MCP cldkctl Server

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

With no annotations provided, the description carries full burden for behavioral disclosure but provides none. It doesn't indicate this is a destructive operation (deleting a PVC), doesn't mention permissions required, doesn't warn about data loss implications, and doesn't describe what happens after deletion. For a deletion tool with zero annotation coverage, this is dangerously inadequate.

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 with a single sentence, the description is under-specified rather than efficiently concise. It wastes its limited space on a tautological statement instead of providing meaningful information. The structure doesn't front-load important information about the tool's purpose or behavior.

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 destructive deletion tool with 3 parameters, no annotations, and no output schema, the description is completely inadequate. It should explain the destructive nature, consequences of PVC deletion, required permissions, and relationship to other resources. The current description fails to provide the minimal context needed for safe and correct usage.

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 description coverage is 100%, so the schema already documents all three parameters (project_id, namespace, name) with basic descriptions. The description adds no additional parameter information beyond what's in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.

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_delete_pvc endpoint' is a tautology that restates the tool name with minimal added meaning. It does specify the action 'call' and the endpoint name, but fails to explain what 'delete_pvc' actually does (deleting a PersistentVolumeClaim in Kubernetes). While it distinguishes from siblings by naming the specific endpoint, it lacks a clear verb+resource explanation.

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 including cldkctl_delete_pod, cldkctl_delete_deployment, and other deletion tools, there's no indication of when PVC deletion is appropriate versus other resource deletions. No prerequisites, warnings, or alternative suggestions are mentioned.

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