Respond to calendar event invite

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 falls short. It never states that this mutates your attendee record on the event, that sendUpdates defaults to none (so invitees may not be notified), or whether the change is reversible. Only the mechanism (setting responseStatus) is disclosed.

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 efficiently front-loaded sentence with no filler; the action set leads and the mechanism follows. It could be one notch richer without bloating.

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 mutation tool with zero annotations and no output schema, the definition is adequate but thin: it omits side effects (notification behavior, whose attendee entry is affected) and return information. An agent can invoke it, but not with full confidence about consequences.

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 100%, with documented enums for responseStatus and sendUpdates and clear notes for email, account, and calendarId defaults. The description adds the responseStatus semantics but nothing beyond what the schema already conveys, so baseline 3 applies.

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 action set (accept, decline, mark tentative) on a specific resource (an event invite) via the responseStatus field. It is clearly distinguishable from generic calendar mutators like update_event, though it never names a sibling explicitly.

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?

Usage is implied by the verb set: you call this when you want to RSVP to an invite. There is no explicit when-to-use versus google_calendar_update_event, no note that this targets your own attendee entry rather than the event body, and no prerequisites.

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