create_ranger_user

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'WRITE OPERATION' but does not cover side effects, permissions, idempotency, or error scenarios, leaving significant gaps.

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 very short and to the point, with an emphasized 'WRITE OPERATION' and specific parameter notes. It avoids redundancy but could benefit from a clearer separation of overall purpose vs parameter details.

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 zero schema description coverage, the description should compensate. It partially explains two of six parameters, but lacks completeness on required fields like user_name, password constraints, and return values despite an output schema existing.

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 description adds meaning for user_roles and group_ids (e.g., 'ROLE_USER or ROLE_SYS_ADMIN', 'comma-separated numeric ids'), which the schema lacks. However, it does not explain other parameters like user_name, password, first_name, last_name, so coverage is incomplete.

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 'Create a Ranger user' with a specific verb and resource, distinguishing it from sibling tools like delete_ranger_user or get_ranger_user. The 'WRITE OPERATION' emphasis further clarifies 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?

No explicit guidance on when to use this tool vs alternatives. It only indicates it's a write operation, but does not mention when to avoid it or suggest other tools for similar tasks.

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