Core Debugging & Diagnostics

About

The Core Debugging skill provides a structured framework for Claude to perform deep-dive investigations into software bugs, performance regressions, and unexpected system behaviors. By separating the diagnostic phase from the implementation phase, it ensures that developers identify the true root cause of an issue rather than just patching symptoms. This skill employs professional techniques such as hypothesis-driven debugging, binary search, git bisecting, and strategic instrumentation to provide a comprehensive understanding of complex problems across the entire stack.

Key Features
