outlook_create_calendar_event

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that the tool creates and schedules, but does not mention side effects like sending invitations, modifying the calendar, permission requirements, or whether online meeting creation involves additional steps. This is a significant gap for a mutation tool.

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, tight sentence that directly conveys the core function. There is no wasted wording or repetition of schema details. It is appropriately front-loaded and easy to parse.

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 (7 parameters, no annotations, no parameter descriptions), the description is severely under-specified. It does not explain required inputs, datetime format, attendee handling, or behavior for optional fields. The presence of an output schema covers return values, but the description still fails to provide essential context for correct invocation.

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 schema has 0% description coverage across 7 parameters, and the description adds no parameter information at all. It does not mention subject, start/end datetime, attendees, location, body, or online meeting. The word 'schedule' hints at time parameters but provides no format or semantics beyond what the schema's field names already imply.

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 action ('Create and schedule') and the resource ('meeting or event in Outlook Calendar'). This distinguishes it from sibling tools like outlook_list_calendar_events and outlook_send_mail, which perform different operations. The verb-resource combination is specific and unambiguous.

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. The description does not mention any preconditions, expected use cases, or exclusions (e.g., when to use outlook_send_mail instead). There is no context about scheduling meetings versus simple events or how attendees are handled.

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