k8s_create_kubernetes_node_pool

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

With no annotations, the description carries the burden of behavioral disclosure. It openly states this is a create operation, notes smart identifier resolution, and mentions label uniqueness within the cluster. However, it does not disclose billing implications, quota requirements, prerequisites like an existing cluster, or whether creation is asynchronous.

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 well-organized with a one-line purpose statement followed by an Args section and a Returns note. It is efficient and front-loaded, though including 'ctx' as an argument when it is not in the schema introduces minor noise.

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 9-parameter create operation with no annotations and no schema-level descriptions, the description covers the parameters and return value reasonably. However, it omits useful context such as the prerequisite that the cluster must already exist, how to discover valid plan IDs, and behavioral interactions between auto_scaler and min/max_nodes.

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 0%, so the description must compensate for missing parameter documentation. It does this well by explaining every schema parameter, including cluster identifier resolution, minimum and recommended node quantity, a plan ID example, and label uniqueness. This is substantially richer than the bare input schema.

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 opens with a clear, specific verb and resource: 'Create a new node pool in a Kubernetes cluster.' This distinguishes it from sibling tools like k8s_create_kubernetes_cluster and k8s_scale_kubernetes_node_pool, since the resource being created is unambiguous.

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 gives no explicit guidance about when to use this tool versus alternatives such as k8s_scale_kubernetes_node_pool or k8s_update_kubernetes_node_pool. One can infer that creating a new pool is intended for adding capacity, but the description does not state this or mention exclusions.

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