version: "1.0.1" name: codex-dream-skin-studio description: Install, customize, launch, verify, repair, update, or restore Codex Dynamic Skin Studio on macOS.

Codex Dynamic 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 Dynamic Skin.command from the complete project folder.
2. Run Customize Codex Dynamic Skin.command, choose an image in Finder, and enter a theme name.
3. To add a complete downloaded pack, use the native menu's “导入主题 ZIP…”. Accept ordinary .zip only. Every new official Studio pack contains manifest.json, non-empty theme.json, non-empty locally validated theme.css, exactly one registered background, and optional license/signature files; the trusted local simplified format contains exactly theme.json, theme.css, and its referenced image. Import into saved themes without changing the active theme. A manually extracted complete three-file directory may instead be moved into the saved themes folder. Previously saved legacy themes without CSS remain switchable but inject no extra CSS.
4. Verify the live result with Verify Codex Dynamic 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.
5. Restore the official appearance with Restore Codex Dynamic 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.
• Theme-pack import does not support .dreamskin; reject traversal, links, nested archives, ambiguous roots, size/count abuse, and packs that fail the existing theme/image payload checks.
• 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.
