create_group

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

No annotations are available, so the description must fully disclose behavior. It states the tool 'creates' a group with a configuration, but does not mention error handling for duplicate names, required permissions, side effects, or response format. This lack of detail leaves significant behavioral gaps for the agent.

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 two concise sentences with no wasted words. The first sentence states the primary action, and the second provides valuable context about reusability, front-loading essential information.

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?

The description explains the high-level purpose but lacks completeness for a tool with 16 parameters and no output schema. It does not mention how the created group fits into the workflow (e.g., for delegation), nor what the tool returns. While the schema covers parameter details, the overall context of use could be more complete.

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?

With 100% schema coverage, the baseline is 3. The description adds no additional parameter details beyond what the schema already provides, which is sufficient but not enhanced.

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 action 'Create' and the resource 'named agent group' with additional context 'shared runtime config' and 'reusable presets for fractal orchestration'. It effectively distinguishes from sibling tools like list_groups, delete_group, and delegate_to_group.

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 implies usage by stating groups are reusable presets, but it does not explicitly specify when to use this tool versus alternatives (e.g., creating vs. listing or delegating). No when-not-to or prerequisite information is provided, leaving the agent with implied but not explicit guidance.

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