MCP cldkctl Server

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

No annotations are provided, so the description must fully disclose behavioral traits. It only states 'Call the endpoint,' which doesn't reveal if this is a mutation (likely, given 'create'), what permissions are needed, if it's idempotent, or what happens on failure. This is inadequate for a tool that likely modifies system state.

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 a single sentence, but it's under-specified rather than concise. It wastes space by restating the tool name without adding value, failing to front-load useful information. A more efficient structure would directly state the tool's purpose.

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 a creation tool with no annotations, no output schema, and a nested object parameter, the description is completely inadequate. It doesn't explain what a PVC is, the expected outcome, error handling, or any behavioral context, leaving the agent with insufficient information to use the tool correctly.

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 schema description coverage is 100%, with the parameter 'pvc_data' documented as 'Persistent Volume Claim data.' The description adds no additional meaning beyond this, so it meets the baseline of 3. However, it doesn't compensate for any gaps, as the schema already covers the single parameter adequately.

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_pvc endpoint' is a tautology that restates the tool name without explaining what it does. While 'create_pvc' suggests creating a Persistent Volume Claim, the description doesn't specify the verb ('create') or the resource ('Persistent Volume Claim') clearly, making it vague. It doesn't distinguish from siblings like 'cldkctl_create_persistent_volume' or 'cldkctl_edit_pvc'.

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 prerequisites, context, or exclusions, such as when to choose this over other creation tools or when PVC creation is appropriate. With many sibling tools for managing resources, this lack of guidance is misleading.

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