Behavior2/5

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

Annotations indicate idempotentHint=true and destructiveHint=false, but the description adds no behavioral detail beyond what the annotations provide. It does not mention side effects like cluster restart, rollout behavior, or whether existing configurations are overwritten, which is critical for a config-application action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no fluff. It is concise and readable, though it could have used the space to include a bit more semantic detail without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a configuration operation that may have operational consequences, the description is too sparse. It lacks context about what applying a config group does (e.g., triggers rolling restart), any prerequisites, or expected results. With no output schema, the agent is left without important information for successful invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema provides 100% description coverage for both parameters (configGroupNo and serviceGroupInstanceNo), each with clear descriptions. The tool description adds no additional parameter context, but the schema already fully documents them, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Apply a Config Group to a CDSS cluster' uses a clear verb and resource, and is distinct from sibling tools like create_config_group or delete_config_group. However, it lacks specificity about what 'apply' entails (e.g., activate, propagate) and could be slightly clearer about the scope of the operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives, such as ncloud_cdss_change_kafka_config or ncloud_cdss_create_config_group. The description only states the action without indicating prerequisites, conditions, or exclusions.

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