# 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 ```python 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) ```
