get_calendar_event

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

No annotations are provided, so the description carries the full behavioral burden. It only says it 'Returns event details' and does not disclose permission requirements, error behavior for an invalid/nonexistent ID, or any other operational trait an agent would need.

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 purpose is front-loaded, but the same idea is repeated four times ('by ID | specific event, event details | Use to get full details | Returns event details'), and the Args/Returns block duplicates both the description and the existing output schema. Redundant rather than tight.

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 simple single-parameter getter with an output schema present, the description covers the basics without needing to explain return values. It is minimally viable but omits error/failure semantics and any differentiation from the numerous similar event tools.

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 0%, so the description must compensate for the lone parameter, yet it only repeats 'event_id: The calendar event ID' — a restatement of the property name with no added format, range, or sourcing detail. It fails to add meaning beyond 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 states a specific verb+resource ('Get calendar event by ID') and clarifies it returns full details of a specific event, so the agent knows exactly what it does. However, it never distinguishes itself from the many similar siblings (get_event_by_id, get_events, search_calendar), so an agent cannot tell which sibling to pick from the description alone.

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?

'Use to get full details of a specific calendar event' implies the use case (single event, full detail) but gives no when-not guidance and names no alternatives among the crowded calendar/event sibling set. Usage is inferable but not explicit.

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