calendar_create_calendar

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

No annotations provided, so the description carries full burden. It fails to disclose key behavioral traits such as permissions required, error conditions (e.g., if a calendar with the same summary exists), or the response/return value. Only states the basic 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 concise at 4 words, with no unnecessary content. While it is front-loaded and efficient, it sacrifices valuable context that could be added without significant length.

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 output schema and simple parameters, the description lacks completeness. It does not mention what the tool returns (e.g., calendar ID), whether it creates a secondary calendar, or any side effects. More context is needed for an agent to fully understand the tool's behavior.

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%, with each parameter having a clear description. The overall description adds no extra meaning beyond the schema, meeting baseline expectations. No contradictions or missing parameter info.

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 new Google Calendar' uses a specific verb and resource, clearly stating the action. It distinguishes from sibling tools like calendar_delete_calendar, calendar_update_calendar, etc., but does not explicitly mention the scope or uniqueness.

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. For example, it does not specify that this creates a secondary calendar (not the primary), or any prerequisites like authentication or scopes.

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