k8s_update_kubernetes_cluster

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

With no annotations, the description carries the full behavioral burden. It discloses smart identifier resolution, mentions a change-notification context, and states that it returns an update status message. However, it does not explain the mutation impact, prerequisites, or what happens to unspecified configuration settings.

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 compact and well-structured: a one-line summary, an identifier-resolution note, and an Args/Returns block. It avoids excessive filler, though the out-of-schema ctx entry could be removed to make it tighter.

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 two-parameter update, the description is mostly complete: it covers both schema parameters, explains identifier resolution, and points to a status message while the output schema can carry return details. The main gaps are the lack of usage context relative to sibling update/upgrade tools and the confusing ctx parameter that is not part of the schema.

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%, and the description does add meaning: cluster_identifier is a label or UUID, and label is the new cluster label. On the other hand, it documents 'ctx' as an argument even though it is absent from the input schema, and it omits the nullable/default behavior of label, creating some invocation ambiguity.

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 names a specific verb and resource: 'Update a Kubernetes cluster configuration,' which distinguishes it from node-pool and upgrade siblings at a basic level. The 'Smart identifier resolution' note adds useful context about how the cluster is targeted. However, 'configuration' is somewhat vague, and the description does not explicitly differentiate it from k8s_upgrade_kubernetes_cluster or k8s_update_kubernetes_node_pool.

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 when-to-use versus alternative tools is provided, and no sibling tools are named. The only guidance, 'Smart identifier resolution,' explains how to identify the cluster, not when this update operation should be chosen over related operations like upgrading the cluster or updating a node pool.

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