respond-to-calendar-event

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

The description adds behavioral context beyond the annotations: it discloses that the organizer is notified, that it is a WRITE operation, and that a confirmation flag is required. This aligns with readOnlyHint=false and destructiveHint=false, with no contradiction.

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?

Two short sentences convey the action, options, side effect, and safety gate with no wasted words. Key information is front-loaded in the first sentence.

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 covers the essential calling context: what the tool does, the required response values, the side effect, and the confirm requirement. It does not describe the return value, but without an output schema this is a minor gap for a simple write action.

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%, so the schema already documents each parameter. The description repeats the enum values but adds no new meaning beyond what the schema provides.

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 names a specific verb ("Respond") and resource ("meeting invitation"), enumerates the exact actions (accept / decline / tentativelyAccept), and notes a side effect (organizer notified). This clearly distinguishes it from sibling tools like create-calendar-event or update-calendar-event.

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 context is explicit: it is used to respond to a meeting invitation, and it states the safety precondition (confirm=true). However, it does not explicitly contrast with alternative tools or state when not to use it, so it falls short of a 5.

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