dsh-TUI

An interactive terminal UI plugin for DeepSeek Harness. It ships a pixel-whale header, live work status, streaming thinking, double-Esc time rewind, a context progress bar, and a TPS gauge. It mounts as a pure plugin, with no core changes. Install to enable; uninstall leaves no patches behind.

Highlights

• Pixel whale pet — three startup intros, click to wake; freezes after the first task.
• Terminal-native UI — streaming Markdown, tool cards, / and @ completion, #L12-14 ranges, history search, zh/en UI.
• Images — Kitty/Sixel thumbnails, centered preview with zoom and pan, paste-time fitting, text fallback.
• Mermaid diagrams — mermaid fences drawn as Unicode diagrams.
• LaTeX math — $…$ and $$…$$ formulas rendered as Unicode, fractions and limits stacked in display blocks.
• Timeline rail — every turn clickable; timeline / scrollbar / hidden gutter.
• Live state — activity animation, context bar, TPS, cache hit rate, effort, tokens, Git and session metadata.
• One session manager — /resume /home /agentview /bg ⌸.
• Session workflow — /new /compact /export /btw, model hot-switch, fork, rewind, vim, fullscreen draft editor.
• IDE selection channel — a VS Code selection lands in the prompt.
• DSH integrations — presets, skills, MCP, goals, todos, subagents, questionnaires.
• Extensions — browser interaction, computer use and more.
• Built for long sessions — event-driven projection, virtualization, bounded caches.

Quick Start

Prerequisites: Node.js and deepseek-harness, with DEEPSEEK_API_KEY configured.

The primary compatibility target is DSH 0.1.7-rc.2. This adapter supports its Shell API, V4 session messages, declarative presets, and profile-backed settings; older supported hosts retain their compatibility paths. See configuration.

On DSH 0.1.7, /settings uses the TUI's actual Loader entry ID, including custom IDs. It requires matching profile dependencies with @deepseek-ai/schemastery 3.18.3 or newer; an incompatible schema stops TUI startup with repair guidance instead of showing an uneditable settings page. Older hosts keep their legacy settings scope.

# Install the CLI and this plugin globally (ships the dsh-tui command)
npm install -g @deepseek-ai/dsh @deepseek-harness-tui/dsh-tui

# Start (first run auto-initializes the profile; needs pnpm)
dsh-tui
# Both `dsh-tui` and the short `dst` alias start the same TUI.
dst

Manual alternative: dsh plugin --profile dsh-tui add @deepseek-harness-tui/dsh-tui. The repo's sh install.sh runs that step and checks the required commands. Afterwards dsh-tui and dsh --profile dsh-tui are equivalent.

New-user note: pnpm ≥11 blocks dependencies with install scripts by default and reports ERR_PNPM_IGNORED_BUILDS. Updates skip foreign-platform @img/sharp-* native packages, saving about 200MB of downloads. /update and dsh-tui update write both settings automatically. No manual step needed. Details: Getting started.

After startup the TUI checks for newer versions in the background. It never blocks the first frame. Type /update for a one-shot upgrade. It restarts automatically and resumes the current session. See Getting started for the profile lifecycle, source builds, and troubleshooting, including migration from the former dsh-cc-tui package.

CLI

Command	Purpose
dsh-tui / dst	Start the TUI; dst is a short alias for the same program
dsh-tui --resume [id] · dsh-tui update · dsh-tui doctor	Resume a session · update the profile and align the launcher · pre-flight environment checks
dsh-tui safe	Read-only diagnostics, plugin inventory and repair guidance; safe --rescue builds a clean rescue profile
dsh-tui version · dsh-tui help	Launcher and profile versions and usage; both work even without a dsh install

Other arguments go to dsh --profile dsh-tui. Safe mode: Getting started.

Importing conversations from other agents (dsh-tui migrate)

Bring Claude Code, Codex, OMP, zcode, or Grok Build conversation histories into the DSH session store, then browse and resume them by their original working directory via /resume:

dsh-tui migrate                # list importable counts per agent (writes nothing)
dsh-tui migrate claude-code    # import every Claude Code conversation (likewise codex / omp / zcode / grok-build)
dsh-tui migrate codex --dry-run  # preview what would land, write nothing

• Read-only source: migration only reads the foreign agent's local store; artifacts are written through the official JsonlSessionPersistence backend, so imported sessions are first-class (openable, continuable).

