XJTU Codex Theme

Custom XJTU theme for Codex Desktop

GitHub

01 / Context

Why It Exists

Codex Desktop's default theme is generic with limited personalization. As a Xi'an Jiaotong University user, I wanted a theme that reflects campus cultural identity while maintaining readability and professionalism.

Problem

Codex Desktop has limited theme customization; manual modifications easily break compatibility. Light and dark mode adaptation requires separate handling, and theme switching may cause style anomalies.

Solution

XJTU Codex Theme provides preset light and dark theme schemes, injecting via brief local Node Inspector pulses without modifying WindowsApps, app.asar, Codex config, browser profiles, or login credentials. Supports compatibility checking, verification, and fail-safe recovery. No restart required for switching.

02 / System

Core Capabilities

  • XJTU Academic Theme, Codex Skin Maker, Unbranded Template
  • Injection via brief local Node Inspector pulses
  • Does not modify WindowsApps, app.asar, Codex config, browser profiles, or login credentials
  • Compatibility checking, verification, and fail-safe recovery
  • No restart required for switching

03 / Workflow

Workflow

  1. Download or clone theme files
  2. Run theme installation script
  3. Select light or dark mode
  4. Node Inspector pulse injection takes effect
  5. Verify theme application results

04 / Boundaries

Security & Privacy

Security boundary: binds only to local Inspector port, target PID verification, verify/disable, reconfirmation before preview. Does not touch login state or conversation content. Does not modify WindowsApps, app.asar, Codex config, browser profiles, or login credentials.

Current Limitations

  • Only supports Windows 10/11 x64, Microsoft Store version of Codex Desktop
  • Depends on Codex Desktop Electron internal structure; may need adaptation after updates
  • Requires Node.js 22+
  • Unofficial experimental project, not affiliated with OpenAI or Xi'an Jiaotong University
