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. It fails to indicate whether this is a read or write operation, what permissions are required, what the output format might be, or any side effects. The description adds no value beyond the tautological statement, leaving the agent completely in the dark about how the tool behaves.

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 the description is brief, it is under-specified rather than concise. The single sentence 'Call the cldkctl_registry_repositories endpoint' wastes its opportunity to convey useful information, making it inefficient. It fails to front-load critical details, offering no operational value to the agent.

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 implied by the sibling tools (e.g., registry management in a cloud/container platform) and the absence of annotations and output schema, the description is completely inadequate. It does not explain the tool's purpose, behavior, or output, leaving the agent unable to use it effectively. This is a significant gap for a tool in a rich ecosystem.

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%, with the single parameter 'registry_id' clearly documented in the schema. The description adds no additional meaning about the parameter, such as where to find the registry ID or format examples. Since the schema does the heavy lifting, the baseline score of 3 is appropriate, though the description contributes nothing.

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_registry_repositories endpoint' is a tautology that restates the tool name without explaining what it does. It lacks a specific verb and resource, failing to distinguish this tool from its many sibling registry tools (e.g., cldkctl_registry_list, cldkctl_registry_detail). The agent cannot determine if this tool lists, creates, modifies, or deletes registry repositories.

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?

No guidance is provided on when to use this tool versus alternatives. With numerous sibling tools like cldkctl_registry_list, cldkctl_registry_repository_list, and cldkctl_registry_detail, the description offers no context, prerequisites, or exclusions. This leaves the agent guessing about the appropriate use case.

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