Codex OAuth connector

Project overview

Connect your ChatGPT subscription to DeepSeek Harness with OAuth, user-controlled defaults, Harness-native approvals, diagnostics, and reliable session recovery.

dsh-codex-connect adds the openai-codex model catalog and a separate ChatGPT OAuth login. Models run through Harness's normal LLM service, so streaming, tool calls, reasoning replay, compaction, filesystem controls, permission gates, and approval prompts remain Harness-owned. It does not turn a ChatGPT subscription into an OpenAI Platform API credential.

Sign in and manage the plugin from Settings → Plugins → Plugin configuration → Codex Connect.
