4x4

100 / 100 · Low risk

Fine to try.

By davidondrej/skills (GitHub) · other · 4,266 stars · scanned at commit c23d902

Pull 16 fast decisions out of the user with 4 sets of 4 open questions, then present an implementation plan. Only for risky changes, large product decisions, or large refactors. Run when the user types /4x4. Agents may suggest it in one line but never start it on their own.

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/'4x4' ] || [ -L ~/.agents/skills/'4x4' ]; then echo 'A skill folder named 4x4 already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/davidondrej/skills' "$d" && git -C "$d" checkout --quiet 'c23d9026faad2a122b989e6faf54930e099bc19e' -- 'skills/thinking-and-docs/4x4' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/thinking-and-docs/4x4' ~/.agents/skills/'4x4' && 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/'4x4' ~/.claude/skills/'4x4' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
