create_role

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

With no annotations provided, the description carries the full burden of disclosing behavior. It does not mention potential side effects, permission requirements, rate limits, or what happens on failure (e.g., duplicate role names). The description is too brief to inform the agent about behaviors beyond the basic action.

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 extremely short and to the point, with no redundant information, but it is under-specified. It front-loads the core action but lacks necessary context, so it is not as helpful as a slightly longer version that adds usage or behavioral details.

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 moderate complexity (7 parameters, output schema exists), the description is insufficient. The output schema exists, so return values are partially covered, but the description does not address how parameters interact, what the response contains, or any constraints. For a creation tool, more context is needed to ensure correct 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 schema covers 0% of parameters in the description, so the description must compensate, but it does not. It mentions no parameter details at all, leaving the agent to infer meaning from the schema. With 7 parameters, this is a significant gap. Even the default values are present in the schema, but the description does not clarify concepts like 'hoist' or 'mentionable' 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 clearly states the action ('Create a new role') and the resource ('in the server'), distinguishing it from sibling tools like assign_role, remove_role, and list_roles. It does not explicitly contrast with these alternatives, but the verb 'create' plus 'role' sufficiently conveys its function.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., required permissions, existing guild context), nor does it explain when to choose create_role over assign_role or edit_channel. The description is minimal and lacks contextual usage instructions.

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