Audit a skill by running a paired probe — the same task once with the skill loaded and once without — segment both traces into goal-directed phases, align phases, and emit a SIP report (surface anchoring, template copy, excess planning, task recovery, off-task artifact). Use whenever a skill is created, modified, or proposed for retirement. Pass-rate is BLIND to most skill effects: CTA (arxiv 2605.11946v1) shows a single skill can produce 522 measurable behavioural changes across 49 tasks while…

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/'skill-counterfactual-audit' ] || [ -L ~/.agents/skills/'skill-counterfactual-audit' ]; then echo 'A skill folder named skill-counterfactual-audit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Tibsfox/gsd-skill-creator' "$d" && git -C "$d" checkout --quiet 'e179dfe911f3b3c2ff8bcd90ecd6ee4738648d17' -- 'project-claude/skills/skill-counterfactual-audit' && mkdir -p ~/.agents/skills && cp -R "$d"/'project-claude/skills/skill-counterfactual-audit' ~/.agents/skills/'skill-counterfactual-audit' && 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/'skill-counterfactual-audit' ~/.claude/skills/'skill-counterfactual-audit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
