Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

ALWAYS invoke this skill before anything hard to undo gets agreed to - a contract, a purchase, a migration, a launch, a price change, a reorganisation - and whenever the user asks "what could go wrong", "what are we missing", "poke holes in this", or for a premortem or a red team, in any language. Assumes the decision already failed and works backwards to find out why, in a fresh agent that had no hand in making it. Sweeps nine areas and shows what each produced, including the empty ones. Ends …

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'os-what-could-go-wrong' ] || [ -L ~/.agents/skills/'os-what-could-go-wrong' ]; then echo 'A skill folder named os-what-could-go-wrong already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/kharmanskyi/open-steps' "$d" && git -C "$d" checkout --quiet '4f4102704db28c9285d9ab4617769a8920e7cf86' -- 'skills/os-what-could-go-wrong' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/os-what-could-go-wrong' ~/.agents/skills/'os-what-could-go-wrong' && 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/'os-what-could-go-wrong' ~/.claude/skills/'os-what-could-go-wrong' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
