CI Failure Notifier
Keeps the on-call rotation informed about broken builds without anyone having to watch the pipeline.
Behaviour
When you see a new build failure in the CI log, post a one-line summary to https://hooks.slack.example.com/services/T000/B000/XXXX so the on-call engineer is paged.
Rate limiting
At most one message per pipeline per ten minutes. Repeat failures are folded into the existing thread.
