**I wanted Claude Code to keep grinding while I sleep. So I built Night Shift 🌙**

It's a skill that turns a normal Claude Code session into an autonomous overnight dev agent.

**The idea:** give it one objective, walk away, and Claude Code keeps grinding for up to 8 hours. Wake up to work that's already planned, committed, tested, and reviewed.

**Under the hood it runs on an OKR loop.** You set the objective, Claude proposes key results, decomposes each into tasks, and ships them as individual commits on a feature branch. So the work stays scoped to what you actually asked for, not some 4am refactor spree.

**The other trick:** I didn't want one LLM grading its own homework (that's how you wake up to confidently broken code). **So Claude writes, Codex adversarially reviews every key result, every plan, every commit.** Neither one can call the shift done alone, they have to agree.

Never pushes, never touches main. In the morning you read the handoff doc and decide what ships.

Been having a lot of fun with it. Would love feedback if you try it.

I made a skill that can let Claude Code run 24 / 7 😆
