MCP cldkctl Server

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states it 'calls the endpoint,' which implies a mutation (creation) but doesn't disclose critical behavioral traits: what permissions are required, whether it's idempotent, what happens on failure, if it returns the created resource, or any rate limits. For a creation tool with zero annotation coverage, this is a significant gap in transparency.

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 just one sentence, 'Call the cldkctl_create_statefulset endpoint,' which is front-loaded but under-specified. While it wastes no words, it fails to convey necessary information, making it more of an under-specification issue than effective conciseness. It earns a 4 for brevity but loses points for lacking substance.

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 complexity of creating a Kubernetes StatefulSet, no annotations, no output schema, and a nested object parameter, the description is incomplete. It doesn't explain the resource being created, expected inputs beyond the schema, behavioral outcomes, or how it differs from sibling tools. For a mutation tool in a rich Kubernetes management context, this description is inadequate and leaves critical gaps for the agent.

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 has 100% description coverage, with the single parameter 'statefulset_data' described as 'StatefulSet data.' The description adds no additional parameter semantics beyond this. Since schema coverage is high, the baseline score is 3, as the schema does the heavy lifting, but the description doesn't compensate with extra details like format examples or constraints.

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 'Call the cldkctl_create_statefulset endpoint' is a tautology that restates the tool name without explaining what it does. It mentions 'create_statefulset' but doesn't specify what a StatefulSet is (a Kubernetes resource) or what the tool actually creates. While it hints at creation, it lacks the specific verb+resource clarity needed to distinguish it from sibling tools like cldkctl_create_deployment or cldkctl_create_pod.

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 provides no guidance on when to use this tool versus alternatives. With many sibling tools for creating different Kubernetes resources (e.g., cldkctl_create_deployment, cldkctl_create_pod, cldkctl_create_service), there's no indication of when a StatefulSet is appropriate versus other resource types. It doesn't mention prerequisites, context, or exclusions, leaving the agent with no usage direction.

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