create_group

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

The description only states the basic function. With openWorldHint: true, more context about side effects or permissions would be valuable. No additional behavioral traits beyond the obvious creation action are disclosed.

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 concise—one short sentence that directly states the tool's purpose. It is efficient and front-loaded with the key verb and resource.

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 tool has 5 parameters, no output schema, and no annotations about return values or errors, the description is too sparse. It does not cover what the tool returns, potential errors, or prerequisites (e.g., authorization to create groups).

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 coverage is 100% and the input schema already provides descriptions for all parameters. The description does not add any new meaning beyond what the schema offers, so baseline score 3 is appropriate.

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 'Create new group or subgroup' clearly identifies the action (create) and resource (group/subgroup). It distinguishes this tool from sibling tools like create_issue or create_label. However, it could be slightly more specific about the context (e.g., 'in GitLab').

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 provides no guidance on when to use this tool versus alternatives. With many sibling creation tools, the agent would benefit from conditions or prerequisites, but none are mentioned.

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