create_role

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

The description states it creates a role, implying a write operation, but no further behavioral details are given (e.g., idempotency, permissions required, side effects). Since no annotations exist, the description should carry the full burden, but it does not.

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 with two sentences and a parameter list, but it sacrifices completeness. It could be more informative without being overly 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 the simplicity of the schema and existence of an output schema, the description fails to cover important context like uniqueness constraints, error conditions, or typical usage patterns for role creation.

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 schema coverage at 0%, the description adds minimal value. It provides an example format for 'privs' but does not explain 'roleid' semantics or acceptable privilege values beyond the example.

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 the verb 'Create' with the resource 'role', making the purpose clear. However, it does not explicitly distinguish from sibling tool 'update_role', which could cause confusion for an agent deciding between creation and modification.

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 vs alternatives like update_role. There is no mention of prerequisites, such as ensuring the role doesn't already exist, or when not to use it.

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