Foreign function interfaces: the C ABI as the boundary, repr(C) layouts, who allocates and who frees, strings and UTF-8 across the boundary, errors without unwinding, panics caught at the edge, callbacks and user data, thread safety, bindgen, cbindgen and cxx, bindings for Python, Node and WebAssembly, ABI versioning, and testing both sides. Read before calling across languages or exposing a library to another language.

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/'systems-ffi' ] || [ -L ~/.agents/skills/'systems-ffi' ]; then echo 'A skill folder named systems-ffi already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/enowdev/enowxcli' "$d" && git -C "$d" checkout --quiet '38293fe1b096e6bf3646c7344c38786ed688f464' -- 'crates/enowx-core/skills/systems-ffi' && mkdir -p ~/.agents/skills && cp -R "$d"/'crates/enowx-core/skills/systems-ffi' ~/.agents/skills/'systems-ffi' && 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/'systems-ffi' ~/.claude/skills/'systems-ffi' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
