Silent Fail
A dead-man's switch for scheduled workflows.
Silent Fail is a heartbeat monitor for scheduled automations and agents. Each monitor has a unique HTTP ping URL that resets a deadline clock; a missed ping triggers one email alert and one all-clear when pings resume. It also offers drift detection based on a monitor's own history, and a supervision feature where users describe in plain English what a successful run should leave behind, approve the compiled checks, and then each run is evaluated by deterministic code inside the user's own process via Python and TypeScript SDKs, with model-answered checks limited to named fields.
