list_tkc_clusters

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds value by specifying the return structure (total count and list with status and K8s version) and the filtering behavior (lists all if namespace not specified), which are not captured by 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 concise with a clear front-loaded '[READ]' tag, a single-line purpose, and bullet-style parameter explanations. Every sentence adds value without redundancy.

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 simple list tool with 2 optional parameters and no output schema, the description covers all essential aspects: what it lists, how to filter, and the return format. No critical gaps are evident.

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?

Input schema has 0% description coverage. The description explains the purpose of both parameters: namespace filters by vSphere Namespace (default all), target is the vCenter target. This adds meaning beyond the schema titles, though more detail (e.g., valid values) would be better.

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 verb 'List', the resource 'TanzuKubernetesCluster (TKC) clusters', and the scope (filter by namespace). It distinguishes from sibling tools like 'get_tkc_cluster' (single cluster) by indicating it returns a list.

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 implies usage context (listing clusters, optionally filtered by namespace) but does not explicitly state when to use this tool versus alternatives (e.g., 'get_tkc_cluster'). No 'when not to use' or 'see also' guidance is provided.

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