create_calendar_notification

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

No annotations are provided, so the description carries full burden. It includes the tag '[mutation]' but fails to disclose side effects (e.g., whether existing settings are overwritten), required permissions, or any rate limits. It only states the basic creation action without deeper behavioral context.

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 with a dash-separated list of types, front-loaded with the main action. It is concise and avoids unnecessary words, though the mutation tag slightly clutters the structure.

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 lacks information about return values—since there is no output schema, it should state what the tool returns (e.g., the created notification object). It also does not mention prerequisites like the existence of the calendar or required access permissions, which are important for a creation tool.

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 coverage is 100% with all parameters described. The description adds no additional meaning beyond the schema; it merely repeats the types. According to the rubric, high schema coverage baseline is 3, which is appropriate here.

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 that the tool creates an automatic notification for a calendar and lists the notification types (confirmation, reminder, cancellation, follow-up, no-show). It uses a specific verb 'creates' and resource 'calendar notification', distinguishing it from other calendar-related tools like create_calendar_event.

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 provides no guidance on when to use this tool versus its siblings (e.g., update_calendar_notification, delete_calendar_notification). There is no mention of prerequisites or scenarios where this tool should not be used.

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