Safe Cron Runner 🛡️

A secure background task executor for AI Agents.

Overview

This skill wraps background task execution to ensure that autonomous agents don't accidentally (or maliciously) execute long-running or privileged commands.

Key Protections

1. Privilege Dropping: Automatically drops root privileges (switches to nobody) before executing the subprocess. 2. Strict Timeouts: Enforces hard timeouts to prevent infinite loops or resource exhaustion. 3. Shell Injection Protection: Uses list-based command execution (subprocess without shell) to prevent common command injection attacks. 4. Transparent Logging: Separates and logs stdout, stderr, and execution status for auditability.

ISNAD Signed

This skill includes an ISNAD manifest (isnad_manifest.json) verifying the integrity of the release.

Usage

from safe_cron import SafeCronRunner
runner = SafeCronRunner(safe_user="nobody", timeout_sec=60)
Execute command as a list for safety
result = runner.run_task(["ls", "-la", "/tmp"])
print(result)
