Module: PWN::Cron

Defined in:
lib/pwn/cron.rb

Overview

PWN::Cron provides cron / scheduled task management for the pwn-ai agent. Jobs are defined in ~/.pwn/cron/jobs.yml and can be triggered by system cron, manual run, or from within pwn-ai agent loops.

Each job can contain a prompt (for pwn-ai), a ruby script snippet, or reference to external script. Delivery can be 'log' (default), 'email', etc. (email would require additional plugins).

Supported Method Parameters

PWN::Cron.install_defaults

Idempotently seed the RL feedback-loop cron jobs so a fresh install closes the loop by default (S1 practice + P3 offline_judge + W2 train dry-run + M1 consolidate). Re-running is a no-op if jobs with these names already exist. These are seeded to jobs.yml only — pass install_crontab: true to PWN::Cron.create yourself if you also want a system crontab entry. Hygiene jobs are enabled. Curriculum self-play / judge / LoRA are seeded disabled: practice runs Loop.run (real tools) overnight; offline_judge spends API tokens; train needs a GPU trainer.

DEFAULT_INTERVAL =

In-process scheduler. System crontab is optional (install_crontab) and install_defaults never writes it, so last_run only moves when something ticks jobs.yml. The worker is that something: poll once or loop, fire due enabled jobs via PWN::Cron.run, and stay alive behind a pidfile so pwn setup can start / restart it.

Spawned workers honor PWN_CRON_DIR so tests can sandbox the daemon without touching the operator's real ~/.pwn/cron.

WORKER_LOG = 
File.join(CRON_DIR, 'worker.log')
SYSTEMD_WORKER_UNIT =

OS-agnostic native persistence. jobs.yml remains the source of truth (5-field cron + relative "every 30m"). The in-process worker evaluates due? and fires jobs. A native backend only (a) restarts that worker after reboot / login and (b) optionally plants a calendar trigger per 5-field job so the schedule still fires if the worker is down.

linux -> systemd --user (Restart=always) else crontab @reboot osx -> launchd LaunchAgent (RunAtLoad + KeepAlive) windows -> schtasks ONLOGON *bsd / cygwin -> crontab @reboot when crontab(1) exists else -> in-process worker only (lives with the login)
