create_user

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

With no annotations, the description carries full burden for behavioral disclosure. It only states the admin privilege requirement. It does not mention side effects (e.g., email sending), success/error behavior, or default values for parameters like status or password generation. Significant gaps exist.

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, clear sentence that conveys the core purpose and a key requirement. It is front-loaded and efficient, though it could be slightly expanded to cover more behavioral context without becoming verbose.

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 tool's complexity (14 parameters, no output schema, no annotations), the description is insufficient. It fails to explain return values, default behaviors, error conditions, or the role of optional parameters like status or send_information. The agent would lack critical context 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?

Schema description coverage is 100%, so the schema already documents all parameters. The description adds no additional meaning or context beyond the tool purpose, thus providing no extra value for parameter semantics.

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 ('Creates') and the resource ('a new user in Redmine'), which distinguishes it from sibling tools like update_user or delete_user. However, it does not explicitly differentiate from other creation tools (e.g., create_project), but the resource is specific enough.

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 mentions 'Requires admin privileges,' which is a prerequisite, but does not provide explicit guidance on when to use this tool versus alternatives (e.g., update_user). The context of sibling names implies differentiation, but no 'when-to-use' or 'when-not-to-use' is stated.

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