Taskdone Runner: background tasks with completion notifications

Start a long command, close its terminal, and find its outcome later. Taskdone Runner keeps task IDs, working directories, logs, exit results, and an unread completion list for people and coding agents running parallel workflows. A normal Python process waits for each command. No LLM calls, model polling, service account, or hosted backend.

Useful for long scripts, batch jobs, and non-interactive coding-agent commands that otherwise finish unnoticed in another window. Process completion is not a quality review: exit code 0 means only that the command exited successfully.

# Python 3.10+ on macOS or Linux; install from this repository (not PyPI).
python3 -m pip install --user git+https://github.com/DeepCogNeural/taskdone-runner.git
# If your Python blocks user installs, use pipx instead (see below).
taskdone start -- sh -c 'sleep 3; echo "Result ready"'
# Copy the returned 32-character id:
taskdone list --unread
taskdone status TASK_ID
taskdone logs TASK_ID
# Inspect the actual output before marking it reviewed:
taskdone ack TASK_ID

Status: early alpha. The macOS integration suite and installed CLI have been exercised, including a real notification observed in Notification Center. macOS is the primary target; the implementation uses POSIX process sessions and file locks. Linux has file/terminal outcomes but no native notification adapter. Windows is unsupported.

If this helps, consider starring the repository.

Install, upgrade, and uninstall

There are no third-party runtime dependencies. Git-based installation needs Git and a packaging frontend. Build installation uses setuptools.

pipx install git+https://github.com/DeepCogNeural/taskdone-runner.git
# Later, after all running tasks finish:
pipx upgrade taskdone-runner
pipx uninstall taskdone-runner

Alternatively clone and run python3 taskdone.py --help directly, or install in a virtual environment with python3 -m pip install .. For a user-pip installation, uninstall with python3 -m pip uninstall taskdone-runner. Ensure the Python scripts directory is on PATH if taskdone is not found.

Uninstalling does not delete task history. Before removing an installation, replacing its Python environment, or deleting its checkout, wait for active tasks to finish. Afterward you may manually delete the selected state directory if you no longer need its logs. Taskdone has no remote service or login to revoke.

Commands and structured output

Global options precede the subcommand. taskdone --help and taskdone SUBCOMMAND --help describe the complete CLI.

Command	Purpose
start [--cwd DIR] [--result PATH] [--notify auto|off] -- COMMAND ...	Launch a detached command and return its record
list [--unread]	Read history and discover missing supervisors
status ID	Read task status, notification outcome, and artifact/log locations
logs ID [--bytes N]	Read the last N bytes of combined output (default 16 KiB; max 1 MiB)
ack ID	Record that a terminal task was reviewed

--json emits one JSON object. Task records include schema_version: 1, id, status, command, cwd, timestamps, process IDs, exit_code, reason, log_path, record_path, result_path, notification, reviewed_at, and needs_review. list wraps records in tasks; logs returns text, truncated, and log_path. Consumers should ignore unknown fields. Valid parsed commands return 0 when the CLI operation completes and 2 on an operation error ({"schema_version":1,"error":"..."} in JSON mode). Argument parsing errors use argparse's stderr and exit 2; help is plain text. The CLI exit code is not the task exit code. Read status and exit_code.

taskdone --json start --cwd "$PWD" --result report.txt -- sh -c 'printf "done\n" > report.txt'
taskdone --json list --unread
taskdone --json status TASK_ID
taskdone --json logs TASK_ID --bytes 32768

--result records an expected artifact path relative to --cwd; it does not create, validate, upload, or open that artifact. record_path points to the runner's own terminal outcome JSON, distinct from your artifact. Commands are argument arrays, with no implicit shell expansion. Use sh -c explicitly for pipes, redirects, or compound commands. stdin is /dev/null; interactive prompts, password entry, and TTY-dependent programs are unsuitable. Concurrent tasks are independent and have no queue or concurrency limit. Each uses one sleeping supervisor plus the resources consumed by its own command.

Lifecycle and recovery

State	Meaning
queued	Record created; supervisor has not recorded command startup
running	Supervisor holds its task lease and has launched the direct command
succeeded	Direct command exited 0; output quality remains unchecked
failed	Nonzero exit or command/supervisor launch failure; see raw reason/log
interrupted	Command exited from a signal, or supervisor received SIGINT/SIGTERM
lost	Supervisor ownership disappeared or internal supervision failed; outcome unknown

The launcher detaches its supervisor into a new POSIX session with file-backed stdout/stderr. The supervisor detaches the command and blocks in wait(); there is no resident model or polling agent. Closing an ordinary terminal does not send its session's hangup to these processes. OS logout policies, containers, IDEs that kill all descendants, shutdown, or explicit process termination may still kill them. Sleep pauses execution; this is not a keep-awake tool.

