users_create

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

The annotation readOnlyHint:false already indicates mutation, and the description's 'Create' aligns. However, no additional behavioral traits are disclosed, such as idempotency, duplicate handling, or permission requirements, which are critical for a mutation tool with no other annotations.

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 concise sentence that front-loads the main purpose. It is efficient but could include more value 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 6 parameters and low schema coverage, the description is too brief. It lacks context on default values, validation rules, expected behavior for missing fields, or how it interacts with other user management tools. The existence of an output schema does not compensate for missing operational details.

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 only 33% schema description coverage, the description adds no parameter information beyond the schema. It does not explain the purpose of fields like emails, active, or roles, leaving the agent without guidance on how to populate them correctly.

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 'Create a new SCIM user' clearly states the action and resource, distinguishing it from related tools like users_update or users_delete. However, it does not specify whether this is workspace-level or account-level, leaving ambiguity with the sibling account_users_create.

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 is provided on when to use this tool versus alternatives such as account_users_create, users_patch, or users_update. The description lacks context on prerequisites, side effects, or alternatives.

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