ncloud_ses_delete_cluster

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

Annotations already flag destructiveHint=true, but the description adds critical behavioral context: permanent deletion, total data/index loss, and the requirement to set confirm=true for execution. This goes beyond the annotation to disclose consequences and the safety mechanism, with no contradiction.

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?

Three short, front-loaded sentences with a warning icon and 'Destructive' label. Every word earns its place, conveying purpose, consequences, and execution requirement without waste.

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 simple 2-parameter destructive operation with annotations, the description fully covers purpose, consequences, and execution requirement. No output schema exists, and return values are not needed for this tool's complexity.

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% for both parameters (serviceGroupInstanceNo and confirm). The description reiterates the confirm=true requirement but adds no new parameter semantics beyond what the schema already provides, so the baseline of 3 applies.

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 a specific verb+resource: 'Permanently delete a Search Engine Service cluster.' It clearly identifies the resource type (SES cluster) and distinguishes it from sibling delete cluster tools like ncloud_cdss_delete_cluster and ncloud_nks_delete_cluster by naming the service.

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?

Provides clear context: use this tool to permanently delete an SES cluster. The service-specific naming and destructive warning make the usage obvious, though it does not explicitly mention alternatives or state when not to use it.

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