k8s_get_kubernetes_available_upgrades

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

With no annotations, the description carries full behavioral burden. It mentions 'Smart identifier resolution' and the return type, which is useful. However, it does not explicitly state that the operation is read-only, whether authentication is required, or how errors are surfaced. For a simple get, this is adequate but not rich.

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 concise and well-structured with Args/Returns sections. The 'Smart identifier resolution' line is informative, though the Args section repeats what the parameter is. No wasted words.

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 single-parameter read operation with an output schema, the description provides sufficient information: what the tool does, what input is expected, and what is returned. Missing details like error cases or prerequisites are minor given the simplicity and sibling context.

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 provides only a string type with no description (0% coverage). The description adds meaning by specifying 'cluster_identifier: The cluster label or ID' and stating that both label or UUID are accepted. This compensates for the schema gap.

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 tool's purpose: 'Get available Kubernetes version upgrades for a cluster.' It specifies the resource and verb. It distinguishes from sibling tools like k8s_get_kubernetes_versions by scoping to 'upgrades for a cluster', though it doesn't explicitly name alternatives.

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 is given on when to use this tool versus sibling tools such as k8s_get_kubernetes_versions or k8s_upgrade_kubernetes_cluster. The 'Args' section explains the parameter but does not provide selection criteria, prerequisites, or exclusions.

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