codex-plusplus Tweak System

Skill by ara.so — Daily 2026 Skills collection.

codex-plusplus is a tweak injection system for the Codex desktop app (Electron-based). It patches app.asar, injects a loader stub, and runs a hot-reloadable runtime from the user directory. Tweaks are small ESM modules with a manifest and start/stop lifecycle — no app rebuild required.

Installation

Homebrew (macOS, recommended)

brew install b-nnett/codex-plusplus/codexplusplus
codexplusplus install
