VLM-authored skill creation. When the existing toolbox can't accomplish what you need, define a new helper function with Python code and register it. After register_skill returns ok=True the function is: - Available in the namespace of subsequent exec_python(code=...) calls (call it like any other base skill) - Persisted to the skill library; shows up in future trials' system prompt as a PROMOTED FUNCTION This is the CaP-X "skill library evolution" mechanism, but PROACTIVE — you decide when to …

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/'register-skill' ] || [ -L ~/.agents/skills/'register-skill' ]; then echo 'A skill folder named register-skill already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nssmd/RoboRSI' "$d" && git -C "$d" checkout --quiet '90c8569705bf4004a4f79e34e650c87ab7f075d4' -- 'roborsi/embodied/skills/base/register_skill/robotwin' && mkdir -p ~/.agents/skills && cp -R "$d"/'roborsi/embodied/skills/base/register_skill/robotwin' ~/.agents/skills/'register-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/'register-skill' ~/.claude/skills/'register-skill' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
