calendars_create_calendar_group

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

The description adds no behavioral information beyond what the annotations already provide. Annotations indicate it's a non-read-only, open-world, non-idempotent, non-destructive creation operation, but the description does not elaborate on side effects, permission requirements, or any post-creation implications. With no added context, the description fails to enhance transparency beyond structured fields.

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, technically concise, but it is under-specified to the point of being content-free. It offers no explanation of what a calendar group is, what fields are needed, or any operational details. This is not genuine conciseness but sparse inadequacy, warranting a low score.

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 creation tool with 5 parameters and no output schema, the description is drastically incomplete. It does not explain the concept of a calendar group, the significance of required fields (name, slug, description), or expected outcomes. An agent has no way to correctly invoke this tool based on the description alone, making it contextually insufficient.

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 input schema has 5 parameters with only 20% description coverage (only locationId has a description). The tool description does not mention any parameter, their purpose, or how they relate to creating a calendar group. Since schema coverage is low and the description provides zero compensation, parameter semantics are entirely unaddressed.

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 Calendar Group' restates the tool name verbatim (calendars_create_calendar_group) without adding any detail. It names the verb and resource but provides no differentiation from siblings like calendars_create_calendar, which could plausibly be confused for an identical purpose. This is essentially a tautology, offering no new information.

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?

There is no guidance whatsoever on when to use this tool versus alternatives. The description does not mention when to create a calendar group as opposed to a calendar, schedule, or other related creation operations. No context, prerequisites, or exclusions are provided.

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