About this plugin
If you work inside the official DeepSeek Harness (DSH) Web UI and also want access to Codex reasoning and tool-calling, you have historically had to switch between two separate interfaces or maintain a custom DSH fork. relay-dsh-plugin-codex embeds Codex as a native conversation backend directly in the official DSH Web UI, so you keep DSH workspace management, conversation history, composer, and approval flows intact while gaining Codex models and tools in a single window.
The plugin bundles a cross-platform Codex App Server runtime covering macOS, Windows, and Linux on x64 and arm64, so no global codex executable is required on your PATH. Each DSH Session is bound one-to-one to a Codex App Server Thread and supports model selection, reasoning-effort tuning, streaming responses with visible reasoning, live output from long-running shell commands, image input, interruption and continuation, as well as DSH native approval and user-question interaction patterns. Existing Codex sessions can be imported into a chosen workspace with a single action, preserving titles, activity order, and full turn history so you can immediately continue chatting.
This plugin is ideal for developers who want to bring Codex capabilities into their existing DSH workflow without changing the interface or maintaining a fork, and for teams that need a unified interface across multiple model backends. It installs independently, does not replace the DSH native layout, carries no runtime dependency on the Relay application or its event system, and does not add file-browsing or terminal-panel views.
