outlook_calendar_create_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, and it discloses almost nothing: no permission/account requirements, no note on whether the event is sent as an invite, no recurrence or timezone behavior, and no indication of what happens on success. One sentence of pure intent is far short of what a mutation tool with zero annotation coverage needs.

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 front-loaded sentence with no filler, which is efficient. It is, however, only minimally informative rather than deliberately concise, so it does not reach a 5.

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?

With no annotations, no output schema, an empty input schema, and a crowded field of sibling calendar-creation tools, the definition is not sufficient for an agent to call this tool confidently or route to it correctly. Essential context about account binding and how event data is passed is missing.

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 declares zero parameters, so per the baseline this dimension defaults to 4 — there is no parameter set for the description to clarify. That said, a create-event tool with an empty schema is itself surprising, and the description does not explain how event details (subject, time, attendees) are supplied.

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?

States a specific verb and resource ('Creates a calendar event in Microsoft Outlook'), so the basic action is unambiguous. However, it does nothing to distinguish itself from near-identical siblings such as create_calendar_event, m365_create_event, and the paired update_calendar_event / delete_calendar_event, leaving the agent to guess which vendor surface to use.

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?

There is no when-to-use guidance, no prerequisites (e.g. connected Outlook account), and no mention of alternatives despite several competing 'create event' tools in the sibling list. Usage must be entirely inferred from the name.

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