m365_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. It reveals only that the target is a 'connected' M365 calendar (a hint at an auth/connection prerequisite) and that this is a mutation; it says nothing about required permissions, whether invites are sent, reversibility, or what the call returns.

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 or repetition. It is efficient, though the terseness is part of the problem rather than a virtue here.

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 write operation with no annotations, no output schema, and an empty parameter object, the description is far too thin. It omits connection prerequisites, creation semantics, and any explanation of how the event payload is provided, leaving the agent unable to invoke the tool correctly.

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 declares zero parameters, which normally earns a baseline of 4, but for a creation tool an empty schema is anomalous: the description never explains how event fields (title, time, attendees) are supplied. It therefore adds no compensating meaning for the one thing an agent most needs to know.

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 sentence names a specific verb (Creates) and resource (event) within an explicit container (connected Microsoft 365 / Outlook calendar), so the core action is unambiguous. However, it does nothing to separate this tool from near-identical siblings such as outlook_calendar_create_event, create_calendar_event, and m365_list_events, so an agent cannot tell which calendar-creation tool to pick.

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 prerequisite (e.g. connect_m365_account must run first), and no mention of alternatives despite a crowded calendar/event sibling set. The agent is left to infer everything from the name alone.

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