dsh-web-terminal

The DeepSeek Harness web GUI is built for multi-turn conversation and tool orchestration, but the moment you need to operate the host shell directly from the browser—running top to check load, editing a config with vim, or triaging a process tree in htop—you have to leave the tab and hunt for a separate terminal. dsh-web-terminal closes that gap by mounting a Terminal entry onto the sidebar so your AI session and the host shell live in the same workspace.

The expanded panel is a multi-tab xterm.js experience. Every tab drives a real PTY shell session via node-pty, with input and output streamed over a WebSocket route. Interactive programs such as vim, top, and htop work as you would expect, including Ctrl-C and live window resize. The panel ships controls for opening a new tab, closing, disconnecting and reconnecting, and clearing output. The shell binary and working directory are configurable through the settings panel or a patch yaml file, and the view auto-fits its height on panel open, window resize, and container changes.

Security-wise, every route carries a loopback-only trust fence (same-origin plus 127.0.0.1/localhost checks). Commands execute with the host user's privileges, which is equivalent to direct shell access. The plugin is hot-pluggable through the standard dsh dual-face mount pattern and requires no source changes to dsh itself.

If you are a developer, SRE, or ops engineer who already works inside the DeepSeek Harness web interface daily, this plugin lets you chat, tail logs, and run interactive commands without ever leaving the browser tab.
