create_users_register

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

No annotations exist, so the description carries the full burden. It fails to disclose behavioral traits like email verification, password strength requirements, side effects (e.g., sending confirmation email), or whether the user is automatically logged in after registration.

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 of three words, which is extremely concise but misses critical details. It is under-specified rather than efficient.

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 (13 parameters, registration process, security sensitivity) and the presence of an output schema, the description is woefully incomplete. It provides no information about return values, error conditions, or any other contextual cues.

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?

With 0% schema description coverage and no explanation of the 13 parameters (5 required), the description adds zero value beyond the schema. Essential fields like email, password, passwordConfirm, and optional fields (group, locale, etc.) are not described.

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 'Register New User' conveys the basic action and resource but is too brief to distinguish from sibling tools like create_admin_users, which also registers a user. It lacks context about self-registration versus admin-initiated registration.

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 provided on when to use this tool versus alternatives (e.g., create_admin_users for admin-created users, create_users_forgot_password for password resets). No context on prerequisites or typical use cases.

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