apex_create_user

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

The annotations indicate readOnlyHint=false and destructiveHint=false, but the description adds no additional behavioral context such as side effects, failure modes (e.g., duplicate username), or permission requirements. It merely restates the create operation without enriching what the annotations already provide.

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, front-loaded sentence that directly states the core action. The inclusion of the role list is unnecessary given the schema, making it slightly less concise than ideal, but it remains efficient and well-structured.

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?

Since the input schema is fully described and an output schema exists, the description is not required to explain return values. However, it lacks important context such as the default behavior of workspace_id, how roles are determined, and any preconditions, leaving the overall picture incomplete for a create operation.

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 input schema has 100% coverage for all six parameters, so the description's role mention is the only extra information. However, there is no 'role' parameter in the schema, which could mislead an agent into expecting a role argument. The description fails to clarify how roles are assigned and adds confusion rather than value.

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 uses a specific verb 'Create' and identifies the exact resource 'APEX workspace user', making the tool's purpose unmistakable. It also lists role options to clarify the intent, distinguishing it from siblings like apex_list_users or apex_check_permissions.

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, nor any mention of prerequisites or context such as needing an active workspace or admin permissions. The usage is only implied by the verb 'Create', leaving the agent to infer when it should be invoked.

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