createGroup

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

With no annotations and no behavioral details in the description, the agent is left completely in the dark about potential side effects, permissions, or error conditions. The description adds no transparency beyond the bare action.

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 extremely under-specified, consisting of only three words. While it is concise in length, it lacks necessary substance, making it ineffective rather than appropriately sized.

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's low complexity, a short description could suffice, but this one omits even basic context about what a 'group' is or what the operation entails. With no output schema and no annotations, the description fails to provide a complete picture for an agent.

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 100%, so the input schema already documents both 'name' and 'userIds'. The description adds no parameter information, meeting the baseline of 3 for high schema coverage.

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' is essentially a tautology of the tool name 'createGroup'. It states the verb and resource but adds no distinguishing scope or details, failing to differentiate from sibling create tools like createPersonAttachment or createTeam.

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 context is provided about when to use this tool versus alternatives. The description neither states scenarios nor exclusions, leaving the agent without guidance on selecting this tool among many similar create operations.

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