create-specific-calendar-event

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

Annotations already indicate destructiveHint=true and readOnlyHint=false, so the description's mention of 'create' is consistent. However, it adds no further behavioral details such as what happens to existing events, permissions required, or response behavior, beyond what annotations already imply.

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 concise with one sentence and a bulleted tip. It's front-loaded with the core purpose. However, it could be more structured, e.g., separating usage notes from the main description.

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 complex input schema with nested objects and many properties, the description is minimal. It lacks details on required fields, how to structure the request body, and what the response contains. The tip is helpful but insufficient for a complex tool.

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 has 75% parameter description coverage, so the description does not need to add much. The tip about using list-users for email addresses aids understanding of the attendees parameter but is not directly part of parameter documentation. Overall, it provides marginal additional meaning.

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 it creates a new event in a calendar, specifying that the calendar can be for a user or a Microsoft 365 group. However, it does not explicitly differentiate from the sibling 'create-calendar-event', leaving ambiguity about what makes this tool specific.

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?

The description provides a critical tip advising not to guess email addresses and to use the list-users tool instead. This gives concrete guidance for correct usage, but it does not specify when to use this tool over alternatives like 'create-calendar-event'.

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