Set up a codebase so an AI agent can build it unattended for hours or days, safely and resumably. Use when planning a large refactor or overhaul, breaking work into agent-executable specs, configuring ZCode or Claude Code for long autonomous runs, connecting an agent IDE to a remote dev box over SSH, writing guardrail hooks, or when the user says "have it code while I sleep", "goal mode", "remote dev", "spec-driven", or "run the whole plan unattended".
