dsh-tui

DeepSeek Harness ships a web UI and a one-shot headless mode, but has never offered a true interactive terminal agent. dsh-tui fills that gap: it is not a model wrapper or a plain chat REPL, but a full-screen TUI that drives the real Harness agent runtime — file editing, shell execution, subagent delegation, plan mode, sessions, and permissions all work exactly as they do in the browser.

The experience is built for flow: answers stream token-by-token, reasoning blocks render in dim italics with per-turn effort control, and tool calls appear as boxed cards with lifecycle markers (running / done / error) plus argument and result previews. A complete slash-command suite covers session resume, live permission switching, conversation compaction, a trajectory event timeline, environment diagnostics, and model selection. Markdown rendering handles fenced code, headings, bold, and lists, while mouse-wheel and PgUp/PgDn scrolling work across iTerm2, Terminal.app, kitty, alacritty, xterm, and other mainstream terminals on macOS and Linux.

It is aimed squarely at terminal-first developers: those who prefer a keyboard-driven workflow, run the harness over SSH, or operate inside a multiplexer such as tmux or herdr — where a browser tab is friction, not a feature. Open your terminal, and the full agent workspace is already there.
