Investigates and resolves software bugs through hypothesis-driven reproduction and evidence-based fixes.
The Debug skill transforms Claude into a methodical troubleshooting partner that follows a rigorous investigation process to solve complex software issues. Rather than guessing, it focuses on reproducing the problem, forming weighted hypotheses, and gathering evidence using tools like Playwright for frontend issues and Bash for backend failures. It operates as a standalone utility, making it an essential tool for identifying root causes and verifying fixes through a structured workflow that ensures code stability and prevents regressions.
