dsh-codex-oauth

🔐 DSH-Codex-OAuth

English | 简体中文

🎯 What it does: Sign in with a ChatGPT / Codex subscription to enjoy powerful GPT models, image generation, and web search in DeepSeek Harness, with subscription quota reporting included.
🧩 Compatibility: Verified on DSH 0.1.0-rc.6; future releases will continue to be tested against the latest DSH version.
⚠️ Risk: This project is built on open-source software and relies on non-public ChatGPT Codex backend endpoints. OpenAI protocol changes may temporarily break features until the plugin is updated, and there may also be a low risk of account suspension.

✨ Plugin highlights

• 🚀 Direct subscription access — GPT models, image generation, and web search share your OpenAI subscription quota.
• 🧩 Controlled integration — the model picker, generated images, and web search integrate into DeepSeek Harness with dedicated controls.
• 🔐 Multiple sign-in methods — supports browser sign-in and headless device-code authorization.
• 🌗 UI adaptation — follows DSH's English/Chinese language and Light, Dark, or System theme.

Example Cordis configuration:

- insert:
    - id: dsh-codex-oauth
      name: "@wnjxyk/dsh-codex-oauth"
      config:
        dshHome: /data/dsh
        path: /secure/codex-oauth.json
        preferencesPath: /secure/codex-oauth-preferences.json
        issuer: https://auth.openai.com
        usageUrl: https://chatgpt.com/backend-api/wham/usage

      name: "@wnjxyk/dsh-codex-oauth/web-search"
      config:
        model: gpt-5.6-sol

Web search and image-generation orchestration both default to the Codex Power model gpt-5.6-sol; images are rendered by the hosted GPT Image (image_generation) tool; chat models are discovered dynamically from the openai-codex model provider supplied by DSH's built-in llm-pi-ai plugin.
