Show and tell: Codex Connect — ChatGPT OAuth and OpenAI Codex models for DSH

[franksong2702]

Codex Connect is a DSH plugin that connects a ChatGPT account to DeepSeek Harness through OAuth and exposes OpenAI Codex models through the normal Harness model path.

Repository: https://github.com/franksong2702/dsh-codex-connect
npm: https://www.npmjs.com/package/dsh-codex-connect
Latest prerelease: https://github.com/franksong2702/dsh-codex-connect/releases/tag/v0.1.0-alpha.4.4

What it provides

• Browser and device-code OAuth flows, with a separate owner-only credential store.
• OpenAI Codex models in the normal Harness model picker.
• Configuration under Settings → Plugins → Plugin configuration → Codex Connect.
• Opt-in Codex search and remote image tools; both are disabled by default.
• Additive installation: it does not replace the current default model or search provider.
• Harness-native sessions, tools, attachments, permissions, approvals, compaction, and recovery.
• Secret-free diagnostics, provider-conflict guidance, and migration documentation.
• Network boundary checks for remote images and hardened loopback-only browser OAuth routes.

Install

dsh plugin --profile web add dsh-codex-connect@alpha
dsh web

To pin Alpha 4.4 exactly, use dsh plugin --profile web add dsh-codex-connect@0.1.0-alpha.4.4. If npm is unavailable, use dsh plugin --profile web add 'github:franksong2702/dsh-codex-connect#v0.1.0-alpha.4.4'.\n\nThen open Settings → Plugins → Plugin configuration → Codex Connect and sign in. Installing the plugin does not automatically select it as the default model.\n\nAlpha 4.4 aligns the npm and documentation distribution paths: npm is now the primary installation entry, the package page renders the English root README, and exact-version/GitHub fallback guidance is included. Runtime behavior is unchanged from Alpha 4.3.\n\nThis is an Alpha release. ChatGPT plan eligibility, model availability, quotas, and backend behavior remain controlled by OpenAI. Please report reproducible issues in the repository.\n\n---\n\nCodex Connect 通过 OAuth 将 ChatGPT 账号与 OpenAI Codex 模型接入 DeepSeek Harness。安装是增量式的：不会自动替换当前默认模型或搜索提供方，搜索和远程图片能力也默认关闭。配置入口位于 设置 → 插件 → 插件配置 → Codex Connect。Alpha 4.4 已正式发布到 npm，首选安装命令为 dsh plugin --profile web add dsh-codex-connect@alpha；本次只对齐发布与文档入口，运行行为与 Alpha 4.3 相同。\n\n项目基于 Yan-Zero/dsh-codex 的工作继续开发，并保留上游归属；Codex Connect 的修改与新增工作由 Frank Song 维护，按 Apache-2.0 发布。本项目与 OpenAI、DeepSeek 或 DeepSeek Harness 不存在隶属或背书关系。
