kia_forget_session

Idempotent

Discard the locally stored Kia session token to recover when login no longer works. Next Kia call requires MFA again. Only affects this machine; confirmation required before deletion.

Instructions

Discard the locally stored Kia session (the remember-me token), so the next Kia call needs the one-time MFA bootstrap again. This is the recovery path when the stored token no longer works — Kia revoked it, the password changed, or the account moved to another device — and the only alternative is deleting the session file by hand. It makes NO network call: Kia is not told anything, only this machine forgets. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call makes NO network call and returns a preview plus a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). Nothing is deleted until it is confirmed.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
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

A4.7/5.0
Behavior4/5

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

Annotations already indicate idempotentHint=true and destructiveHint=false, but the description goes beyond by stating it makes NO network call and includes a confirmation step, which is critical behavioral context. Some ambiguity about the confirmation flow (client-dependent) is acknowledged, but the description handles this well.

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?

The description is verbose but each sentence carries essential information about system behavior and confirmation. It could be tightened slightly, but given the complexity of the confirmation protocol and the need to prevent misuse, the length is justified.

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

Completeness5/5

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

The tool has only one parameter, no output schema, and the description covers all necessary information: what the tool does, when to use it, the confirmation flow, and the absence of network calls. Nothing critical is missing for correct invocation.

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

Parameters5/5

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

Schema coverage is 100%, but the description adds crucial semantics for confirmToken: it explains when to use it (two-step fallback), when not to use it (never on first call, never invented), and the lifecycle (passed back after user approval). This goes beyond just 'only for confirmation' to cover the exact protocol.

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?

The description clearly states the specific resource (locally stored Kia session/remember-me token) and the action (discard). It also differentiates from siblings by stating the only alternative (manual file deletion) and the recovery context (token revoked, password changed).

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

Usage Guidelines5/5

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

Explicitly describes when to use this tool (when stored token no longer works due to revocation, password change, or device change) and what it does NOT do (makes no network call, Kia is not told). It also mentions the alternative (manual file deletion) and the confirmation flow, providing clear usage context.

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