中文 | English

dsh-tianshu-tui (@huiliyi37/dsh-tianshu-tui) is the interactive terminal UI plugin for the official DeepSeek Harness. The render core is a self-built minimal ANSI engine (evolved from the author's own open-source Tianshu-Tui, Apache-2.0; file-by-file provenance in SOURCE-MAP.md), keeping rendering lightweight and non-intrusive. The UI is a pure presentation layer: every piece of agent state arrives through the session event stream. On top of it, the plugin adds harness-level engineering niceties such as image & vision bridging, smart code retrieval, and memory with cross-session recall.

Install

This package is not a standalone app. You need the official CLI @deepseek-ai/dsh (npm latest, currently 0.1.5-rc.1; needs ≥ 0.1.5-rc.1, aligned with the peer deps). npm i of this package alone will not run.

One-click install (recommended): the repo ships cross-platform scripts that detect Node/pnpm, install the official CLI via pnpm, wire this plugin and launch (defaults to the npmmirror registry for CN networks):

# macOS / Linux (bash)
bash <(curl -fsSL https://raw.githubusercontent.com/huiliyi37/dsh-tianshu-tui/main/scripts/install-tui.sh)
# install only, no launch:
bash <(curl -fsSL https://raw.githubusercontent.com/huiliyi37/dsh-tianshu-tui/main/scripts/install-tui.sh) --no-launch

# Windows (PowerShell)
powershell -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/huiliyi37/dsh-tianshu-tui/main/scripts/install-tui.ps1 | iex"
# install only, no launch (after cloning the repo):
powershell -ExecutionPolicy Bypass -File scripts\install-tui.ps1 -NoLaunch

1. Prerequisites

• Node.js ^22.19 || >=24
• pnpm on PATH (dsh plugin forwards to it; if missing, corepack enable — Node ships corepack)

⚠ npm 11 OOM pitfall: the official CLI @deepseek-ai/dsh has a large dependency tree (60+ sub-packages); npm 11 (bundled with Node 24) runs out of heap while installing it (hangs for minutes then JavaScript heap out of memory — reproduced). Use pnpm (commands below). If you are already on npx -y @deepseek-ai/dsh and it hangs/throws heap OOM, switch to pnpm.

Do not type dsh by itself. An older dsh on PATH (for example ~/.local/bin/dsh, where dsh --version is below 0.1.0-rc.8) will hit a local staging tree and fail with ERR_FS_EISDIR / Path is a directory .../@deepseek-ai/dsh. Always use the pnpm dlx commands below.

2. Add this plugin to the tui profile

pnpm dlx @deepseek-ai/dsh plugin --profile tui add @huiliyi37/dsh-tianshu-tui

pnpm may warn about missing peers; ignore that. Peers come from the official dsh host. Without pnpm you can also use npx -y pnpm dlx @deepseek-ai/dsh plugin --profile tui add @huiliyi37/dsh-tianshu-tui.

After an npm install, each launch checks npm latest and writes a newer version into the profile, then asks you to restart. You can also run /update inside the TUI for a manual check (check-only; it prints the update command). Set DSH_TUI_SKIP_UPDATE=1 to skip the check. github: / link: installs are left alone.

You can also install from Git: pnpm dlx @deepseek-ai/dsh plugin --profile tui add github:huiliyi37/dsh-tianshu-tui (the repository ships lib/index.js; no rebuild).

3. Start

pnpm dlx @deepseek-ai/dsh --profile tui

Success looks like a welcome screen branded dsh-tianshu-tui. Quit with Ctrl+Q or /exit.

If the official CLI is installed globally (pnpm add -g @deepseek-ai/dsh) and dsh --version is at least 0.1.0-rc.8, you can use dsh in place of pnpm dlx @deepseek-ai/dsh.

4. Agent presets (/preset)

The command is /preset (there is no /presets). This bundle matches official web: it disables the host agent plane and mounts @deepseek-ai/dsh-agent-presets (pinned 0.1.5-rc.1; npm latest still points at stale 0.0.1-rc.1). Adding this plugin installs the roster; new sessions mount in setup. /preset switches the official shipped surface (standard / PTC / minimal / creative), rather than stacking on dsh-base tools.

