ncloud_nks_upgrade_node_pool

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

Annotations are empty, so the description must disclose behaviors, but it only mentions 'Uses PATCH with query parameters' which is irrelevant for the agent. It does not describe side effects (e.g., rolling update, downtime) or what happens to workloads.

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 very concise (two sentences, 16 words) with the main purpose front-loaded. The second sentence about HTTP method is slightly unnecessary but doesn't harm conciseness significantly.

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 significant operation like upgrading a node pool, the description lacks context on expected outcomes, status returns, prerequisites (e.g., cluster must exist), and effects on running pods. No output schema exists to compensate.

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 schema provides 100% coverage with descriptions for all parameters, so the description adds no extra meaning. Baseline of 3 is appropriate.

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 'Upgrade the Kubernetes version of a node pool,' which is a specific verb and resource. It distinguishes from sibling tools like ncloud_nks_upgrade_cluster (upgrades entire cluster) and ncloud_nks_update_node_pool (updates other properties).

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 on when to use this tool versus alternatives (e.g., ncloud_nks_upgrade_cluster), prerequisites, or when not to use it. The description only states the action without context.

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