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 offers none. It doesn't indicate whether this is a read or write operation, what permissions are required, what happens when called, or what the expected behavior is. The description is completely silent on all behavioral aspects.

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 only one sentence, this description is under-specified rather than appropriately concise. The single sentence 'Call the cldkctl_registry_labels endpoint' provides no meaningful information and wastes the opportunity to convey purpose or usage. Conciseness should not come at the expense of basic utility.

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 4 required parameters and no annotations or output schema, the description is completely inadequate. It provides no information about what the tool does, when to use it, what behavior to expect, or what results it returns. For a tool with multiple required identifiers and registry context, this minimal description fails to provide the necessary context for effective use.

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%, so all parameters are documented in the schema. The description adds zero information about parameter meaning, usage, or relationships beyond what's already in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no parameter information 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_registry_labels endpoint' is a tautology that merely restates the tool name without explaining what the tool actually does. It provides no verb-action combination or indication of what resource is being manipulated. Compared to sibling tools like 'cldkctl_registry_labels_create' or 'cldkctl_registry_labels_delete', this description fails to distinguish its purpose.

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 about when to use this tool versus alternatives. There's no mention of context, prerequisites, or comparison to related tools like the various other registry-related tools in the sibling list. An agent would have no idea when this tool is appropriate.

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