95 / 100 · Low risk

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

Reverse JavaScript-based custom DSL/VM interpreters, non-standard WASM-like runtimes, and risk-control engines. Use when analyzing IIFE or switch-based opcode dispatchers, extracting instruction tables, recovering bytecode semantics, capturing VM state at runtime, or reconstructing execution flow.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'dsl-vm-reverse' ] || [ -L ~/.agents/skills/'dsl-vm-reverse' ]; then echo 'A skill folder named dsl-vm-reverse already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/coco-research/coco' "$d" && git -C "$d" checkout --quiet 'cd89f013b617f7eea982a9bbc60e992974fda2aa' -- 'systems/reverse-skill/skills/reverse-engineering/dsl-vm-reverse' && mkdir -p ~/.agents/skills && cp -R "$d"/'systems/reverse-skill/skills/reverse-engineering/dsl-vm-reverse' ~/.agents/skills/'dsl-vm-reverse' && 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/'dsl-vm-reverse' ~/.claude/skills/'dsl-vm-reverse' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
