# agent-queue
A zero-dependency **folder "kanban" runner** for headless coding-agent CLIs —
**Devin**, **Claude Code**, and **OpenAI Codex**. Drop prompt `.md` files into a folder,
and they get executed (in auto-approve mode) one slot at a time, moving through
`inbox → building → review → testing → shipped` (plus `failed`) with live status.
**Build/ship lifecycle — auto-QA, manual ship:**
```
inbox ─▶ building ─▶ review ─▶ testing ─▶ shipped
(queued) (agent (rc=0; (verify (you ran
running) awaiting passed — `ship`)
verify) QA gate)
│
agent rc≠0 / │ verify fails
timeout ──────────┴──────────────▶ failed
```
- **Auto:** agent exits 0 → `review/`. If a `verify:` command is configured it runs
automatically: **pass → `testing/` (QA)**, **fail → `failed/`**. No `verify:` →
the job parks in `review/` for a manual `promote`.
- **Manual:** you `ship` a `testing/` job → `shipped/` (the human gate). Shipping is
never automatic.
> **Why this exists:** the agent CLIs ship a minimal local interface (no built-in
> batch/queue/dashboard — that lives in their *cloud* products). This is the
> zero-dependency bash glue that turns "run one prompt interactively" into
> "queue many and walk away."

## Quick start
```bash
cd learning_ai_devops_tools/agent-queue
chmod +x agent-queue.sh
./agent-queue.sh init
# queue a roadmap for Devin, running in the tracker-web repo, auto-approving everything
./agent-queue.sh add ~/roadmaps/UX-2.md \
--engine devin \
--cwd /Users/sd9235/code/mygh/learning_ai_common_plat/dashboards/tracker-web \
--yolo
# start processing (foreground; Ctrl-C to stop). Run up to 3 agents at once (default).
./agent-queue.sh run --max 3
```
In a **second terminal**, watch progress:
```bash
./agent-queue.sh watch
```
```

## How a task is configured
Each `.md` carries optional **frontmatter** telling the runner which engine to use,
which directory to run in, and whether to auto-approve:
```md
---
engine: devin # devin | claude | codex (default: $AGENT_QUEUE_ENGINE)
cwd: /abs/path/to/repo # where the agent executes (default: cwd when added)
yolo: true # auto-approve ALL tools (default: true)
lock: my-repo # optional mutex key (default: cwd). Jobs sharing a key run serially
timeout: 45m # optional. 90s|45m|2h|1d. On expiry → failed (result=timeout)
verify: pnpm -s test # optional auto-QA gate. Runs in cwd after rc=0:
# pass → testing/ (QA), fail → failed/
# (omit to park in review/ for manual promote)
---
# Your task / roadmap goes here
...
```
`add --engine/--cwd/--yolo` will inject this frontmatter for you if the file doesn't
already have a `---` block.
## Engine mapping
| `engine:` | Command run | Auto-approve flag (`yolo: true`) |
| --------- | ----------- | -------------------------------- |
| `devin` | `devin -p --prompt-file
` | `--permission-mode dangerous` |
| `claude` | `claude -p` (body on **stdin**) | `--dangerously-skip-permissions` |
| `codex` | `codex exec` (body on **stdin**) | `--dangerously-bypass-approvals-and-sandbox` |
The frontmatter is **stripped** before the body reaches the agent, and
claude/codex receive it on **stdin** so a body starting with `--` is never
misparsed as a flag.
> Flags drift between CLI versions — if one changes, edit `build_agent_cmd()` in
> `agent-queue.sh` (it's the single place each engine is mapped).
## Commands
| Command | What it does |
| ------- | ------------ |
| `init` | create the `queue/` folders |
| `add [--engine E] [--cwd P] [--yolo\|--no-yolo]` | queue a prompt into `inbox/` |
| `run [--max N] [--engine E] [--once]` | process the inbox (foreground loop) |
| `status` | kanban counts + running-worker table (marks `⚠ stalled` workers) |
| `watch [interval]` | live `status` (bash), redrawn every N seconds (default 2) |
| `dash [--interval N]` | **interactive Node dashboard** — navigable numbered job list with single-key actions (see below) |
| `stop` | kill running workers + the run loop |
| `logs [-f]` | print / follow a job's log |
| `promote ` | advance one stage forward: `review → testing → shipped` |
| `ship ` | **manual gate:** move a `testing/` (QA) job → `shipped/` |
| `reject ` | send a `review/` or `testing/` job → `failed/` |
| `requeue ` | move a `failed`/`review`/`testing` job back to `inbox/` for a fresh run |
| `clean [--keep N]` | archive finished logs+meta beyond the newest N (default 50) into `queue/.archive/` |
Only one `run` loop may be active per queue — a second `run` against the same
queue is refused while the first is alive (a stale `daemon.pid` is cleared).
### Interactive dashboard (`dash`)
`dash` is a single-script, menu-driven control panel (think a tiny "glassbox").
