Create group

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

The description offers no behavioral details beyond the fact that a group is created. Annotations already indicate it's not read-only (readOnlyHint: false), but the description doesn't disclose effects like how parent_id influences creation, potential uniqueness constraints, or any side effects. The API endpoint is a technical detail, not a behavioral trait.

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, which is good, but it contains clear redundancy: 'Create group' and 'Creates a new group' say the same thing. The phrase 'Level API endpoint' is awkward and unclear. It could be more concise and structured by removing duplication and explaining the endpoint clearly.

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 simple create operation with two parameters, the description is minimal and does not contextualize the tool within the broader API. It doesn't explain what a group is, what creating one implies, or how the parent_id parameter affects the outcome. The schema provides some parameter details, but the description itself is inadequate for a complete understanding.

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 description adds no parameter information beyond the schema. With schema coverage at 50% (and the description not compensating), the agent gets no additional context about how to fill parameters or what behaviors they trigger. The parent_id semantics are left entirely to 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 clearly states the action (create) and the resource (group), but 'Create group' and 'Creates a new group' are redundant and essentially restate the tool name. The API endpoint 'POST /v2/groups' adds some specificity, but there is no meaningful differentiation from sibling tools other than the resource name.

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 about when to use this tool versus alternatives. It does not mention prerequisites, use cases, or exclusions. The usage is only implied by the name and basic action, which is insufficient for an agent deciding between this and other create tools.

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