# claude-overnight

**Queue research questions all day. Wake up to answers.**

![demo](assets/demo.gif)

Your Claude Code weekly limit quietly expires while you sleep — if you hit the 5-hour cap every day, you still leave weekly quota on the table every single night. `claude-overnight` puts that idle quota to work: queue questions with `/queue` during the day, and a scheduler runs them headlessly inside your configured night window, when your limits have reset. You wake up to a folder of markdown research reports and a morning digest.

```
you (2:14 pm) ──▶ /queue what are the tradeoffs of CRDTs vs OT for a collab editor?
you (5:40 pm) ──▶ /queue compare litestream vs. postgres logical replication for a side project

              💤  3:00 am — limits reset, window open, batch runs

you (8:05 am) ──▶ ~/.overnight/results/index.md
                  ✅ tradeoffs of CRDTs vs OT — crdts-vs-ot.md
                  ✅ litestream vs postgres replication — litestream-vs-postgres.md
```

## Why

- **Limit-aware, not just time-aware.** Cron can run Claude at 3am, but it doesn't know whether your 5-hour window is fresh or your weekly cap is nearly gone. `claude-overnight` checks both before starting and *between every job*, and stops at a configurable threshold so you wake up with quota left for actual work.
- **Runs on your subscription, unattended.** Jobs execute through `claude -p` (headless mode) with tools restricted to web search — no API key, no extra cost.
- **Zero dependencies.** Pure Python standard library. `uv tool install claude-overnight` and you're done.

## Install

```sh
uv tool install claude-overnight   # or: pipx install claude-overnight
overnight install                  # sets up the scheduler + /queue slash command
```

`overnight install` does two things:

1. Registers a **scheduler** — a launchd agent on macOS, a systemd user timer on Linux — that wakes every 30 minutes, checks whether you're inside the night window and under the limit thresholds, and runs the queue if so.
2. Drops a **`/queue` slash command** into `~/.claude/commands/`, so you can queue questions without leaving Claude Code.

Requires macOS or Linux, Python 3.11+, and the [Claude Code](https://code.claude.com) CLI with a Pro/Max subscription. Also installable as a Claude Code plugin (`/plugin marketplace add rohanprichard/claude-overnight`) or an agent skill (`npx skills add rohanprichard/claude-overnight`).

## Use

```sh
# from anywhere
overnight add "how do sqlite WAL checkpoints actually work?"

# or inside any Claude Code session
/queue how do sqlite WAL checkpoints actually work?

overnight list          # see the queue
overnight status        # current 5h/weekly utilization + would-it-run-now
overnight results       # read the digest (or one report: overnight results <id>)
overnight resume <id>   # open an interactive claude session where the job left off
overnight run --dry-run # explain exactly what would happen and why
overnight run --force   # run the batch right now, ignoring window/limits
overnight retry         # requeue failed jobs
```

Per-job flags: `--model opus` to override the model, `--first` to jump the queue.

## Overnight coding jobs

Beyond research questions, you can queue actual work against a repo:

```sh
overnight trust ~/code/myapp              # one-time, per repo
overnight add --repo ~/code/myapp "add a dark mode toggle to settings; follow the existing theme pattern and run the tests"
```

Or from a Claude Code session inside the repo, just `/queue add a dark mode toggle...` — the command detects it's a coding task and captures the repo automatically.

Overnight, the job runs in a **fresh git worktree on a dedicated branch** — your working tree, uncommitted changes, and checked-out branch are never touched. In the morning:

```
git diff main..overnight/add-a-dark-mode-toggle-3f9c2a   # love it or delete it
```

The agent commits its work (WIP-prefixed if it got stuck), writes a `SUMMARY.md`, and the digest shows the branch plus a diffstat. Branches with no changes are dropped automatically.

**Safety model:** coding jobs run with `acceptEdits` (they need to edit files and run your tests), so they only run against repos you've explicitly blessed with `overnight trust`. The worktree fences file changes, but a job can execute shell commands — trust repos accordingly. Research jobs remain locked to web-search tools.

Results land in `~/.overnight/results/<date>/`, one markdown report per question, with a rolling `index.md` digest. A notification fires when the batch finishes.

**Every overnight job saves its Claude session.** `overnight resume <id>` (any unambiguous fragment of the id works) drops you into the conversation that produced the result — ask follow-ups, challenge conclusions, or redirect the work, with all of the overnight context already loaded. For coding jobs it recreates the worktree on the job's branch first, so "change the approach in this PR" just works.

## Configure

`~/.overnight/config.toml`:

```toml
[window]
start = "01:00"   # jobs only run between these local times
end = "07:00"     # windows may cross midnight ("23:00" → "06:00")

[limits]
start_max_utilization = 20   # don't start if the 5h window is already >20% used
stop_utilization = 60        # stop the batch once 5h usage crosses 60%
weekly_max_utilization = 80  # never run if the weekly limit is >80% used

[run]
model = "sonnet"
job_timeout_minutes = 15       # research jobs
repo_job_timeout_minutes = 45  # coding jobs get time to build and test
max_attempts = 2
```

## How it works (there's no official API)

Claude Code doesn't expose a usage API — but it stores an OAuth token locally (macOS Keychain / `~/.claude/.credentials.json`), and the community discovered that `GET https://api.anthropic.com/api/oauth/usage` with that token returns your 5-hour and weekly utilization with reset timestamps. `claude-overnight` uses that to decide when it's safe to run.

Because the endpoint is **undocumented and could change**, everything degrades gracefully: if usage can't be read, the runner proceeds optimistically and detects limit errors from `claude -p` output instead — a job that hits the limit is requeued untouched for the next window, and the batch stops.

Full details in [docs/how-it-works.md](docs/how-it-works.md).

## Edge cases handled

- **Machine asleep at 3am** — launchd (and systemd with `Persistent=true`) runs the missed tick on wake, so the batch runs when you open the lid, still before you start working.
- **One job eating the whole window** — per-job timeouts plus utilization re-checks between jobs.
- **Two runners racing** — lockfile with stale-lock recovery.
- **Headless Claude wanting to ask you something** — the prompt template instructs it to make reasonable assumptions and state them.
- **Weekly cap already blown** — the runner skips the batch and says why in `overnight status`.

## Uninstall

```sh
overnight uninstall            # removes the scheduler + slash command
uv tool uninstall claude-overnight
rm -rf ~/.overnight            # queue, results, config
```

## Roadmap

- Follow-up jobs: `overnight followup <id> "go deeper on X"` — queue a continuation of a saved session for the next window
- `--after <date>` job scheduling hints ("research this before Monday")
- "Quota saved this week" stats in `overnight status`
- Digest delivery to Telegram/ntfy/email
- Pluggable backends: the queue, scheduler, and threshold logic are agent-agnostic — only the `claude -p` invocation and the limits reader are Claude-specific. Codex (`codex exec`) and Cursor CLI backends are on the table if there's demand.
