dsh-codex-shim

In the DeepSeek Harness (DSH) framework, using GPT-family or Codex-adapted models can present challenges in tool interaction reliability and consistency. The dsh-codex-shim plugin addresses this by simulating Codex-style prompts, tool vocabulary, tool results, and WebUI presentation for selected model routes, enhancing the reliability of tool usage.

The core capability of this plugin lies in bridging DSH's existing features with Codex-style interaction patterns. It registers tools like command execution, patch application, image viewing, and plan updates, which become available on active Codex routes. When models match specific patterns or configurations, the plugin emulates Codex behavior, masking overlapping host tools to provide a more coherent tool-calling experience. It's important to note that this is not a full Codex runtime but focuses on leveraging DSH's public service definitions and UI slots.

This plugin is ideal for developers working within the DSH environment who use GPT-5.6 or other Codex-adapted models. If you seek more reliable tool interactions, especially in the WebUI, this plugin can help standardize model outputs and tool-calling workflows. It suits scenarios where you want a Codex-like experience without switching to the full Codex runtime.
