create_user_event

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

No annotations are provided, so the description bears full responsibility for behavioral context. It only states the creation action, without mentioning permissions, side effects (e.g., whether updates are auditable), rate limits, or confirmation behavior. The agent has no insight into prerequisites or consequences beyond the basic 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?

Single sentence of 7 words, directly stating the tool's function. No extraneous information. Perfectly 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?

The tool has no output schema and moderate complexity with 5 parameters. The description does not mention expected return value (likely the created event object) or any behavior after creation (e.g., confirmation, recurrence support). While the schema provides parameter details, the description lacks completeness for an agent to fully understand the tool's outcome.

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?

All parameters are fully described in the input schema (100% coverage). The description adds no additional semantic context beyond stating the purpose. Schema already documents data types and examples (e.g., ISO 8601 format for dates), so the description's contribution is minimal.

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?

Description clearly states the tool creates a calendar event on a user's personal calendar, using a specific verb and resource. It is distinguishable from sibling tools like 'create_event' (likely for team calendars) and 'create_online_meeting' (a different type).

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 explicit guidance on when to use this tool versus alternatives like 'create_event'. The intended use case is implied by the name and description but not clarified, leaving ambiguity for an AI agent.

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