What this is

You already pay for Claude Code or ChatGPT. That subscription sits idle most of the day, and definitely all night. nightaudit spends that idle time reviewing the projects you point it at, and leaves the results in one Markdown file you read with your coffee.

Either CLI works — Claude Code or Codex, whichever you have. Have both and it uses both, each with its own budget.

It never edits your code. It has no daemon and no server — cron calls it, it decides whether to run, and it goes back to sleep. Everything it knows lives in two directories you can delete at any time.

That's the whole tool. Everything below is how to start; the docs are the detail.

Features

• Read-only, and not on the honour system. Enforced by the AI CLI's own permission layer — an allowlist Claude Code applies, or the kernel sandbox Codex runs under. A bug in the model cannot touch the disk.
• Uses the subscription you already pay for. No API key. It drives the same claude or codex you use by hand, on your own plan.
• Budget-aware. Hard caps per day and per week, per provider, counted in a ledger it keeps itself.
• Stays out of your way. It only runs inside the hours you choose, and only once you've been away from the CLI long enough.
• Multi-project. Add repos one path at a time, or point --discover at a folder and it finds every git repo under it. A round-robin queue means a noisy repo can't starve the rest.
• One digest a morning. Every finding ranked by severity with a file:line, in a single Markdown file — with how many tokens each project's reviews took.
• No daemon, no server. Cron calls it, it decides whether to run, it exits. Everything it knows lives in two directories you can delete.

Installation

pipx install nightshift-cli
nightaudit --version

That is not a typo: the tool is nightaudit everywhere except the install line. It was published as nightshift-cli before the rename, and PyPI has no way to rename a project without stranding everyone on the old one. You type it once.

Getting Started

nightaudit init                 # find your CLIs, pick projects and hours, write cron
nightaudit init --discover ~/code   # or scan a folder and pick from what it finds
nightaudit run --now            # don't wait until tonight
nightaudit status               # budget, next window, what's up next

init asks for a project path and gives everything else a working default — or type scan <folder> at the prompt (or pass --discover) to add every git repo under a folder from a checklist. Then cron takes over: it runs in the hours you chose, once you've been away long enough, until the budget says stop.

Development

python -m venv .venv && .venv/bin/pip install -e ".[dev]"
.venv/bin/pytest

The test suite spends zero quota: the scheduler, budget, queue, and digest are covered against a FakeAdapter, and the Claude Code adapter is tested with a mocked subprocess. No test ever shells out to a real AI CLI.

The images on this page are generated from real captured output — see docs/RECORDING.md if you change what the CLI prints.
