Codex Dream Skin Studio

Codex Dream Skin Studio

This file is an optional Codex capability entry. The delivery is a complete standalone project; users do not need to install it as a Skill.

Workflow

1. Run Install Codex Dream Skin.command from the complete project folder.
2. Run Customize Codex Dream Skin.command, choose an image in Finder, and enter a theme name.
3. Verify the live result with Verify Codex Dream Skin.command. A pass requires a visible native sidebar and composer, no horizontal overflow, non-interactive decoration, and—on the home route—a continuous wallpaper with live native heading, project controls, and any suggestion cards exposed by the current Codex version.
4. Restore the official appearance with Restore Codex Dream Skin.command.

Guardrails

• Never modify the official .app, app.asar, or its code signature.
• Use the official Codex app's signed Node.js runtime only after validating its signature, Team ID, architecture, and minimum version.
• Bind CDP to loopback, verify that the listener belongs to Codex, and reject non-Codex renderer targets.
• Preserve all native cards, navigation, project selectors, task content, composer controls, and keyboard focus.
• Theme images must be UI-free wallpapers. Paint one 16:9 image continuously across the window; keep home expressive and task routes quieter. appearance: auto follows Codex/native or system appearance rather than image brightness.
• Keep decoration at pointer-events: none.
• Require explicit authorization before restarting an already-running Codex instance.
• Stop an injector only when its recorded PID, executable, command line, and start time all match.
