create_calendar_event

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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet it only restates the creation action. It does not mention required permissions, side effects, whether the event is published or draft, calendar ownership, or what happens on duplicate times.

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 text is brief but this is under-specification rather than concise completeness. One short sentence fails to provide front-loaded details about required fields, behavior, or response.

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 write tool with six parameters, three required fields, no output schema, and no annotations, 'Create a calendar event' is inadequate. The agent lacks information about required input semantics, call effects, and expected return value.

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 provides descriptions for all six parameters, including formats like ISO 8601 and an example context code. The description adds no parameter-level meaning, but the high schema coverage keeps this at baseline.

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 calendar event' is a near-verbatim restatement of the tool name and adds no distinguishing detail. It identifies the action and resource but does not differentiate this from other create tools or explain what kind of calendar event is involved.

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 on when to use this tool versus alternatives such as list_calendar_events or other create_* tools. No conditions, prerequisites, or exclusions are given, so the agent must infer usage entirely from the operation name.

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