Use a ChatGPT/Codex subscription in DeepSeek Harness with GPT models, image generation, web search, subscription quota reporting, model and feature controls, and browser or device-code OAuth sign-in.
Install
# from npm (prebuilt)
dsh plugin --profile web add @wnjxyk/dsh-codex-oauth
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:WNJXYK/dsh-codex-oauth
Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time. Only install sources you trust, and pin a commit (github:owner/repo#sha).
README
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.
