io_update_visitor

Destructive

Update an existing iOffice visitor record by passing only the fields to change, with a user confirmation required before any write.

Instructions

Update an existing iOffice visitor record. Only provide fields to change. 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 makes NO network call, 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.

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 only say readOnlyHint=false / destructiveHint=true; the description adds real behavioral depth: an elicitation-based confirmation prompt, a preview-only phase-1 that makes no network call, a confirmToken that must be echoed, and an explicit prompt-injection warning. This is substantial context beyond the structured hints and is consistent with them.

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?

Purpose is front-loaded and the confirmation mechanics are compact given their complexity. The final injection-warning sentence is long and slightly convoluted, but every sentence carries operational value.

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?

For an update tool with no output schema, the description covers the write path, the two-phase confirmation contract, and the safety warning. It does not describe success/error behavior on an invalid id or unknown fields, which is a minor gap.

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 baseline is 3, but the description clarifies partial-update semantics ('Only provide fields to change') and the confirmToken's role in the fallback flow — meaning not fully conveyed by the field descriptions alone.

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?

Specific verb+resource ('Update an existing iOffice visitor record'), immediately distinguishable from io_get_visitor, io_create_visitor, io_checkin_visitor and io_checkout_visitor. The closing note that only changed fields need supplying sharpens the scope further.

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?

Gives concrete usage guidance ('Only provide fields to change') and spells out the when/how of the confirmation flow, including the two-step fallback condition. It stops short of naming when to use a sibling (e.g. check-in/check-out) instead, so it is clear context without explicit alternatives.

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