100 / 100 · Low risk

Fine to try.

By TheStack-ai/swing-skills (GitHub) · coding · 41 stars · scanned at commit 3272dd8

Prospective failure analysis using Gary Klein's pre-mortem technique. Assumes complete failure, works backward to identify risks, leading indicators, and circuit breakers. Counters optimism bias by forcing systematic exploration of failure modes before they materialize. Use for project plans, architecture decisions, technology adoption, business strategy, or feature launches. Triggers on "리스크", "위험", "실패하면", "swing-mortem", "뭐가 잘못될 수 있어", "risk", "what could go wrong", "걱정되는 점", "failure modes"…

Works with any agent that supports SKILL.md skills.

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/'swing-mortem' ] || [ -L ~/.agents/skills/'swing-mortem' ]; then echo 'A skill folder named swing-mortem already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/TheStack-ai/swing-skills' "$d" && git -C "$d" checkout --quiet '3272dd89c85d646fe3b6162b9c869f19278cfd4c' -- 'skills/swing-mortem' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/swing-mortem' ~/.agents/skills/'swing-mortem' && 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/'swing-mortem' ~/.claude/skills/'swing-mortem' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
