ncloud_cdss_restart_kafka

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

Annotations already declare idempotentHint=true and destructiveHint=false. The description adds minimal context by naming Kafka and ZooKeeper, but does not disclose operational details like network impact, downtime, or whether the restart is rolling vs. full. This is acceptable given the annotations, but not rich.

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, focused sentence with no redundancy. It front-loads the action and resource, communicating the essential behavior efficiently.

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 restart operation with one parameter and no output schema, the description provides the core purpose clearly. It could have added that this restarts all nodes in the cluster (distinguishing from per_node), but the description is adequate for the tool's simplicity.

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 coverage is 100% and the single parameter serviceGroupInstanceNo has a clear description ('Cluster instance number'). The tool description does not add any additional meaning to the parameter, matching the baseline expectation.

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 verb ('Restart') and the resource ('Kafka and ZooKeeper services in a CDSS cluster'). It distinguishes from sibling tools like restart_kafka_per_node and restart_all_services by specifying the exact services involved.

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 such as ncloud_cdss_restart_kafka_per_node or ncloud_cdss_rolling_restart. The description lacks any 'when to use' or 'instead of' context.

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