Use this skill when the user wants to author, design, scope, or refine an Agent Skill (a SKILL.md file). Trigger phrases include "build a new skill", "design an agent skill", "scope a SKILL.md", "how should I structure this skill", "write a skill for X", "my skill isn't working well", or any request to improve an existing SKILL.md. Walks the user through an empirical, test-first process — probe the agent for real failures, design only for genuine knowledge gaps, iterate against runnable example…

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/'agent-skill-author' ] || [ -L ~/.agents/skills/'agent-skill-author' ]; then echo 'A skill folder named agent-skill-author already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/matlab/agent-skills-playground' "$d" && git -C "$d" checkout --quiet 'f93265a6477ea05028927530f02cd1e847c73d7e' -- 'demos/engineering-an-agent-skill/skills/agent-skill-author' && mkdir -p ~/.agents/skills && cp -R "$d"/'demos/engineering-an-agent-skill/skills/agent-skill-author' ~/.agents/skills/'agent-skill-author' && 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/'agent-skill-author' ~/.claude/skills/'agent-skill-author' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
