add_realm_role_composites

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

Without annotations, the description carries the full burden of behavioral disclosure. It only states 'add composites' without detailing side effects (e.g., overwriting existing composites), authorization needs, or error scenarios (e.g., role not found). The description adds minimal behavioral insight.

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 sentence, which is concise, but it under-specifies the tool's functionality. It is not wasteful, but it sacrifices completeness for brevity. A more structured description could improve clarity.

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 presence of a nested object parameter and no output schema or annotations, the description is insufficient. It does not explain the structure of the 'roles' object, return values, or error conditions. Sibling tools exist, but no differentiation is provided. The description lacks completeness for effective use.

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 already covers all parameters with clear descriptions (realm, role_name, roles as list of role representations). Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond the schema.

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 'Add composites to a realm role' clearly states the action (add) and the resource (composites to a realm role). However, it does not differentiate from sibling tools like add_client_role_composites or add_role_by_id_composites, which have similar purposes. The specificity of 'realm role' helps but lacks distinction.

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. There is no mention of prerequisites, exclusions, or context (e.g., when to use add_realm_role_composites vs. add_client_role_composites). The description offers no usage context.

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