Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Darwin Skill (达尔文.skill): autonomous skill optimizer inspired by Karpathy's autoresearch. Evaluates SKILL.md files using an 8-dimension rubric (structure + effectiveness), runs hill-climbing with git version control, validates improvements through test prompts, and generates visual result cards. Use when user mentions "优化skill", "skill评分", "自动优化", "auto optimize", "skill质量检查", "达尔文", "darwin", "帮我改改skill", "skill怎么样", "提升skill质量", "skill review", "skill打分".

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'darwin-skill' ] || [ -L ~/.agents/skills/'darwin-skill' ]; then echo 'A skill folder named darwin-skill already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/IZRINO/delta-auto-tools' "$d" && git -C "$d" checkout --quiet '8fc3549df59e3960c80f5f16ba10f44de754a708' -- '.claude/skills/darwin-skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/darwin-skill' ~/.agents/skills/'darwin-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/'darwin-skill' ~/.claude/skills/'darwin-skill' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