Usage:

• /preset — list each preset's capability and toolset, * marks the current one; the footer / welcome top bar also show the short name (Standard / PTC / Minimal / Creator). After a turn, wire: shows the last request's tool surface
• /preset <id> — switch to the given preset (blank sessions only: /session new first; ptc/creative alias code/cordis)

If npx still raises ERR_FS_EISDIR, stale install fallbacks under ~/.dsh/profiles/node_modules are colliding with the official CLI. Use a clean home:

DSH_HOME=/tmp/dsh-tianshu pnpm dlx @deepseek-ai/dsh plugin --profile tui add @huiliyi37/dsh-tianshu-tui
DSH_HOME=/tmp/dsh-tianshu pnpm dlx @deepseek-ai/dsh --profile tui

Do not run tsdown for this package from the DeepSeek Harness workspace root: it rewrites imports to unpublished @deepseek-ai/dsh-root, and loading fails.

The companion vision plugin lives in vision-ask/ if you need image re-interrogation.

Release notes

Current npm latest: @huiliyi37/dsh-tianshu-tui@1.0.0-rc.1 (GitHub Release).

1.0.0-rc.1 (2026-09-14): first release candidate of 1.0.0; the version enters the 1.0 line. Four convergences on top of 0.1.2-rc.31 — retry-path body loss fixed (after a successful LLM retry the step's body was dropped whole: each host attempt is an independent attempt, so per-step dedup was a modelling error); failed attempts now get a ⟳ 未完成的尝试 (unfinished attempt) marker before their body so they are not read as one continuous answer with the successful one; assistant stream semantics merged into adapter/assistant-stream as the single implementation (previously four copies, so one host behaviour change needed four coordinated edits); two consumer-less dead states removed (SessionManager snapshot layer, TranscriptView.streaming aggregation). ⚠ Requires host ≥ 0.1.5-rc.1 and node ≥ 24.4.

0.1.2-rc.31 (2026-09-14): fixes #58 — assistant body text missing on normal turns against the 0.1.5 host (attempt events only occur on error/interrupt paths; normal turns deliver text embedded in assistant/message, now rendered at the message boundary with per-step streamed-text dedup). ⚠ Requires host ≥ 0.1.5-rc.1 and node ≥ 24.4 (the 0.1.5 host CLI entry depends on import.meta.main; older nodes exit silently with no output).

0.1.2-rc.30 (2026-09-12): host line moves to 0.1.5 (official latest is now 0.1.5-rc.1) — streaming events assistant/chunk→batched assistant/attempt, the new sessionPersistence contract (snapshot list + open/read handles), defensive rendering for missing timestamps in cross-format stores; real-machine pty e2e green. ⚠ Requires host ≥ 0.1.5-rc.1.

0.1.2-rc.29 (2026-09-09): host line moves to 0.1.2-rc.1 (now the official latest; fixes #56 boot crash) — Session.events removal adapted to snapshotEvents(), userQuestions migrated to a waterfall answerer (global registration), CallId→ToolCallId, preset code→ptc, fork lineage via isSeeded+inheritedEventCount, bundle patch gains subagent-model-selection-settings; older hosts (≤0.1.1-rc.2) fail loud at startup with upgrade/rollback guidance. ⚠ This release requires host ≥ 0.1.2-rc.1.

0.1.2-rc.28 (2026-08-29): vim improvements answering #55 — mode-distinct cursor (block in NORMAL / bar in insert), two-phase history search (queries may contain n/N; Enter to confirm then jump; the search target is now labelled), search-term highlight (also in /scroll); plus auto-refill of the input line on delivery failure and a README-keymap consistency guard.

0.1.2-rc.27 (2026-08-29): two backports from Tianshu — actionable errors (beyond the full error commit + recovery hint, the last delivered message is auto-refilled into the input line with a ↩ "may not have been fully processed" note; edit and re-send; cleared on successful turns, drafts never clobbered); plan-review decision-card visual layering (dim decision-zone divider + ❯/success primary-action highlight; rendering byte-identical when no theme is passed).

