Author a new Dex skill that actually fires and passes the quality bar. Runs a collision check, classifies the shape, writes a router-grade description, generates the real package (SKILL.md + evals), and grades it with `skill-score` before calling it done. Use when the user says 'make a skill', 'I want a /command for X', 'turn this into a skill'. A skill the user builds for themselves is saved under `.claude/skills-custom/` (protected from updates) and coached, never blocked — ask for it by its …

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/'create-skill' ] || [ -L ~/.agents/skills/'create-skill' ]; then echo 'A skill folder named create-skill already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/davekilleen/Dex' "$d" && git -C "$d" checkout --quiet 'd759c3a0e91e617d1bd879dc449d6d61681b90fb' -- '.claude/skills/create-skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/create-skill' ~/.agents/skills/'create-skill' && 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/'create-skill' ~/.claude/skills/'create-skill' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
