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-only operation (though 'get' in the name suggests it), what permissions might be required, whether it returns a single service or a list, what format the response takes, or any error conditions. The description is completely silent on all behavioral aspects beyond the bare action of calling an endpoint.

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?

While technically concise (one sentence), this is a case of under-specification rather than effective conciseness. The single sentence 'Call the cldkctl_get_service endpoint' wastes its opportunity to convey meaningful information. True conciseness would efficiently communicate purpose and usage, but this description is merely minimal without being informative - it doesn't earn its place as a helpful description.

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 description that provides almost no information, this is completely inadequate. The agent needs to understand what 'get_service' means in this Kubernetes/cloud context, what it returns, when to use it, and how it differs from numerous sibling tools. The description fails to provide any of this essential context, leaving the agent with only the tool name to guess its function.

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 0 parameters with 100% schema description coverage, so the schema fully documents the parameter situation (none needed). The description doesn't need to compensate for any parameter gaps. While it doesn't add any parameter information beyond what the schema provides, the baseline for 0 parameters with full schema coverage is appropriately set at 4, as there are no parameters requiring semantic explanation.

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_service endpoint' is tautological - it essentially restates the tool name with 'call' as a generic verb. It doesn't specify what 'get_service' actually does (retrieve service information, list services, etc.) or what resource it operates on. While the name suggests a read operation, the description adds no meaningful clarification beyond the name itself.

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 absolutely no guidance on when to use this tool versus alternatives. Given the extensive list of sibling tools (including other 'get' operations like cldkctl_get_pod, cldkctl_get_deployment, etc.), the agent has no indication of what specific Kubernetes service information this tool retrieves or when it should be preferred over other tools. There's no mention of prerequisites, context, or alternatives.

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