create_calendar_event

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

The description only says 'Create', which implies mutation, but does not disclose any additional behavioral traits such as permission requirements, idempotency (e.g., whether creating with the same title may fail or overwrite), or what happens to optional fields if omitted. With no annotations, this is insufficient for safe invocation.

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, concise and front-loaded with the core action. It wastes no words, though it could include more context without sacrificing brevity.

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?

Given the tool has 7 parameters, no output schema, and no annotations, the description is too minimal. A create tool should explain what the event will contain (e.g., created with specified fields), and whether it returns the created event or an ID. The current description leaves the agent guessing.

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 covers all 7 parameters with clear descriptions, achieving 100% coverage. The description adds no extra meaning beyond the schema, so it meets the baseline expectation but does not enhance understanding.

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 the verb 'create' and the resource 'calendar event', making the tool's purpose immediately understandable. However, it lacks specificity about what can be customized (e.g., participants, location), which is covered by the schema but not highlighted in the description.

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 like 'list_calendar_events' or 'get_calendar_event'. There is no mention of prerequisites, such as needing a calendar ID, or when it might be inappropriate to use.

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