• Idempotent: one deterministic UUID per source conversation — re-importing skips what is already present instead of stacking duplicates.

• Structure preserved: user/assistant messages and reasoning traces are rebuilt turn by turn; tool traffic is not migrated (source formats cannot replay it faithfully — the contract is "re-read the conversation", not "resume the task"). In-TUI: /migrate (optionally /migrate <agent> [--dry-run]) runs the same import in a child process and reports through the notification flow. CLI alternative: dsh-tui migrate ... from any shell runs the same import. Full guide: Session migration.

• More agents (pi, opencode, …) extend the adapter registry as adapters land; grok-build reads GROK_HOME when set.

VS Code: use the integrated terminal or the dsh-tui-vscode extension. See VS Code guide. Herdr: run dsh-tui in a Herdr pane; idle / working / blocked are reported through its local integration API.

Keybindings & Mouse

Enter send · Tab complete · Ctrl+Enter interrupt and send · Alt+Up recall the last message · Esc dismiss, double-Esc rewinds · Ctrl+O details · Ctrl+R history · Ctrl+V paste · Ctrl+Shift+E fullscreen draft editor · ? shortcuts · ← background the session.

While the model is working: Enter steers, Tab queues a follow-up, Ctrl+Enter interrupts and sends.

Mouse (fullscreen): drag to select and copy, double/triple click to select a word or line, click tool cards, timeline ticks and [Image #N] previews.

Full reference: Interaction and commands.

Built-in Commands

/resume · /home · /agentview · /bg · ⌸ open the same session manager: workspace rail, live state, filter, ★ pins. Also /model /new /compact /export /btw /tree /fork /rewind /settings /status /cost /jobs /skills /mcp /login /update.

The session manager paints the last successful list immediately while it checks the persistence store for changes. Titles that require a deeper log scan appear first with a fallback name and update in place when recovery finishes.

Background sessions: /bg or ← on an empty prompt; Esc returns. They run in this process and stop when the TUI exits. Logs survive.

How It Works

dsh profile → dsh-base → dsh-TUI Cordis patch → agent preset + DSH services
  → session/event → Channel projection → React components → Ink/Yoga renderer → terminal

The TUI handles interaction and presentation. The session log is the source of truth. DSH services own models, tools, and persistence. Long sessions render in O(visible window).

Runtime path, module boundaries, performance notes and persistence locations: Architecture and limitations.

Known Limitations

• Injected plugin context has no standalone display; it counts into the context segments.
• /model switches by forking the session; the old session stays in /resume.
• Ctrl+V needs platform clipboard tools; unsupported bitmap formats are rejected.
• A background session lives inside this process and stops when the TUI exits.
• /thinking is not persisted; /compact is unavailable under the minimal preset; /update needs a dsh --profile launch and is refused while a turn is running.

Development

CI uses Node 24 and pnpm 11. The package supports Node ^22.19 || >=24.

pnpm install --frozen-lockfile
pnpm build
pnpm smoke

lib/types/ is ignored generated output. pnpm build recompiles it from a clean output directory and runs the build gates. Git URL installs are not supported. The source manifest keeps @dsh-std/* as workspace deps and vendor/dsh-std as a submodule. pnpm ≥11 also refuses git-hosted prepare scripts by default. Install the registry package instead: dsh plugin --profile dsh-tui add @deepseek-harness-tui/dsh-tui. Rendering, questionnaire, or tool-card changes also need the matching regression scripts.

Permissions and Security Boundary

Windows security warning: the Windows profile defaults to danger-full-access with approval set to never, so tools have unrestricted access. Inspect and tighten the profile before starting next to sensitive credentials or in an untrusted repository.

No sandbox of its own: dsh-TUI uses the active DSH profile's filesystem, shell, sandbox and approval policies. Permission presets come from the DSH permissionPresets registry.
