create_role

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

The annotations already indicate a non-readonly, non-destructive create operation, and the description adds little beyond that. It does not disclose required permissions, what happens on failure, whether the role is immediately usable, or how the created role relates to other role operations.

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 concise sentence with no filler. It front-loads the core purpose and does not waste tokens.

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?

With an opaque data object, no output schema, and no mention of return value or error behavior, the description is under-specified. An agent would still need external Discord API knowledge to know which role fields are supported and what the tool returns.

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 carries the compensation burden, but it does not explain the guild_id parameter or the structure of data. The phrase 'Discord role fields' loosely suggests that data contains role properties, but it is far too vague to clarify required or optional role field semantics.

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 identifies the action ('Create') and the resource ('a server role'), which is enough to distinguish from sibling tools like list_roles, add_member_role, and remove_member_role. However, it does not explicitly differentiate itself from any alternative or explain what 'Discord role fields' means in practice.

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 given about when to use this tool versus alternatives such as add_member_role or discord_request. It neither states prerequisites (e.g., required permissions) nor explains when this tool is the correct choice.

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