Builds a DOM cursor trail in which short code fragments on brightly coloured bars stack into a leftward staircase that chases the pointer, each row easing toward the row above it, with an autonomous steering drift when nobody is pointing. Use when someone asks for a cursor trail, a code-themed hero, a pointer-following stack, a playful developer page header, or coloured tags that follow the mouse.

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/'code-trail' ] || [ -L ~/.agents/skills/'code-trail' ]; then echo 'A skill folder named code-trail already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/arla6ka/design.how' "$d" && git -C "$d" checkout --quiet '419fa5af1721eebfab9e0062a630de36ffd0b342' -- 'vault/code-trail/skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'vault/code-trail/skill' ~/.agents/skills/'code-trail' && 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/'code-trail' ~/.claude/skills/'code-trail' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
