devils-twin
100 / 100 · Low risk
Fine to try.
The strongest possible case AGAINST what you just wrote — argued to win, not to check a box. Use when a document is about to ship and everyone around it already agrees: the twin writes the opposition's best memo (not a critique of yours), so you meet the real counter-argument before your audience does. Produces the opposing memo, the map of which of your claims it defeats/dents/leaves standing, and the pre-emption paragraph worth adding.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'devils-twin' ] || [ -L ~/.agents/skills/'devils-twin' ]; then echo 'A skill folder named devils-twin already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mohitagw15856/pm-claude-skills' "$d" && git -C "$d" checkout --quiet 'edb6995427bac9d948775258a82aeecced60ceb1' -- 'skills/devils-twin' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/devils-twin' ~/.agents/skills/'devils-twin' && 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/'devils-twin' ~/.claude/skills/'devils-twin' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
