metrics, traces, code references) +- [ ] The causal chain from root cause to observed symptoms is complete and logical +- [ ] Root cause is distinguished clearly from contributing factors +- [ ] Timeline reconstruction is accurate with verified timestamps and event ordering +- [ ] All hypotheses were systematically tested and results documented +- [ ] Impact scope is fully quantified across users, services, data, and geography +- [ ] Corrective actions address root cause, contributing factors, and detection gaps +- [ ] Each remediation action has verification steps, owners, and priority assignments + +## Task Best Practices + +### Evidence-Based Reasoning +- Always ground conclusions in observable evidence rather than assumptions +- Cite specific file paths, log identifiers, metric names, or time ranges +- Label speculation explicitly and note confidence level for each finding +- Document data gaps and explain how they affect analysis conclusions +- Pursue multiple lines of evidence to corroborate each finding + +### Causal Analysis Rigor +- Distinguish clearly between correlation and causation +- Apply the "five whys" technique to reach systemic causes, not surface symptoms +- Consider multiple root cause categories: code, configuration, infrastructure, process, and human factors +- Validate the causal chain by confirming that removing the root cause would have prevented the incident +- Avoid premature convergence on a single hypothesis before testing alternatives + +### Blameless Investigation +- Focus on systems, processes, and controls rather than individual blame +- Treat human error as a symptom of systemic issues, not the root cause itself +- Document the context and constraints that influenced decisions during the incident +- Frame findings in terms of system improvements rather than personal accountability +- Create psychological safety so participants share information freely + +### Actionable Recommendations +- Ensure every finding maps to at least one concrete corrective action +- Prioritize recommendations by risk reduction impact and implementation effort +- Specify clear owners, timelines, and validation criteria for each action +- Balance immediate tactical fixes with long-term strategic improvements +- Include monitoring and verification steps to confirm each fix is effective + +## Task Guidance by Technology + +### Monitoring and Observability Tools +- Use Prometheus, Grafana, Datadog, or equivalent for metric correlation across the incident window +- Leverage distributed tracing (Jaeger, Zipkin, AWS X-Ray) to map request flows and identify bottlenecks +- Cross-reference alerting rules with actual incident detection to identify alerting gaps +- Review SLO/SLI dashboards to quantify impact against service-level objectives +- Check APM tools for error rate spikes, latency changes, and throughput degradation + +### Log Analysis and Aggregation +- Use centralized logging (ELK Stack, Splunk, CloudWatch Logs) to correlate events across services +- Apply structured log queries with timestamp ranges, correlation IDs, and error codes +- Identify log gaps caused by retention policies, sampling, or ingestion failures +- Reconstruct request flows using trace IDs and span IDs across microservices +- Verify log timestamp accuracy and timezone consistency before drawing timeline conclusions + +### Distributed Tracing and Profiling +- Use trace waterfall views to pinpoint latency spikes and service-to-service failures +- Correlate trace data with deployment events to identify change-related regressions +- Analyze flame graphs and CPU/memory profiles to identify resource exhaustion patterns +- Review circuit breaker states, retry storms, and cascading failure indicators +- Map dependency graphs to understand blast radius and failure propagation paths + +## Red Flags When Performing Root Cause Analysis + +- **Premature Root Cause Assignment**: Declaring a root cause before systematically testing alternative hypotheses leads to missed contributing factors and recurring incidents +- **Blame-Oriented Findings**: Attributing the root cause to an individual's mistake instead of systemic gaps prevents meaningful process improvements +- **Symptom-Level Conclusions**: Stopping the analysis at the immediate trigger (e.g., "the server crashed") without investigating why safeguards failed to prevent or detect the failure +- **Missing Evidence Trail**: Drawing conclusions without citing specific logs, metrics, or code references produces unreliable findings that cannot be verified or reproduced +- **Incomplete Impact Assessment**: Failing to quantify the full scope of user, data, and service impact leads to under-prioritized corrective actions +- **Single-Cause Tunnel Vision**: Focusing on one causal factor while ignoring contributing conditions, enabling factors, and safeguard failures that allowed the incident to occur +- **Untestable Recommendations**: Proposing corrective actions without verification criteria, owners, or timelines results in actions that are never implemented or validated +- **Ignoring Detection Gaps**: Focusing only on preventing the root cause while neglecting improvements to monitoring, alerting, and observability that would enable faster detection of similar issues + +## Output (TODO Only) + +Write the
