What is the core principle of this skill?

The core principle is to never fix just where the error appears; instead, trace backward until the source is found and fix it there while adding validation at every layer.

When should I use Root Cause Tracing instead of regular debugging?

Use it when an error occurs deep in execution, the stack trace is long, or the origin of invalid data is unclear and not located at the entry point.

Can I use Root Cause Tracing as a standalone skill?

Yes, while it is a sub-skill of systematic-debugging, you can invoke it directly if you are certain the bug is a deep-stack issue requiring call-chain tracing.

How does this skill handle test pollution?

It utilizes a bisection methodology and scripts like find-polluter.sh to run tests individually and identify exactly which execution causes the side effect.

Security & Testing

Systematically traces bugs from the point of failure back to the original trigger through call-chain analysis and instrumentation.

Root Cause Tracing is a specialized debugging skill designed to solve complex software errors that manifest deep within a call stack. Rather than patching symptoms where they occur, this skill enforces a backward-tracing methodology to find the true origin of invalid data or state. It provides structured guidance on adding instrumentation, analyzing stack traces, and using bisection scripts to identify test pollution. By identifying the source of an issue, developers can implement defense-in-depth validations that make the bug impossible to replicate, ensuring higher code quality and system stability.
