create_realm_role

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

No annotations are provided, so the description must fully disclose behavior. It states it creates a role (write operation) and returns a status message, but it does not mention side effects, permissions required, idempotency, or what happens if the role already exists.

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, front-loaded with the purpose, and uses a clear Args/Returns structure. It contains no unnecessary words, though the format is slightly code-like.

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 5 parameters, no annotations, and many sibling tools, the description lacks completeness. It does not explain the meaning of 'composite' vs 'client_role' in this context, nor does it clarify the return value beyond 'Status message.' The 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?

Schema description coverage is 0%, so the description needs to compensate. It provides brief parameter descriptions (e.g., 'realm: Target realm (uses default if not specified)'), which adds some meaning. However, 'composite' and 'client_role' are only restated without explanation of their purpose in a realm role context.

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 'Create a new realm role,' which is a specific verb+resource. It distinguishes from sibling tools like 'create_client_role' and 'assign_realm_role_to_user' by specifying 'realm role.'

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 implies when to use (creating a realm role) but provides no explicit guidance on when not to use or how it differs from alternatives like 'create_client_role' or 'update_realm_role.' No comparison to siblings.

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