## Overview & Purpose

starter-code-debugging 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. **Isolate Error Boundary (`debugging-approach`)**: Use binary search troubleshooting to isolate the root failure line or component.
2. **Execute Code Dry-Run (`code-execution-reasoning`)**: Perform line-by-line mental execution tracking variable states and pointer references.
3. **Iterative Refinement (`sequential-thinking`)**: Step through code logic, revising hypotheses as new evidence is revealed.
4. **Stress-Test & Red-Team Fix (`pdr-reasoning`)**: Predict edge cases, attempt to break the solution, and harden against regressions.
