MCP cldkctl Server

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

With no annotations provided, the description carries the full burden of behavioral disclosure but offers none. It doesn't indicate whether this is a read or write operation, what permissions are required, whether it's safe to call, what format the response takes, or any rate limits. The generic 'call' provides no behavioral context beyond what's implied by the 'get_' prefix.

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 (5 words) but under-specified rather than efficiently informative. While it doesn't waste words, it also fails to provide essential information that would help an agent understand and use the tool effectively. The single sentence structure is simple but lacks 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?

For a tool with no annotations, no output schema, and a minimal description, this is inadequate. While the zero parameters reduce complexity, the description fails to explain what the tool returns, what Kubernetes resources it interacts with, or any behavioral characteristics. The agent would need to guess based on the name pattern alone, which is insufficient for reliable tool selection.

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 tool has zero parameters with 100% schema description coverage, so no parameter documentation is needed. The description doesn't add parameter information, which is appropriate given the empty input schema. A baseline of 4 is appropriate for a zero-parameter tool where the schema fully covers the parameter space.

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_get_pvc endpoint' is a tautology that restates the tool name without explaining what it actually does. While 'get_pvc' suggests retrieving Persistent Volume Claims, the description fails to specify what resource is being accessed or what operation is performed beyond the generic 'call' verb. It doesn't distinguish this tool from other 'get_' siblings like cldkctl_get_pod or cldkctl_get_deployment.

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. It doesn't mention any prerequisites, context requirements, or differences from similar tools like cldkctl_get_persistent_volume or cldkctl_get_resource_v1. The agent receives no help in determining appropriate usage scenarios.

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