cron skillA

cron is agent-read markdown (skill) from bug-ops/zeph: Schedule recurring and one-time tasks using cron, crontab, at, and launchd. Use when the user asks to set up scheduled jobs, configure crontab entries, write cron expressions, schedule one-time tasks with at, create launchd plist files on macOS, debug why a cron job is not running, or manage periodic automated tasks on Unix/Linux/macOS systems..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add bug-ops/zeph/cron@v1.0
Exact content
mdr add bug-ops/zeph/cron@sha256:7be9f425ca0c185c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
