cluster_policies_create

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

Annotations already indicate readOnlyHint=false, signaling a write operation. The description confirms this by stating 'create'. However, no additional behavioral traits are disclosed, such as idempotency, required permissions, or side effects. The description adds minimal value beyond annotations.

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 that concisely states the purpose and return value. It is front-loaded but lacks additional structure. Although brief, it earns its place with no wasted words.

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?

With 6 parameters and an output schema, the description could be more complete. It mentions the return value but does not explain how to construct the policy definition, handle policy family inheritance, or potential failure modes. Adequate but not thorough.

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 covers 67% of parameters with descriptions. The tool description adds no extra parameter-level information beyond what the schema provides. For the remaining parameters without schema descriptions, the description does not compensate. Baseline score of 3 is appropriate.

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 clearly states the action 'create a cluster policy' and mentions the return value 'policy_id'. However, it does not differentiate this tool from siblings like cluster_policies_edit or cluster_policies_get, which handle related operations.

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 such as cluster_policies_edit for updating or cluster_policies_delete for deletion. There is no context on prerequisites or 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.
