create_group

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

No annotations are provided, so the description must convey behavioral traits. It only states 'Create a new group' without details on idempotency, permissions, side effects, or whether the group is operational immediately. This is insufficient for safe invocation.

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 very short and front-loaded, but it includes an unnecessary 'Args:' section that just repeats the schema. Still, it is concise. However, the structure could be improved by integrating param docs into the main description.

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's simplicity (2 params, output schema exists), the description still fails to cover essential aspects like return value structure, error conditions, or the effect of creating a group on permissions. It is incomplete for an agent to use confidently.

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 should compensate. However, it merely restates param names ('groupid: Group ID. comment: Description.') without adding meaning beyond the schema fields. The parameter 'comment' is noted as 'Description', but the schema already indicates it's a string with a default. No semantic value added.

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 a new group' clearly states the action (create) and the resource (group). Among siblings like create_user, create_role, the purpose is distinct. However, it lacks context on what a group represents (e.g., access control), but the verb+resource is specific enough.

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 on when to use create_group versus alternatives or prerequisites. There is no mention of when not to use it or which scenarios it suits, relying entirely on the agent to infer.

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