dsh-tui

DeepSeek Harness has always kept its control surface in a browser tab: switching models, managing sessions, reshuffling workspaces—all of it meant leaving the editor to click through Chrome. dsh-tui brings that entire control plane into the terminal. It ships as a self-contained npm package that layers terminal Host services over dsh-base via cordis.patch.yml, without touching the Harness source tree. At startup it connects to the Web Host already listening on 127.0.0.1:3080, sharing the workspace registry and event stream; when that address is unreachable it silently falls back to an in-process API client so a workstation can run the full workflow standalone.

The interaction layer rides on pi-tui's alternate-screen renderer and differential update pipeline. Sessions, models, providers, workspaces, skills, subagents, settings, credentials, goals, and plugins each open native terminal panels driven by a fuzzy-searchable picker: type to filter, arrow keys to highlight, Enter to confirm. The composer supports Enter to send, Alt-Enter to steer the active turn, Escape to clear or cancel, and arrow keys to traverse input history. The @file mention token queries the Host's file-reference index in remote mode and silently falls back to local path completion in standalone mode. Multi-turn questions render as arrow-navigable menus with a free-text escape hatch, and a batch confirmation summary lets you reopen any individual answer before submitting. The visual theme follows VS Code Dark+: user messages as full-width background bubbles, reasoning in italic gray, code blocks with per-token syntax highlighting, and verbose context or tool output collapsed into a single-line header that peels open progressively with each keystroke.

It is built for developers who treat the terminal as their primary workspace-engineers living inside tmux splits or iTerm2 key bindings, and Harness power users who constantly juggle remote sessions, model routes, and workspace groupings. Once dsh-tui is in place, the browser tab becomes optional.
