Simon Willison shared about Claude Code plugins, and then specifically about Superpower, that has some accumulated tricks within.
Naturally, I was attracted to the example that was provided on Root Cause Tracing:
-------------------//---------------------
name: Root Cause Tracing
description: Systematically trace bugs backward through call stack to find original trigger
when_to_use: Bug appears deep in call stack but you need to find where it originates
version: 1.0.0
languages: all
Overview
Bugs often manifest deep in the call stack (git init in wrong directory, file created in wrong location, database opened with wrong path). Your instinct is to fix where the error appears, but that's treating a symptom.
Core principle: Trace backward through the call chain until you find the original trigger, then fix at the source.
