Use when scheduling a Hermes cron job or writing a watchdog script: recurring schedules need 'every 30m' (bare '30m' is ONE-SHOT — check repeat), no_agent+script shape, silent-unless-action stdout discipline, version-gated rollout watchdogs (marker files, surgical port-kill), idempotent ticks, and verifying CLI verb paths before the rollout branch can run.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cron / watchdog job authoring Class of work: recurring automation that acts when a condition flips (tool version released, PR changed, disk threshold crossed) and stays silent otherwise. Proven shapes for recurring deployments (tool rollouts, PR monitors). ## Pitfall: schedule strings — "30m" is ONE-SHOT `cronjob(action=create, schedule="30m")` produces **"once in 30m", repeat=once** — a single run. Recurring requires the literal prefix: `schedule="every 30m"`, `"every 2h"`, or a cron expression (`"0 9 * * *"`). After creating a job, CHECK the returned `schedule`/`repeat` fields and fix with `cronjob(action=update)` when they say `once`. (Measured 2026-08-07: created "30m", got one-shot; updated to "every 30m".) ## The watchdog pattern (no_agent + script) For deterministic jobs, skip the LLM: `no_agent=true` with `script=<name>` (resolves under `~/.hermes/scripts/`; `.sh`/`.bash` run via bash, everything else via Python). - **Silent unless action**: empty stdout = silent tick (no delivery); non-empty stdout is delivered verbatim; non-zero exit sends an error alert. Design the script to print ONLY when it took real action; write diagnostics to a log file …

How to install
mdr add arasz/ai-badger/cron-watchdog-authoring@sha256:53300655ecefdfaeThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
