Set Up Dex

If System/.onboarding-complete already exists, setup is complete. Use getting-started for the post-onboarding tour or reset for a role or preference change.

One narrow existing-vault repair is allowed: if setup is complete but System/.dex/harness-profile.json is missing or Doctor says agent harness capabilities are OFF, do not restart onboarding. Call inspect_harnesses, show the automatic / on-demand / guided / unavailable preview and each host's named limits, ask the person to confirm one or more harnesses, then call save_harness_selection(..., confirmed=true). That tool writes only the harness receipt through the sanctioned provision transaction and leaves the profile, content and onboarding marker unchanged.

Otherwise:

1. Call start_onboarding_session() from onboarding-mcp to initialize or resume the session.
2. Read core/onboarding/FLOW.md and follow it as the single source of the onboarding conversation.

This file deliberately contains no question script, so onboarding cannot fork. Change onboarding in core/onboarding/FLOW.md and onboarding-mcp, then regenerate the byte-identical .claude/flows/onboarding.md compatibility copy; never fork the question script here.
