## Overview & Purpose

starter-root-cause-investigation is a starter workflow that chains skills together. It chains together the ideal combination of reasoning skills for high-level tasks, without needing manual setup.

## Execution Workflow

1. **Execute 5-Whys Traversal (`causal-analysis`)**: Map symptoms back to fundamental root causes using counterfactual testing.
2. **Empirical Hypothesis Testing (`scientific-method`)**: create falsifiable hypotheses, design experiments, and record findings.
3. **Simulate Dynamic Behavior (`simulation-reasoning`)**: Model system behavior over time under seed conditions to observe emergent failures.
4. **Self-Audit Reasoning (`metacognitive-monitoring`)**: Perform real-time bias detection to ensure conclusions are grounded strictly in evidence.
