ncloud_ses_precheck_upgrade

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

No annotations are provided, so the description must convey behavioral traits. It only says 'Pre-check before upgrading', which suggests a read-only validation, but it does not detail what checks are performed, whether it modifies anything, or what the response contains. More behavioral context is needed.

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 extremely concise at 5 words, front-loaded with the key action. While not verbose, it sacrifices detail for brevity. A few more words could improve completeness without harming conciseness.

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 pre-check tool with no output schema, the description should explain what the pre-check does, what success/failure looks like, and how to interpret results. The current description is too sparse to fully guide an agent, especially compared to the richness of sibling tools.

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 already describes both parameters (serviceGroupInstanceNo as 'Cluster instance number' and searchEngineVersionCode as 'Target version code'), achieving 100% coverage. The description adds no additional meaning beyond listing the parameters in the context of upgrade. Therefore, the baseline score 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 clearly states the tool's function ('Pre-check before upgrading Search Engine version') with a specific verb ('Pre-check') and resource ('Search Engine version'). It distinguishes from sibling tools like ncloud_ses_upgrade_version and ncloud_ses_get_upgrade_progress, making it evident when to use this tool.

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 usage via 'before upgrading' but does not explicitly state that this is a prerequisite for the upgrade tool. No alternatives or when-not-to-use guidance is provided. The context from sibling names partially clarifies, but the description itself lacks explicit guidelines.

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