rm_create_role

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

Annotations already convey that this is a non-read-only, non-destructive write, and the description adds no further context such as duplicate-name handling, uniqueness rules, or permission requirements. With openWorldHint=true signaling variable behavior, additional behavioral disclosure would have been valuable but is absent.

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?

A single front-loaded sentence with no wasted words; efficiency is excellent. It is merely under-specified in content, which is penalized in other dimensions rather than here.

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 one-parameter create operation with an output schema and annotations covering the safety profile, the essentials are present. The notable gaps are duplicate-name behavior and any prerequisites, which matter more given openWorldHint=true.

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 for the single 'name' parameter is 0%, and the description says nothing about its meaning, format, uniqueness, or length beyond what the parameter name already implies. The description fails to compensate for the schema gap.

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?

States a specific verb ('Create') and resource ('role'), and is easily distinguished from siblings rm_update_role, rm_delete_role, and rm_list_roles. However, the sentence adds essentially nothing beyond the tool name itself, so it stops short of a 5.

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?

Provides no guidance on when to call this tool versus rm_update_role or rm_list_roles, and mentions no prerequisites or exclusions. An agent gets no hint about whether it should check for an existing role first or when creation is the appropriate choice.

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