    Classical root cause analysis techniques for quality improvement and incident investigation. Covers 5 Whys (with Card's 2017 critique and boundary conditions), Ishikawa/fishbone diagrams, Fault Tree Analysis (FTA), Failure Modes and Effects Analysis (FMEA), Cause Mapping, and Doggett's method-selection framework. Use when investigating a failure, running a post-incident analysis, building a fishbone, calculating fault tree cut sets, running an FMEA pass, or deciding which classical technique fits the problem. Not suitable alone for complex socio-technical failures — escalate to rca-systems-theoretic or rca-causal-inference when the incident has multiple interacting causal chains.

    Rca Systems Theoretic · majiayu000 bundle

    Systems-theoretic approaches to root cause analysis for complex socio-technical systems where linear causal chains fail. Covers Nancy Leveson's STAMP (Systems-Theoretic Accident Model and Process), STPA (System-Theoretic Process Analysis) for hazard analysis, CAST (Causal Analysis based on STAMP) for post-incident investigation, Rasmussen's risk-management framework and dynamic safety model, Hollnagel's FRAM (Functional Resonance Analysis Method), and AcciMap. Use when investigating incidents in healthcare, aviation, nuclear, autonomous systems, distributed microservices, or any system where multiple actors and control loops interact — especially when classical RCA produces a "list of human errors" that leaves the underlying system design unchanged.

    Spec Driven Analytics · majiayu000 bundle

    Orchestrate session data mining operations through a 7-phase workflow with structural anti-skip enforcement. Analyzes Claude Code history.jsonl files and workflow artifacts to deliver formatted, actionable analytics for workflow patterns, errors, decisions, and command sequences. Prevents token optimization bias through per-phase reference loading, checkpoint persistence, Execute-Verify-Record enforcement, and artifact verification. Use when analyzing session data, extracting workflow patterns, investigating error trends, or reviewing development decisions. Always use this skill when the user runs /analytics or mentions session analytics, workflow patterns, error mining, decision archive, or command sequence analysis.
