# Root Cause Analysis Skill ## Overview The Root Cause Analysis (RCA) skill provides structured methodologies and tools for conducting thorough root cause investigations for incidents and problems. This skill supports multiple analysis frameworks including 5-Whys, Fishbone/Ishikawa diagrams, and Fault Tree Analysis to identify underlying causes and drive permanent corrective actions. ## Capabilities ### 5-Whys Analysis - Facilitate structured 5-Whys questioning - Document causal chain progression - Identify stopping criteria for root causes - Generate 5-Whys analysis reports - Track branching cause paths - Validate root cause identification ### Fishbone/Ishikawa Diagrams - Generate fishbone diagram structures - Organize causes by category (6M model) - Support custom category definitions - Create visual diagram outputs (Mermaid, SVG) - Facilitate brainstorming sessions - Document contributing factors ### Fault Tree Analysis - Build fault tree logical structures - Define AND/OR gate relationships - Calculate probability propagation - Identify minimal cut sets - Generate fault tree visualizations - Support quantitative risk analysis ### Contributing Factor Identification - Analyze mul

Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
