list_kubernetes_versions

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

With no annotations, the description partially covers behavior by stating ordering and purpose. However, it does not disclose the return format or whether there are any side effects, though it is likely read-only. Could be more explicit.

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?

Two concise sentences with no redundant information. All content is essential.

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?

Given zero parameters and no output schema, the description is largely complete. It specifies the resource, ordering, and usage. Could mention if it returns all versions or only available ones, but 'currently offered' implies availability.

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?

No parameters exist, and schema_description_coverage is 100%. The description adds context about the versions being managed-Kubernetes (Gardener shoot), which is extra value beyond the 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 clearly states it lists managed-Kubernetes versions, specifies the context (Gardener shoot), and mentions ordering (newest-supported first). It is specific and distinguishes from siblings as no other tool lists these versions.

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?

Explicitly states when to use: 'to pick or validate a version before deploying a cloud-k8s cluster.' While no alternatives are provided, the tool is unique among siblings, so no when-not-to-use is needed.

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