Orchestrate complete Root Cause and Corrective Action (RCCA) investigations using the 8D methodology. Guides team formation (D1) with domain-specific recommendations, problem definition (D2), containment (D3), root cause analysis (D4) with integrated tool selection (5 Whys, Fishbone, Pareto, Kepner-Tregoe, FTA), corrective action (D5-D6), prevention (D7), and closure (D8). Use when conducting RCCA, 8D, root cause analysis, corrective action, failure investigation, nonconformance analysis, quality problems, or customer complaints.
Fuzzing skill for automated input-driven bug finding in C/C++. Use when setting up libFuzzer or AFL++ fuzz targets, defining fuzz entry points around parsing or I/O boundaries, integrating fuzzing into CI, managing corpora, or combining fuzzing with sanitizers.
