Code Documentation Code Explain

When you're staring at unfamiliar code or trying to onboard someone into a gnarly codebase, this skill breaks down what's actually happening through narratives, diagrams, and progressive walkthroughs. It focuses on high-level flow first, then drills into complexity hotspots with annotated snippets and visual aids. Good for explaining algorithms, design patterns, or system architectures when plain API docs won't cut it. The output explicitly calls out edge cases and pitfalls, which is honestly what you need when debugging something you didn't write. Not meant for generating new code or refactoring, just pure explanation and analysis.
