ncloud_cdss_create_config_group

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

The only annotation is destructiveHint: false, and the description ('Create') is consistent with it—no contradiction. However, the description adds no behavioral detail beyond the verb itself: nothing about synchronous vs. asynchronous completion, duplicate-name behavior, or whether the created group needs to be applied to clusters afterward. For a write operation with minimal annotation coverage, this is a partial but not severe gap.

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?

A single front-loaded sentence with zero filler words—'Create a new Config Group for CDSS cluster configuration.' It is efficient for a simple creation operation whose parameters are fully documented in the schema. It is slightly under-sized on context, but not for lack of economy.

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?

The tool is low-complexity (3 flat params, no output schema), and the schema alone is sufficient for a correct basic invocation. What is missing is lifecycle context: that a config group is a template meant to be applied via ncloud_cdss_apply_config_group or referenced at cluster creation, and how this differs from editing via ncloud_cdss_set_config_group_description. Adequate to call, but an agent gets no sense of where this step fits in the CDSS workflow.

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%, so the schema fully documents all three parameters including name format rules and length constraints. The description itself adds no parameter information, which is acceptable at the baseline given the schema does the heavy lifting. The kafkaVersionCode schema hint pointing to ncloud_cdss_get_kafka_versions is a useful provenance cue.

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 (Create), a specific resource (Config Group), and a scope (CDSS cluster configuration) in one clear sentence. It does not explicitly distinguish itself from the similarly-named sibling ncloud_create_cache_config_group, but the 'CDSS' scoping plus the tool-name prefix carry that differentiation.

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 given on when to use this tool versus related CDSS siblings such as ncloud_cdss_apply_config_group (applying a group to a cluster), ncloud_cdss_set_config_group_description (modifying later), or ncloud_cdss_list_config_groups (checking existence). The only contextual hint—that kafkaVersionCode comes from ncloud_cdss_get_kafka_versions—lives in the schema, not the description. No when-to-use, exclusions, or alternatives are mentioned.

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