MCP cldkctl Server

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. The description reveals nothing about what the tool actually does (read vs write, side effects, permissions needed, rate limits, or output format). 'Call the endpoint' is completely uninformative about behavior, leaving the agent with no understanding of the operation's nature or consequences.

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 brevity. The single sentence 'Call the cldkctl_registry_overview endpoint' wastes its opportunity to convey meaningful information, making it inefficient rather than appropriately concise. It fails to front-load useful information.

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 (multiple registry operations) and the complete lack of annotations and output schema, the description is severely inadequate. It provides no information about what the tool returns, what 'overview' entails, or how it differs from other registry tools. For a tool in what appears to be a container registry management system, this leaves the agent with essentially no usable context.

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% (registry_id is documented as 'Registry ID'), so the baseline is 3. The description adds no additional parameter information beyond what's already in the schema. It doesn't explain what a registry ID is, how to obtain it, or provide any context about valid values or constraints.

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_overview endpoint' is a tautology that merely restates the tool name without explaining what the tool actually does. It doesn't specify what 'overview' means or what resource it operates on, nor does it differentiate from sibling registry tools like cldkctl_registry_detail or cldkctl_registry_list. This provides minimal actionable information to an agent.

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 (e.g., cldkctl_registry_detail, cldkctl_registry_list, cldkctl_registry_repositories), there's no indication of what distinguishes this 'overview' endpoint from other registry-related operations. The agent receives zero contextual usage information.

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