It shows the kanban counts, live RUNNING workers (engine, elapsed, last log
line, stall), a **navigable numbered JOBS list**, and RECENT finished jobs — and
lets you act on jobs without leaving the screen. Every action shells out to
`agent-queue.sh`, so the script stays the single source of truth.
| Key | Action |
| --- | ------ |
| `↑`/`↓`, `j`/`k`, `1`–`9` | select a job in the JOBS list |
| `enter` / `l` | view the selected job's log (live, auto-refreshing) |
| `p` | promote (`review → testing → shipped`) |
| `s` | ship (`testing`/QA → `shipped`, the manual gate) |
| `x` | reject (`review`/`testing` → `failed`) — asks `y/n` |
| `u` | requeue (`failed`/`review`/`testing` → `inbox`) — asks `y/n` |
| `r` | start the `run` loop (detached → `logs/run-loop.log`) |
| `S` | stop the run loop + running workers |
| `g` | refresh now · `?`/`h` help · `q`/`Ctrl-C` quit |
The header shows a `● run loop pid N` / `○ run loop stopped` indicator. Run it in
a TTY for the interactive mode; piped/non-TTY it falls back to a read-only live view.
## Via `bytelyst-cli.sh`
Wired into the repo's unified CLI (no GitHub token required for this subcommand):
```bash
./bytelyst-cli.sh agent-queue run --max 3 # full passthrough
./bytelyst-cli.sh aq status # short alias
```
## Folder layout
```
queue/
inbox/ # drop / queued .md files (oldest eligible picked first)
building/ # currently executing (agent running)
review/ # agent exited 0 — awaiting the auto-QA verify gate (or manual promote)
testing/ # verify passed (QA) — awaiting manual `ship`
shipped/ # manually shipped — the terminal success stage
failed/ # non-zero exit, bad cwd, timeout, verify failure, or manual reject
logs/ # .log — full agent + verify output
locks/ # per-key flock files (Linux hardening; unused on macOS)
.state/ # .meta heartbeats + daemon.pid (runtime only)
.archive/ # / — logs+meta moved here by `clean`
```
**`result=` values** written to `.meta`: `review`, `testing`, `shipped`,
`failed`, `timeout`, `verify_failed`, `rejected`, `requeued`.
## Config (env overrides)
| Var | Default | Meaning |
| --- | ------- | ------- |
| `AGENT_QUEUE_ROOT` | `./queue` | where the kanban folders live |
| `AGENT_QUEUE_MAX` | `3` | max concurrent agents (override per-run with `run --max N`) |
| `AGENT_QUEUE_ENGINE` | `devin` | default engine when none in frontmatter |
| `AGENT_QUEUE_POLL` | `3` | inbox poll interval (seconds) |
| `AGENT_QUEUE_VERIFY` | _(empty)_ | default auto-QA verify command; per-job `verify:` overrides it |
| `AGENT_QUEUE_STALL_MIN` | `10` | minutes of unchanged log before a worker is `⚠ stalled` |
| `DEVIN_BIN` / `CLAUDE_BIN` / `CODEX_BIN` | autodetected | override CLI binary paths |
| `FLOCK_BIN` / `TIMEOUT_BIN` | autodetected | `flock` (lock hardening) and `timeout`/`gtimeout` (hard timeouts); absent on stock macOS — see notes |
## ⚠️ Safety
Running agents with `yolo: true` means **no approval prompts** — they will edit files,
run shell commands, and commit unattended. Mitigate:
- Prefer **scope-locked** prompt files (e.g. "edit only under `dashboards/tracker-web/`").
- Tell prompts **not to `git push`** — review commits before they leave your machine.
- **Same-repo safety is automatic:** jobs sharing a `cwd` (or `lock:` key) are
serialized, so two agents never run in one repo at once — even at `--max 2+`.
- Set a `timeout:` on long jobs so a wedged agent can't run forever.
- Watch cost: each job is a full agent session.
### Portability notes
- **macOS** has no `flock`/`timeout`; locking relies on the single run-loop
(enforced by the second-run refusal) and timeouts use a pure-bash watchdog.
Install coreutils (`gtimeout`) for hard process-tree kills.
- **Linux** (incl. Gitea CI) uses `flock` + `timeout` for cross-process hardening.
## Roadmap / nice-to-haves
- [x] Per-repo lock to serialize same-repo jobs automatically (`lock:` / cwd).
- [x] Per-job `timeout:` with hard kill (or bash watchdog fallback).
- [x] Stall detection in `status`/`dash`.
- [x] `requeue` failed jobs + `clean`/archive old runs.
- [x] Build/ship lifecycle: `review → testing → shipped` with auto-QA `verify:` gate + manual `ship`.
- [ ] `--push` opt-in policy + commit review gate.
- [ ] Optional notifications (Slack/desktop) on done/failed/stall.
- [ ] Persisted run-loop as a daemon/service with auto-restart.
