Creating a role

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

The annotation destructiveHint=true indicates destructive behavior, and the description adds 'Perm: manage_roles' hinting at required permissions. However, it does not explain the nature of the destruction (e.g., overwriting existing roles), rate limits, or side effects beyond what annotations already imply.

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 very short but incomplete (truncated sentence 'Creates a new...'), sacrificing essential information. It is not well-structured and the opening phrase 'Creating a role' is redundant with the title.

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?

For a destructive tool with 3 parameters including a nested object body, the description lacks details about the body schema, the role creation process, and safety mechanisms like confirm and dry_run. An output schema exists but is not referenced.

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 covers all three parameters with descriptions (body, confirm, dry_run). The tool description adds no additional parameter meaning, such as format or constraints, so baseline 3 is appropriate given 100% schema coverage.

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 states 'Creating a role' and 'Creates a new...', indicating the verb and resource. However, the sentence is truncated and lacks specificity about what a role is in this context, and it does not differentiate from the many other create_* sibling tools.

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 action1_create_user or action1_create_package. There is no mention of prerequisites, limitations, 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.
