create_user_role

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

Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds minimal behavioral context beyond stating it creates a role. It does not disclose side effects, rate limits, or preview endpoint behavior.

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 concise but contains an inaccuracy in listing required parameters. It is front-loaded but not fully reliable due to the contradiction with the schema.

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?

The tool has 5 parameters and no output schema. The description covers basic creation but lacks details on return value, side effects, limitations of the preview endpoint, or how the optional userIds assignment works.

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?

While schema coverage is 100%, the description contradicts the schema by omitting orgUnitId from the listed required fields, stating only roleName, description, permissionIds as required. This misleads the agent about mandatory parameters.

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 'Create', the resource 'user role', and the scope 'for an organization unit'. It differentiates from sibling tools like get_user_role and list_user_roles by specifying creation.

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 lists required and optional parameters but provides no guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. Usage is implied for role creation but could be clearer.

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