0.1.2-rc.23 (2026-08-27): LSP trio aligned to the upstream 0.6.0 official seam line (single lsp tool with four operations + local provider defaulting to tsserver), capability-gated diagnostic source prevents /lsp panel regression; host peers aligned to ^0.1.1-rc.2.

0.1.2-rc.22 (2026-08-27): LSP model tool surface shipped bundled first version (companion plugin auto-inserted; remove the legacy community plugin).

0.1.2-rc.21 (2026-08-27): three community fixes — inverse-video input caret (#50), preset defaults to standard (#48), root-cause + upstream report for malformed SSE payload (#49).

Full release history: CHANGELOG.md (zh) and GitHub Releases. In the TUI, /changelog shows the current release (/changelog all for everything).

Highlights

• Full session workspace in a terminal — live rendering, append-only scrollback, session restore on startup, /fork exploration branches, /rewind rollback (session truncation + optional file rollback), /export to Markdown transcripts, and mid-turn steering (/steer / Ctrl+T).
• End-to-end images — paste from clipboard (Ctrl+V / terminal-menu paste), render as inline terminal graphics (kitty / iTerm2), deliver through the harness attachment service, and let a vision-capable model actually see them — with an automatic vision bridge that describes the image through a separate vision model when the main model cannot see.
• A complete input surface — grok-style slash dropdown menu (fuzzy prefix matching, MRU ordering, ghost previews), @-path Tab completion and @mention expansion, bracketed paste, optional vim keybindings, external editor (Ctrl+E), history search (Ctrl+F/Ctrl+R) — and a full keymap overlay behind Ctrl+..
• In-terminal interaction surfaces — structured question panels (numeric selection, plan-review feedback mode), pending approval cards with inline diff previews, mode cycle (Shift+Tab: normal → plan → always-approve), command palette, and live panels for status / config / skills / tasks / delegation / workflow.
• Reasoning made visible — the think channel streams as a live header, folds into a compact scrollback line (✻ 思考 (3.2s) · 12 行), and expands in place with Ctrl+O (competitor-aligned: collapsed by default).
• Personalized harness integrations — /doctor terminal diagnostics, /memory project-memory browser, /btw side questions to a background agent, /model + /effort hot-switching that takes effect on the current session immediately.
• Auditable by construction — the TUI registers no prompt, tool, or context surface of its own; user input becomes ordinary logged messages, and every rendered state derives from session events.
• Co-evolved with the harness — built in lockstep with harness-side capabilities on the 2026-08-09 baseline snapshot (250+ commits): the image/vision pipeline, DeepSeek Spark model engineering, session persistence and file snapshots, memory, the validation gate and failure routing, code intelligence, and the git tool. See the next section.

Co-evolved harness capabilities (since the 2026-08-09 baseline)

The terminal UI evolved from Tianshu-Tui (Apache-2.0; per-file provenance in SOURCE-MAP.md). This bundle then developed in lockstep with harness-side work on the DeepSeek Harness baseline snapshot snapshots/20260809T140917Z — 250+ commits between 2026-08-10 and 2026-08-13. The capabilities below live in the host harness (separate packages, not shipped in this bundle); the TUI is their primary interactive surface:

