create_role

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

No annotations are provided, so the description carries full burden. It discloses no behavioral traits such as side effects, permissions, idempotency, or rate limits. The minimal description fails to inform the agent about what happens when the tool is invoked.

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 extremely short (two words) and lacks necessary information. Conciseness should not come at the expense of usefulness; here the description is under-specified and does not earn its place by providing value.

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 absence of annotations and output schema, and the complexity of the input (array with nested required fields), the description is insufficient. It provides no context about return values, error conditions, or using the tool effectively.

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?

Although schema coverage is 100%, the nested properties 'name' and 'description' have no descriptions, and the top-level 'body' description is only a technical HTTP reference. The tool description adds no additional meaning to the parameters, leaving the agent without guidance on what values are expected.

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 role instance' is essentially a restatement of the tool name, providing little additional context. It does not differentiate this tool from siblings like 'clone_role' or 'update_role', nor does it mention that it can create multiple roles via an array input.

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?

There is no guidance on when to use this tool versus alternatives such as 'clone_role' or 'update_role'. No context is provided about prerequisites, use cases, or scenarios where 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.
