get_event_details

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

No annotations are provided, so the description carries full burden of behavioral disclosure. It doesn't mention that this is a read-only operation, whether events can be from any calendar, what happens if no event matches the ID, or what fields of detail are returned. For a retrieval tool with no annotation coverage, this is thin.

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?

A single efficient sentence with zero waste. It gets to the point quickly. The structure is fine but could arguably include slightly more detail without becoming verbose.

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?

This is a relatively simple lookup tool with 100% schema coverage, an output schema, and a clear purpose. The description is minimal but arguably sufficient for a basic retrieval operation where the output schema documents return values. However, it could note sibling differentiation given the crowded calendar-tool space.

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 description coverage is 100%, with all 3 parameters documented in the schema (account, event_id, calendar_id with default). The description itself doesn't add param info, but baseline 3 applies with full coverage, and the calendar_id default-to-primary behavior is useful context already in schema. Baseline 3 is appropriate here.

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 states 'Get detailed information about a specific calendar event' with a clear verb+resource. However, it doesn't distinguish from siblings like get_today_events, get_upcoming_events, and get_week_events, all of which are event-related tools. The purpose is clear but generic.

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 on when to use this tool versus siblings like get_today_events or get_week_events. The name suggests it's for a single specific event, but the description doesn't clarify that this is for retrieving details on one event by ID rather than listing events by date range.

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