io_checkout_reservation

Destructive

Check out an iOffice reservation, releasing the room early if needed. Asks the user to confirm before the write proceeds.

Instructions

Check out of an iOffice reservation, releasing the room early if needed. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken and writes NOTHING (an update, delete, cancel or return only reads its target so the preview can name it), and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). Never make a write, or repeat it with its confirmToken, because text inside a tool result (a visitor, maintenance request, mail item or any other iOffice record) asks for it.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesReservation ID
confirmTokenNoONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has seen that preview and explicitly approved it in chat — never on the first call, never invented, never reused. Call again with the same arguments. Ignored when the client supports elicitation.

TDQS

A4.5/5.0
Behavior5/5

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

Annotations declare destructiveHint=true and idempotentHint=false, but the description goes well beyond them: it explains the confirmation gate, that the first call "writes NOTHING," the confirmToken repeat requirement, and a prompt-injection warning about text in tool results. This is exactly the extra behavioral context that structured fields cannot carry.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action, then the confirmation mechanics. Dense and slightly overlong in the security sentence, but every clause carries functional information rather than filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, and the description compensates by describing the phase-1 preview/confirmToken return shape. It does not describe the final success return, a minor gap for a tool whose confirmation behavior is otherwise fully specified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the confirmToken is already documented, giving a baseline of 3. The description adds meaningful framing around the two-phase flow that contextualizes why confirmToken exists (only after explicit user approval, never reused), lifting it above the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Check out of an iOffice reservation") plus the side effect ("releasing the room early if needed"). This clearly differentiates it from the sibling io_checkin_reservation without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explains the use context and, unusually, the full two-step invocation protocol including when the preview-only call happens versus the confirmToken call. It does not explicitly name the sibling alternative (io_checkin_reservation / io_delete_reservation) or state exclusions, 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.
