get_tkc_available_versions

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

Annotations already declare readOnlyHint=true, destructiveHint=false, etc. The description adds the read context ([READ]) but no additional behavioral traits like caching, pagination, or version format. No contradiction with annotations.

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 extremely concise with a single-line purpose and a compact arg list. Every sentence provides necessary information with 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?

Given the context of many sibling tools and no output schema, the description could mention the return format or version representation. It's adequate for basic use but misses details that would help an agent fully understand the output.

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 has 0% description coverage, but the description explains both parameters: 'namespace: vSphere Namespace (used to connect to Supervisor)' and 'target: vCenter target name'. This adds meaningful context beyond the bare 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 'List K8s versions available for new TKC clusters', specifying the action (list) and resource (available versions). This distinguishes it from sibling tools like get_tkc_cluster or list_tkc_clusters, and the '[READ]' prefix reinforces read-only intent.

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 explains the parameters but lacks explicit guidance on when to use this tool versus alternatives. While it's implied for pre-creation checks, no exclusions or alternative tools are mentioned.

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