ungroup

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 only states 'releasing all its items' but does not clarify if the group object is deleted, if items are moved, or if there are side effects like losing group-level properties. No mention of error conditions (e.g., invalid index).

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 a single sentence of 8 words, highly concise and front-loaded. It conveys the essential purpose without extraneous text. Could be expanded slightly but efficiency is maintained.

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 no annotations, no output schema, and a simple operation, the description provides minimal but adequate information. However, it does not address the result or behavior beyond the core action, leaving some ambiguity about what 'releasing all its items' means practically.

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?

Both parameters have descriptions in the input schema (100% coverage). The tool description adds no additional meaning beyond those schema descriptions. Baseline 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 clearly states the verb 'ungroup' and the resource 'a group', with the result 'releasing all its items'. It distinguishes from sibling tools like 'create_group' and 'add_item_to_group'. However, it could be more precise about what 'releasing all its items' entails.

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 such as 'remove_item_from_group' or 'create_group'. No prerequisites mentioned (e.g., group must exist). The agent must infer usage from the name and description alone.

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