root-cause
100 / 100 · Low risk
Fine to try.
Read-only root-cause analysis for any bug, test failure, or unexpected behavior — before proposing or writing any fix. Produces a brief with the root cause, files to change, approach, and risks. No edits, no commits, no state-changing commands. Use before /fix or /conductor whenever the cause isn't already proven. If static reading can't reach a confident cause, it hands off to /debugging-difficult-bugs for runtime instrumentation.
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/'root-cause' ] || [ -L ~/.agents/skills/'root-cause' ]; then echo 'A skill folder named root-cause already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/crbnos/carbon' "$d" && git -C "$d" checkout --quiet '23320e4132e2b978e186521fbfb4225017a18d1f' -- '.claude/skills/root-cause' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/root-cause' ~/.agents/skills/'root-cause' && 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/'root-cause' ~/.claude/skills/'root-cause' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
