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 fails to indicate that this is a mutation operation (creating labels), what permissions are required, whether it's idempotent, or what happens on success/failure. The description adds no behavioral context beyond the implied 'create' action.

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, redundant sentence that doesn't convey useful information. While concise, it's under-specified rather than efficiently informative, failing to front-load key details about the tool's purpose or usage.

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 mutation tool with 5 parameters, no annotations, and no output schema, the description is completely inadequate. It doesn't explain what the tool does, when to use it, behavioral implications, or expected outcomes, leaving critical gaps for agent understanding.

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 parameters are documented in the schema. The description adds no additional meaning about parameters (e.g., explaining what 'labels_data' should contain or how IDs relate). This meets the baseline score of 3 since the schema handles parameter documentation 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_registry_labels_create endpoint' is a tautology that merely restates the tool name without explaining what it does. It doesn't specify the action (create labels on a registry), the resource affected, or how it differs from sibling tools like cldkctl_registry_labels_update or cldkctl_registry_labels_delete.

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. The description doesn't mention prerequisites, appropriate contexts, or comparisons to sibling tools (e.g., cldkctl_registry_labels_update for modifying labels or cldkctl_registry_labels for viewing them), leaving the agent with no usage direction.

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