Silent Fail
Checks whether your automation actually did the work, not just that it ran.
Silent Fail catches a failure mode normal monitors miss: an agent or workflow that finishes, reports success, and leaves the wrong data behind — like an invoice duplicated at half its real total. The free tier pings a URL at the end of your workflow and emails you if it stops arriving. The paid Supervision tier has you describe a good run in plain English, approve the checks a model compiles from that, then runs those checks inside your own process on every run and emails you by name when one fails — only a pass/fail verdict is ever sent back, never your data.
What holds up
- +Catches 'ran fine but wrong result' failures, like a duplicated invoice, that leave every monitor green.
- +Checks run inside your own process and send back only a pass or fail — never your data.
- +You approve the exact checks in plain English before anything is ever judged by them.
- +Free tier covers 3 monitors with no code — just one URL pinged at the end of a workflow.
Mind the limits
- −Catching wrong-data failures needs a few lines of SDK code — the free ping alone won't catch it.
- −One check (judging if a summary is fair) is still answered by a model, not pure arithmetic.
