VigilObservability & Reliability

Builds alerting rules grounded in SLOs with paired runbooks for every alert. Defines error budgets, creates alert conditions at the right thresholds to minimize false positives, and writes runbooks with investigation steps and specific remediation options so the on-call engineer knows exactly what to do when paged.

When to use
