Fine to try.
Interactive root cause analysis facilitator — runs a structured 5-Why why chain session, challenges each answer with evidence requirements, detects symptomatic and circular reasoning, and produces a validated Why chain with reversal check. Use for 8D D4, CAPA investigations, FMEA cause analysis, or any quality investigation requiring confirmed root cause identification.
What this skill can do
We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'rca-facilitator' ] || [ -L ~/.agents/skills/'rca-facilitator' ]; then echo 'A skill folder named rca-facilitator already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '70b6a3a3a7c774671e45af646306e1448baf0511' -- 'plugins/RBraga01/Quality-Engineering-Skills/skills/agents/rca-facilitator' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/RBraga01/Quality-Engineering-Skills/skills/agents/rca-facilitator' ~/.agents/skills/'rca-facilitator' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'rca-facilitator' ~/.claude/skills/'rca-facilitator' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
