update-specific-calendar-event

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

Annotations already indicate this is a write operation (readOnlyHint=false) and destructive (destructiveHint=true). The description adds transparency about the attendee list being replaced in full, which is valuable. However, it does not mention other side effects like sending updates to attendees or impact on recurrence.

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 relatively concise with a tip and warning, but the first sentence is vague and wastes space. The structure could be improved by leading with a clear purpose statement.

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's complexity (5 parameters, nested objects, high mutation potential), the description fails to cover important context like required fields, return values, or typical use cases. The schema and annotations fill some gaps, but the description should provide a bigger picture.

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 80%, and the description adds one useful warning about the 'attendees' parameter. However, it does not add meaning for many other parameters like eventId, calendarId, or the complex body structure, which are already documented in the schema.

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 'Update the navigation property events in me' is vague and does not clearly state that the tool updates a specific calendar event. It fails to distinguish this tool from similar siblings like 'update-calendar-event' or 'delete-specific-calendar-event'.

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 includes a tip about using list-users tool and a warning about attendee replacement, but it gives no guidance on when to use this tool versus alternatives like 'update-calendar-event' or 'create-calendar-event'. The tip is operational, not comparative.

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