Respond To Calendar Event

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

With no annotations, the description carries full responsibility for disclosing side effects. It mentions the required permission but fails to state that this is a write operation that mutates the event, may notify the organizer, or that sendResponse defaults to true. This is insufficient 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 two sentences, front-loaded with the core action, and includes only essential information: the action, permission, and Chinese equivalents. There is no redundancy or filler, so every word earns its place.

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?

The description provides the essential purpose and permission, while the schema covers parameter details. However, it lacks usage guidelines versus alternatives, omits behavioral consequences (e.g., organizer notification), and there is no output schema or return value information. These gaps make it minimally viable, not fully complete.

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 coverage is 100%, so baseline is 3. The description adds value by mapping Chinese intents (接受会议邀请, 拒绝会议邀请, 暂定会议) to the response enum values, aiding interpretation of non-English requests. This goes beyond the schema's plain descriptions and helps with parameter selection.

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 explicitly identifies the action (accept, tentatively accept, or decline) on a meeting invitation, making it clear what the tool does. It distinguishes itself from sibling calendar tools like create/update/cancel event by focusing on the 'respond' action, and the addition of Chinese intents further clarifies the scope.

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 states a required permission (delegated Calendars.ReadWrite) but does not explicitly say when to use this tool versus alternatives. No exclusions or alternative tool references are provided, so usage context is implied by the name and sibling list rather than clearly described.

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