create_group

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

No annotations are provided, so the description must disclose behavioral traits. It states 'Create a group' but does not explain whether the selected items are moved into a new group object, whether the group becomes the active selection, or any side effects like item hierarchy changes. The mutation aspect is implied but not detailed.

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 brief (one sentence) and front-loaded, but it is under-specified. While it avoids verbosity, it lacks essential details that would make it helpful, so conciseness does not equate to completeness.

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 tool with one parameter and no output schema, the description should clearly explain the selection prerequisite, the role of the page index, and what the resulting group represents. It fails to cover these aspects, leaving the agent with insufficient context to use the tool correctly.

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?

The schema provides 100% coverage for the single parameter 'pageIndex', but the description does not mention this parameter at all. It misses the opportunity to explain that the group is created on the specified page and that the selected items must reside on that page. Thus, the description adds no meaning beyond the schema.

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 group from currently selected items' conveys a basic purpose, but it does not specify what types of items can be grouped or how the pageIndex parameter relates to the selection. The sibling tool 'create_group_from_items' suggests alternative grouping methods, but the description fails to clarify the distinction, making the purpose moderately clear.

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 this tool versus alternatives like 'create_group_from_items' or 'add_item_to_group'. The description implies that items must be selected beforehand, but does not explicitly state this prerequisite or provide any usage context. This leaves the AI agent without clear decision criteria.

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