calendars_create_event_notification

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

Annotations already declare readOnlyHint=false, indicating a write operation; the description adds no additional behavioral context. It does not disclose what a 'notification' is, what happens on creation, any prerequisites, side effects, or response behavior. With no extra information beyond the name and annotations, this dimension is essentially empty.

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 short, but this is under-specification rather than conciseness. It lacks all necessary detail and structure. While there is no wasted text, the brevity is detrimental; it provides only a minimal phrase that does not earn its place as a useful description.

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 create operation with two required parameters and no output schema, the description is grossly incomplete. It does not explain what a 'notification' is, how to construct the body, what the calendarId refers to, or what the expected result is. The tool cannot be correctly invoked based on this description alone.

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 only 50% (only 'body' has a description; 'calendarId' has none). The description provides zero additional explanation of the parameters. It does not clarify what the body array should contain or how calendarId is used. The tool description adds no semantic value beyond the schema, and it fails to compensate for the missing parameter documentation.

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 notification' is a verb plus a vague resource, but it fails to specify that this is about calendar event notifications. It does not distinguish from other notification-related tools or the many calendars_* siblings. The verb is clear but the object is too generic to convey the tool's actual function.

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 on when to use this tool versus alternatives. There are many sibling tools for calendars and notifications (e.g., calendars_create_event, calendars_create_calendar, calendars_get_event_notification), but the description gives no context on the intended use case or any conditions that would select this over others. Completely absent.

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