cluster_create

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

No annotations are provided, so the description must carry the full burden. It only states 'Create a new cluster' without disclosing behavioral traits like side effects, permissions required, or what happens if the cluster already exists. This leaves significant gaps in understanding the tool's behavior.

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 sentence, 'Create a new cluster,' which is concise and front-loaded. While it wastes no words, it could benefit from slight expansion to improve completeness without sacrificing brevity.

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 of nested objects in the input schema and the absence of an output schema, the description is severely incomplete. It fails to explain the structure of the body parameter, what providerSettings expects, or the return value, leaving agents unsupported for correct invocation.

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 input schema has 100% description coverage for top-level parameters but nested properties (name, clusterType, providerSettings) lack descriptions. The tool description adds no parameter information beyond the schema, failing to clarify the meaning or format of nested fields.

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 'Create a new cluster' uses a specific verb and resource, clearly indicating a creation operation. It distinguishes from sibling tools like cluster_get, cluster_update, and cluster_delete by focusing on creation, leaving no ambiguity about the action.

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. There is no mention of prerequisites, conditions, or context that would help an agent decide to invoke this tool over others.

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