respond_to_meeting

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 declining records an answer rather than cancelling the meeting, but it does not explain update semantics, idempotency, permissions, or the meaning of PENDING beyond the enum.

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 with no filler; the main purpose and the critical caveat are front-loaded. Every sentence contributes information.

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 simple two-parameter tool, the description, together with the schema enum and required fields, is nearly complete. The key caveat about declining is present; only minor gaps such as PENDING semantics and return behavior remain, and no output schema exists to require more.

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 some meaning by tying response to RSVP values and clarifying the effect of DECLINED, but it does not describe the meetingId format or explain when PENDING should be used.

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 the specific action ('Record RSVP'), the resource ('meeting'), and enumerates the valid response values. This clearly differentiates it from sibling tools like create_meeting or list_meetings by establishing it as a meeting-response tool, not a scheduling or query 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 description implies the tool is for submitting a meeting invitation response and explicitly clarifies that declining does not cancel the meeting. However, it does not state when to prefer this over alternatives, how to obtain a valid meetingId, or whether the tool is also used to update an existing RSVP.

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