calendar_delete_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. It states the action 'Delete a calendar event' but does not mention whether the deletion is permanent, whether it affects the entire series or only instances, or any side effects. This is a significant gap for a destructive operation.

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, concise sentence with no unnecessary words, which is structurally fine. However, it is so brief that it omits critical information, making it under-specified rather than effectively concise.

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 destructive tool with no annotations and an output schema, the description is incomplete. It does not explain the implications of deletion, such as irreversibility, effects on recurring events, or what the response contains. An agent would have insufficient information to use this tool safely and correctly.

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 schema description coverage is 0%, meaning the schema provides no explanations for event_id or calendar_id. The tool description adds no parameter details, such as how to obtain an event ID or what calendar_id defaults to. The description fails to compensate for the lack of schema descriptions.

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 uses the specific verb 'Delete' and identifies the resource as 'a calendar event,' making the tool's function immediately clear. It also distinguishes itself from sibling tools like calendar_update_event and calendar_get_events by clearly targeting a delete operation.

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 alternatives, no mention of exclusions or prerequisites, and no indication of scenarios where deletion might be inappropriate (e.g., recurring events or events shared with others). It simply states the action without any usage context.

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