Four bash tools that make cron jobs and agent loops boring. jobrun: flock no-overlap, timeout -k hard limit, retries with backoff + jitter, timestamped capped logs, per-job state + JSON, silent on success so cron only mails failures, alerts once on fail + on recovery. jobwatch: a watchdog that heals stale jobs and hung loops (heartbeats), rate-limits heals and gives up after 3 so a bad fix can't loop. jobstatus: OK/FAIL/RUNNING table. jobbeat: heartbeat for long-running agents. Alert hooks for ntfy, webhooks, Nostr DM (nak) and mail; crontab, systemd timer and agent-loop examples.

What's in the zip: README.md, LICENSE (MIT), the code, examples and a test script. Tested: 32 offline checks (exit codes, silence, alert rate limit + recovery, timeout, SIGKILL of TERM-ignoring jobs, retries, overlap, log cap, JSON, watchdog heal/rate-limit/give-up/recovery, heartbeats, bad config, stdin-safety). All pass from a fresh unzip on Debian, 2026-10-20.

Price: 2,000 sats. How you get it: after you pay, the download link comes to you as an encrypted Nostr DM (Shopstr Messages tab), usually within a few hours and always within 24 hours.
