About this plugin
The default DeepSeek Harness Web composer is quite limited: fixed send and newline keys, no customizable right-click menu, repeated prompts must be retyped, and OpenCode routes can fail without a stable session header. dsh-composer-ux bundles these quality of life fixes into one client plugin so users do not need to edit host settings or handcraft patches just to make daily chat input feel better.
Its core features include configurable send and newline keys, a collapsible settings panel, a seven item right click menu, a categorized quick prompt panel, prompt optimization through a separate model call, and automatic x-opencode-session header injection for OpenCode requests. It also preserves the official send pipeline and IME safety, so queues, duplicate prevention, and menu triggers keep working as expected.
It is a good fit for users who chat in DSH Web frequently, especially developers who rely on custom keys, reusable prompts, quick editing, or stable OpenCode routing with cache friendly behavior.
Use Cases
- Remap send and newline keys to match your typing habit
- Insert frequently used prompts with one click from the quick-command panel
- Automatically attach the x-opencode-session header so OpenCode routes work inside DSH
Best For
- Developers who rely heavily on the DSH Web composer
- Individuals or teams managing large collections of prompt templates
- Users calling OpenCode endpoints through DSH
