Nightshift: MIT-licensed plugin adds planning, evidence, and recovery to long-running coding agents

Details

Nightshift is a free, MIT-licensed plugin for Codex, Claude Code, and Cursor that manages long-running coding tasks through a persistent on-disk workflow.
The system separates planning from execution, keeping project code read-only during the planning phase to generate a punch list with specific checks and evidence requirements.
Execution supports two modes: finishing an agreed list or working toward a goal for a set time, with 30+ ready-made shifts available for tasks like security and performance.
Each task item generates a receipt updated every 20 minutes by default, recording progress, token usage, and evidence such as screenshots or test outputs.
A separate watchman process handles recovery from crashes or API outages, and the on-disk state allows users to stop work in one agent and resume in another.
