Incident Root Cause Synthesis and Resiliency Spec

Role: Staff Site Reliability Engineer specializing in distributed systems telemetry and post-incident retrospectives.

Context

• Incident Identifier: {{incident_id}}
• System Topology: {{service_topology}}
• Telemetry & Diagnostic Extracts: {{telemetry_extracts}}
• Chronological Event Log: {{incident_timeline}}
• Impacted Service Level Objectives: {{impacted_slos}}
• Remediation Team Lead: {{remediation_owner}}

Task

Synthesize raw telemetry, distributed traces, and team triage records into a comprehensive incident remediation and architectural hardening specification that prevents recurrence and stabilizes service reliability.

Method

1. Reconstruct the end-to-end failure propagation path across {{service_topology}} using {{telemetry_extracts}}.
2. Correlate timestamps from {{incident_timeline}} against telemetry anomalies to isolate the primary trigger versus secondary cascading failures.
3. Quantify the blast radius by mapping system degradation against {{impacted_slos}}.
4. Evaluate why existing observability mechanisms and automated alerts failed or experienced detection lag.
5. Categorize root contributing factors across code defects, concurrency bottlenecks, network partitions, and resource saturation.
6. Formulate precise architectural safeguards, including circuit breakers, retry backoffs, and rate-limiting rules.
7. Detail short-term containment tasks and structural long-term engineering work for {{remediation_owner}}.
8. Establish programmatic verification tests to validate that the failure state is reproducible and permanently mitigated.

Constraints

• MUST cite specific log events or metric anomalies from {{telemetry_extracts}} to substantiate every claim.
• MUST NOT assign human error as a root cause; focus strictly on system ergonomics, safety guardrails, and architectural vulnerabilities.
• Recommendations MUST be partitioned cleanly into immediate patch requirements and long-term architectural refactors.
• Limit architectural diagram proposals to text-based Mermaid format.

Output format

1. Executive Incident & Impact Summary (max 200 words)
2. Causal Chain & Failure Propagation Breakdown (ordered sequence)
3. Telemetry & Observability Gap Analysis
4. Technical Remediation Specification (Code-level & Infrastructure changes)
5. Automated Regression & Chaos Testing Verification Plan

Self-review

• Verify every root cause is backed by data from {{telemetry_extracts}} or {{incident_timeline}}.
• Check that all proposed mitigations map directly to an identified failure vector in {{service_topology}}.
• Ensure remediation work contains testable acceptance criteria for {{remediation_owner}}.
