Cron Worker Guardrails (POSIX)

A reliability-first checklist for OpenClaw cron workers and any unattended automation.

Scope (important)

• This skill is POSIX-focused (bash/sh examples).
• The principles are portable, but if you're on Windows/PowerShell you'll need equivalent patterns.

The NO_REPLY convention

Many OpenClaw setups treat emitting exactly NO_REPLY as "silent success" (no human notification).

• If your runtime does not support NO_REPLY, interpret it as: print nothing on success.
