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 fails completely. It doesn't indicate this is a mutation operation (editing implies changes), what permissions might be required, whether changes are destructive or reversible, what happens to the existing StatefulSet, or what the expected response looks like. For a tool that modifies Kubernetes resources, this lack of behavioral information is critically inadequate.

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 just one sentence, this is a case of harmful under-specification rather than effective brevity. The single sentence 'Call the cldkctl_edit_statefulset endpoint' wastes its opportunity to convey meaningful information, essentially repeating the tool name without adding value. True conciseness would communicate essential information efficiently, not omit it entirely.

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 no annotations, no output schema, and complex parameters (including a nested statefulset_data object), this description is completely inadequate. It doesn't explain what 'edit' entails, what format statefulset_data should be in, what happens on success/failure, or how this differs from create/delete operations. Given the Kubernetes context and sibling tools, this leaves critical gaps in understanding the tool's purpose and behavior.

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 all four parameters clearly documented in the schema itself (project_id, namespace, name, statefulset_data). The description adds zero additional information about parameter meaning, relationships, or usage. Since the schema does all the heavy lifting, the baseline score of 3 is appropriate - the description neither helps nor harms parameter understanding.

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_edit_statefulset endpoint' is a tautology that merely restates the tool name with minimal action. It doesn't specify what 'edit' means operationally (e.g., update, patch, modify), what resource is being edited (a Kubernetes StatefulSet), or how it differs from sibling tools like cldkctl_create_statefulset or cldkctl_get_statefulset. This provides almost no useful information beyond the name itself.

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 on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., existing StatefulSet), when editing is appropriate versus creating/deleting, or how it relates to sibling tools like cldkctl_edit_deployment or cldkctl_edit_pod. An agent would have no contextual clues about appropriate usage scenarios.

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