upgrade Search Engine version for a cluster' clearly states the action and resource. However, it does not differentiate from related sibling tools like ncloud_ses_precheck_upgrade or ncloud_ses_get_upgrade_progress, which are likely prerequisites or status checks for the same operation.

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 guidance is provided on when to use this tool versus alternatives. For example, it should mention that a precheck should be performed first via ncloud_ses_precheck_upgrade, or that upgrade progress can be monitored via ncloud_ses_get_upgrade_progress. The absence of such context makes it difficult for an agent to decide the proper workflow.

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