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/'devil' ] || [ -L ~/.agents/skills/'devil' ]; then echo 'A skill folder named devil already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/davila7/claude-code-templates' "$d" && git -C "$d" checkout --quiet 'a6e6f93e9a4baaa6ff337aee5505bf5c2bae4ce6' -- 'cli-tool/components/skills/productivity/devil' && mkdir -p ~/.agents/skills && cp -R "$d"/'cli-tool/components/skills/productivity/devil' ~/.agents/skills/'devil' && rm -rf "$d"; fi

For Claude Code: ln -s ~/.agents/skills/'devil' ~/.claude/skills/'devil' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