History is stored under ~/.local/state/taskdone, or TASKDONE_HOME / --home DIR. Keep it on a local filesystem with POSIX file locking. Records use atomic replacement and flushed file contents; this is not a power-loss-proof transactional database. Do not edit active records or share the directory across untrusted users or machines. Corrupt/unreadable records produce an explicit CLI error and need manual inspection; they are not silently discarded.

status and list reconcile a missing supervisor lease after a 15-second startup grace period, persist lost, and attempt its notification. No PID-reuse guess is used to establish supervision. After reboot, run list --unread to discover unfinished records; commands are not resumed or retried. There is no separate always-on service to notify while the computer is off or after a supervisor is forcibly killed. A lost command could still be running: inspect it before any manual retry. There is intentionally no PID-based automatic kill command.

Only the direct command is awaited. Commands that fork into the background or daemonize can outlive it; keep your workload in the foreground or make your own shell wait for all children. SIGTERM/SIGINT to the supervisor is forwarded to the command's process group, but a command can ignore signals or escape that group. There is no forced termination timeout. A live but stuck supervisor is not classified as lost.

All terminal states stay in list --unread until ack. This is a lightweight review marker, not proof of correctness or approval. Taskdone never performs a semantic review or automatically reruns a failed or paid command.

Notifications and troubleshooting

On macOS, auto invokes the system /usr/bin/osascript notification mechanism once per terminal transition. Permit the responsible application in System Settings → Notifications, and check Focus / Do Not Disturb if no banner appears. The sender shown by macOS can depend on the execution context. No permission settings are changed by Taskdone.

Notification status	What is known
pending	No attempt yet
attempting	Attempt intent persisted; crash during this window leaves delivery unknown
submitted	osascript returned 0; visible delivery is unconfirmed
failed	Adapter error or timeout; detail retained
unsupported	No system adapter on this platform
disabled	Started with --notify off

Attempt intent is saved before calling macOS. Reopening the CLI does not retry an attempted notification. This avoids duplicates at the cost of possibly missing a banner if the supervisor crashes during that window. A crash after saving a terminal result but before beginning notification can leave pending; there is no automatic replay. The durable result and unread list are the fallback. status displays the actual recorded attempt outcome; terminal commands do not receive unsolicited output in a closed window.

For a failed task, inspect reason, exit_code, output.log, and supervisor.log in its task directory. Check the executable, working directory, PATH, permissions, and whether the command expects interactive input. A blank log may reflect command buffering. Disk full or filesystem errors can prevent record persistence and notification: free space and inspect existing records. Taskdone does not infer quota exhaustion from exit codes. If an agent reports rate limits or exhausted credits, it must cite explicit original log evidence; otherwise the cause is unknown. The runner retains the raw log without parsing or replacing the command's failure explanation.

Privacy and boundaries

Commands inherit the launcher's environment, but the runner does not serialize that environment. Command arguments and working directories are stored. Avoid secrets in arguments. Commands may print credentials or private data; logs are raw, unredacted, unbounded, and retained until manually removed. Use a trusted private state directory and monitor disk usage. Newly created task folders/files are owner-only. Command children inherit that restrictive umask, so output files may have more restrictive permissions than in your terminal.

Taskdone never uploads task data. It is not a sandbox: the command has your local permissions and can access the network or spend money if you authorize such a command. Notification text contains only the short task ID and state, not your command or output. Treat log contents as untrusted data, not instructions.

For coding agents and contributors

See AGENTS.md for a short operational workflow: discover the CLI, start real commands, save IDs, retrieve artifacts, handle exceptions, and stop. Report bugs with a minimal redacted command, platform/Python version, status, and relevant log excerpt. Never post credentials or full private task history. The project is MIT licensed; no analytics, promotion automation, or star actions are included.

Tests

Run python3 -m unittest discover -s tests -v from the checkout. The standard library suite creates isolated temporary state and harmless child commands; it does not call models or paid services. Notification error paths use mocks. A real macOS notification requires a separate manual smoke check.

See TESTING.md for the exercised scenarios and remaining limits.
