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 real banner, native cards, and project selector.
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.
• 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.
