respond_to_event

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

With no annotations, the description carries the behavioral burden. It usefully discloses that send_response=False records the response without emailing the organizer, implying the default sends email. However, it does not explain the mailbox parameter, permission requirements, or what happens after a response is recorded.

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 opening sentence is front-loaded and the Args section is compact with no wasted words. It earns a strong score, though the Args list is incomplete since it omits event_id and mailbox, which slightly weakens the structure as a standalone guide.

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 tool with 5 parameters, no annotations, and no output schema, the description leaves notable gaps: event_id and mailbox are undocumented, and there is no indication of return values or effects beyond the send_response note. This is adequate for a simple call but not complete for confident autonomous invocation.

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 adds meaning for response, comment, and send_response, especially clarifying the send_response side effect. However, it omits event_id (a required parameter) and mailbox entirely, leaving their semantics to be inferred from names only.

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 ('Respond to a meeting invite') on a clear resource, and the phrasing differentiates it from sibling tools like update_event, delete_event, and cancel_event. An agent can tell this is the invitation-response tool rather than a general event mutation tool.

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 intended use is implied by 'Respond to a meeting invite', but there is no explicit guidance about when to choose this over alternatives, such as update_event, or when not to use it. No exclusions, prerequisites, or alternative tool mentions are provided.

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