create_user

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

With no annotations provided, the description only states it creates a user but does not disclose behavioral traits such as whether it sends invitations, requires admin privileges, or what happens on duplicate email. Basic creation action is noted, but not enough for a full picture.

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?

Two sentences, 18 words, with the primary action in the first sentence and supplementary context in the second. No wasted words, and the structure is front-loaded.

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 has 16 parameters and is a creation action, the description is too brief. It lacks information on return value, error handling, permissions required, or any side effects. The absence of output schema and annotations increases the need for completeness, which is not met.

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%, and the schema clearly defines each parameter. The description adds 'roles and permissions' context but does not enhance understanding beyond the schema. Baseline 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?

Description clearly states the tool creates a new user with roles and permissions, differentiating it from sibling tools like create_client or create_project. The verb 'create' and resource 'user' are specific.

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 versus updating an existing user with update_user, nor any prerequisites or exclusions. The description implies team management but lacks clear usage context.

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