ncloud_nks_update_node_pool_label

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

The description adds the critical behavioral detail that the tool performs a PUT that replaces all labels, which goes beyond the idempotentHint and destructiveHint annotations. This helps the agent understand the replace semantics, but it does not mention permissions, side effects, or response details.

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 sentence with a parenthetical note, extremely concise with no unnecessary words. It is front-loaded with the key action and resource.

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 description is adequate for a simple mutation but lacks completeness. It does not mention prerequisites, error conditions, or return values. The lack of an output schema increases the need for such information, which is absent.

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 has 100% description coverage, so the schema already explains the parameters. The description does not add any additional meaning beyond what is in the schema, meeting 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 action (Update), the resource (labels on a node pool in an NKS cluster), and specifies the HTTP method (PUT) which indicates it replaces all labels. This distinguishes it from sibling tools like ncloud_nks_update_node_pool and ncloud_nks_update_node_pool_taint.

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 the tool is for updating labels but provides no explicit guidance on when to use it versus alternatives or when not to use it. The context from sibling tool names suggests differentiation, but the description does not articulate it.

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