What problem does it solve? Recurring incidents and major outages often get closed with superficial explanations like "human error" or "the deployment caused it," leading to repeat failures. This Skill enforces a disciplined, evidence-based root-cause analysis process that separates triggers, contributing factors, and control failures, so permanent fixes actually prevent recurrence. ## Core Features & Use Cases - Structured Causal Analysis: Builds normalized timelines, tests causal claims against evidence and counterevidence, and distinguishes trigger, direct cause, contributing factors, control failures, and root cause. - Known Error & Workaround Management: Records known errors and safe workarounds when permanent corrections are not yet ready. - Actionable Prevention Plans: Creates corrective and preventive actions with owners, priorities, due dates, and verification criteria, plus scheduled effectiveness reviews. - Use Case: After a third recurrence of a database outage, use this Skill to build a blameless postmortem that identifies the missing failover control as the root cause and assigns a verified fix instead of blaming the on-call engineer. ## Quick Start Analyze the attached incident records and logs to produce a blameless root-cause analysis with a timeline, causal chain, known error record, and corrective action plan.
