respond_event

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

Annotations already indicate readOnlyHint=false and openWorldHint=true, so the agent knows it is a mutation with potential external side effects. The description adds the allowed response values but does not disclose other important behaviors, such as how send_response affects whether the response is delivered. No contradiction with annotations, but limited added transparency.

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 extremely concise, with two short sentences containing only essential information. The action verb and resource are front-loaded, and the list of valid response values is directly useful. No wasted words.

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 tool has 4 parameters, no output schema, and zero schema descriptions, the description feels incomplete. It doesn't cover the meaning of 'send_response' or 'comment', nor what constitutes a successful response. For a mutation tool with external side effects, this is insufficient for reliable agent use.

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 0%, so the description must compensate. It explains the 'response' parameter with enum values, but completely ignores 'comment' and 'send_response', which are not self-explanatory. 'send_response' in particular controls whether the response is actually sent, and leaving it undocumented is a significant gap.

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 the action: 'Respond to a meeting invite' and specifies the valid response values (accept, decline, tentative). This distinguishes it from sibling tools like update_event or create_event, as it is uniquely about responding to an invitation.

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 implies when to use the tool (when you need to RSVP to a meeting invite) but does not explicitly contrast it with alternatives like update_event or mention when not to use it. It provides basic context but lacks clear exclusions or alternative guidance.

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