Klaviyo Incident Runbook

Overview

Rapid incident response for Klaviyo API outages and integration failures: quick triage, decision trees, mitigation steps, and postmortem templates. Use this skill to move from "Klaviyo is broken" to a classified severity, an applied mitigation, and a written postmortem — without improvising under pressure.

The heavy content (full triage script, per-error remediation blocks, and the communication + postmortem templates) lives in references/ so this file stays a fast high-level runbook you can follow end-to-end, then drill into for depth.
