group_create

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

No annotations are present, so the description must fully disclose behavior. It only states 'creates a new group' but does not mention side effects, required permissions, rate limits, or the return value. The mutation nature is implied but not elaborated.

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, with no wasted words. However, the extreme brevity sacrifices essential information, making it less helpful than a longer but more complete description would be.

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 4 parameters, no output schema, and no annotations, the description is grossly incomplete. It does not describe what the tool returns, the meaning of optional parameters, or any behavioral expectations, leaving the agent with insufficient information for correct invocation.

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%, leaving the description to explain all parameters. It only explains group_name; about, project_id, and is_approval are left undefined. Their types (string, integer) offer no semantic meaning, so the agent cannot correctly infer how to fill them.

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 tool creates a new group, and identifies the required parameter group_name. The verb 'create' and resource 'group' are specific, and the tool name itself is unambiguous, differentiating it from other group-related siblings like group_create_discussion.

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 provided on when or when not to use this tool, nor does it compare to alternatives. For example, it doesn't mention whether this is for creating a top-level group or one associated with a project, or if other permissions are needed.

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