dsh-tui: A Terminal Workbench Interface for DeepSeek Harness

What Does It Do?

DSH TUI is a DSH plugin for DeepSeek Harness that turns the command line into a full terminal workbench built on the native DSH kernel and pi-tui, with layered messages, a file-edit pane, permission presets and hot-swappable themes. It solves the problem of hard-to-review context and tool output, hard-to-resume sessions and opaque interface state in a plain CLI. Maintained by ArcaneOrion and written in JavaScript, the repository was created on 2026-10-01.

Core Features

• Layered messages and full-text panels: tool previews stay short while complete arguments, raw results and structured data open through /inspect or Ctrl+O, with scrolling, paging and jump-to-start/end inside the panel.
• File-edit pane: a diff appears on the right while Edit/Write runs and the last state is kept after the turn; /pane cycles auto, on and off, and narrow terminals collapse it automatically.
• Permissions and presets: a persistent permission hint sits below the status line and cycles with Shift+Tab, turning to a warning color at the dangerous level; /preset offers standard, ptc, minimal and cordis, switchable only in kernel-approved blank sessions.
• Hot-swappable themes: /theme opens a picker or switches directly between the blue and pi palettes, taking effect immediately and being remembered.
• Session resume and queue: /resume searches past sessions and restores them in place across the current or all workspaces, while /queue shows and withdraws unprocessed input.
• Extensible UI service: the active interface is published as a Cordis service that can set status, header, footer, editor, widgets and per-role message renderers.

How to Use This Plugin?

After enabling it in DSH, launch the terminal interface to start a conversation, optionally with an initial task, a specific model or a preset. Inside the interface, use Ctrl+K or /workbench to search and pick a working view, /context to inspect the current model context and its sources, /inject to add context for the next step without waking the agent, and /steer for the nearest next-step intervention. Use /resume to search and restore a past session in place, finishing the current turn or draining the queue first. With no model configured, a demo mode still lets you explore the workbench, full tool output, context and message queue using fixed fictional data, without calling a model or running file tools.

How to Troubleshoot This Plugin?

The interface ships a /doctor command for real service-connection diagnostics, which is the first place to look when services fail to attach. If /resume feels slow, the status bar shows that the session directory is being read, and reopening the same scope within 20 seconds uses a cache; setting DSH_TUI_DEBUG_SESSIONS=1 writes both timing segments to a log file in the temporary directory. If a restore fails, the current session is kept, so finish any running turn or subagent and drain the queue before retrying.
