What problem does it solve?
This Skill helps diagnose runtime failures, stack traces, test breakages, and script exceptions by tracing the root cause and applying the smallest safe fix.
Core Features & Use Cases
- Structured Triage: Extracts key signals from errors, reproduces issues when possible, and asks for missing information when the report is incomplete.
- Root Cause Analysis: Reads the innermost stack frames first, follows the call chain upward, and classifies issues such as data, dependency, configuration, or logic faults.
- Minimal Repair and Verification: Applies targeted edits, scans for similar defects, and reruns commands or tests to confirm the fix without changing intended behavior.
- Use Case: A test suite starts failing after a code change; this Skill identifies the failing path, patches the bug with minimal edits, and verifies the regression is resolved.
Quick Start
Ask the debug skill to analyze the error message, identify the root cause, patch the minimal code change, and verify the fix.
