What problem does it solve? Long unattended coding runs often stall because the agent asks questions at startup or stops early. This Skill starts a Nightshift shift directly from the punch list the owner already prepared, so scheduled, headless, and interactive runs all begin the same way without human input. ## Core Features & Use Cases - Silent preflight: Runs a single preflight command that prints one verdict per line (ok, warn, refuse) and arms the shift only when every check passes. - Punch-list driven work: Treats the existing punch list as the shift contract, parking permission gaps instead of asking, and only offering staged drafts or work orders when the list is empty. - Session binding and recovery: Creates the armed marker, binds the session with a lease probe, verifies Codex task identity, and arms a watchman that revives crashed sessions. - Use Case: Schedule a cron job at 04:00 that invokes this Skill so Claude Code, Codex, or Cursor begins working through the punch list overnight and leaves receipts for morning review. ## Quick Start Ask the agent to start the Nightshift shift from the current punch list in this project.
