loop-task

loop-task

A cross-platform CLI that repeatedly executes a shell command at a human-readable interval.

Inspired by agent loops, but intentionally simple.

Installation

npm install -g loop-task

Or use directly with npx:

npx loop-task 30m npm test

Usage

loop-task [options] <interval> <command>

Basic examples

loop-task 30m npm test
loop-task 1h opencode --prompt '/ob-init'
loop-task 1d node sync.js

With npx

npx loop-task 30m npm test
npx loop-task 1h opencode --prompt '/ob-init'

Options

Options must come before the interval:

Option	Description
--immediate	Run immediately before waiting
--max-runs <n>	Stop after N executions
--verbose	Show execution details
-h, --help	Display help
-V, --version	Display version

Examples

Agent workflows

npx loop-task 30m opencode --prompt "search for missing translation text and translate them, 3 maximum" --model "opencode/big-pickle"

Run tests every 30 minutes

loop-task 30m npm test

Run immediately, then every hour

loop-task --immediate 1h npm test

Run up to 5 times then stop

loop-task --max-runs 5 5m npm test

Verbose mode

loop-task --verbose 30m npm test

Shows start/end timestamps, exit code, execution duration, and next scheduled run.

Supported intervals

Format	Description
10s	10 seconds
5m	5 minutes
1h	1 hour
1d	1 day
1w	1 week

Behavior

• No overlapping: waits for the command to finish before starting the next interval
• Resilient: continues looping even if a command exits with a non-zero code
• Graceful shutdown: finishes current execution on Ctrl+C, then exits cleanly

Development

pnpm install
pnpm run build
pnpm run test
pnpm run lint