• Image pipeline & vision bridge — the image ContentBlock joins the merge-extensible content vocabulary and dsh-llm-deepseek serializes user image blocks as OpenAI-style image_url content parts, so user images reach the wire end-to-end (clipboard → input line → session → model request). Models declare supportsVision (LlmModelInfo + llm-deepseek catalog). dsh-vision-bridge covers text-only main models: at agent/pre-step it describes image attachments through a separate vision model (visionAutoBridge auto-selects the first vision-capable model when provider/model are omitted; fallback model + data URL validation; the prompt auto-selects between general structure and OCR-level transcription based on UI/error keywords), injecting the description as a plugin-source user message — Model-visible ⟺ logged; bridge failure degrades to a visible hint, never a failed turn.
• DeepSeek Spark aliases — the official API has no spark model and this host does not register a deepseek-spark provider. /model spark-flash / spark-pro map onto the registered deepseek-official route with wire ids deepseek-v4-flash / deepseek-v4-pro.
• Session persistence & file snapshots — Session.truncate rewinds the event log and resets derived state; persistence backends gained deleteFrom plus a truncate coordinator, so rollback survives reload; dsh-fs-snapshot ports FileHistory (trackEdit / rewindToBoundary) and snapshots before write-tool execution. TUI surface: /rewind (conversation truncation + optional file rollback).
• Memory — dsh-memory (MemoryService + Markdown file backend, non-git fallback) and tool-memory (memory_save / memory_search + memory-digest injection) provide cross-session recall. TUI surface: /memory, /remember.
• Validation gate & failure routing — dsh-evidence-gate enforces RED-first verification: obligation state machine, edit/verify counters, TDD gate (enforce mode), probe suggestions with cooldown, and an L2 final-review gate, natively wired into str_replace_editor and the headless-agent assembly. dsh-agent-router predicts step failure from turn history and routes work — verification-subagent dispatch and per-profile tool restriction — with real-turn e2e coverage.
• Code intelligence & retrieval — dsh-semantic-index (BM25 + salience/RRF/vector fusion, incremental updates) exposed as the semantic_search tool; dsh-meridian code index (node:sqlite schema, tree-sitter parsers for TypeScript/Python/Go, graph/impact/flow queries, behavioral signals, background backfill) exposed as repo_graph and the <codebase-index> digest; dsh-pheromone file-level pheromones with atomic JSON persistence, surfaced through file_info and the read tool's focus semantics.
• Git service & tool — dsh-git service seam (GitLocal CLI provider, service-class-as-plugin) plus dsh-tool-git, a single model-facing git tool with an operation discriminator (status / diff / log / commit), assembled in the base bundle.

Features

Session management

Capability	Description
/session new|list|switch	Create, list, and switch sessions; resume replays the full transcript through the same render bridge
Restore panel	Recoverable sessions are listed in scrollback at startup
/fork [directive] · /branch	Fork the current session (history copied to a new child session) and optionally start it with a directive
/rewind	Roll back to a chosen message — conversation truncation and/or file rollback to the pre-boundary snapshot
/export	Export the current session transcript to a Markdown file
/clear	Clear the scrollback view of the current session

Input surface

• Slash command menu — typing / opens a dropdown with fuzzy prefix matching, ↑↓ / PageUp / PageDown selection, Tab accept, Enter submit, MRU ordering, argument-placeholder ghosts, and an input-line ghost preview.
• Clipboard & image paste — Ctrl+V reads a clipboard image (falling back to text); terminal-menu paste detects images; pasted paths that look like images are loaded as attachments; Alt+W / vim yank copies selection to the system clipboard via OSC52.
• Image submission — attached images show a 📎 N images marker, render inline under the user bubble on submit, and reach the model through the attachment service; the bubble carries a vision hint (forwarded / bridged via a vision model / not sent). Oversized pastes are adaptively compressed before send: 1568px long-edge clamp (PNG keeps transparency), degrading JPEG 0.82 → 0.55 → 1024px + 0.55 until under the provider cap, never upscaling.
• Vim editing (#51) — Esc enters NORMAL; the keymap mirrors Claude Code: h j k l / w e b W B E / 0 $ ^ / gg G / f F t T ; ,, operators d c y × motion with counts, text objects iw aw iW aW, linewise dd cc yy Y plus p P paste, x X D C s S r o O J u .; v/V visual selections include the character under the cursor (vim ownership semantics). Multi-line drafts move column-wise with j/k; CJK runs count as single words. Toggle at runtime with /vim; /vim default makes it the startup default. Insert-mode two-key sequence → Esc mappings (vimInsertRemaps, e.g. {"jj":"esc"} in prefs; 1s window guards against accidental triggers). Cursor shape follows the mode: block (reverse video) in NORMAL, bar in insert (#55). NORMAL / opens session-history search (two-phase: filter as you type, Enter to confirm then n/N jump — queries may contain n/N).
• Editing — external editor (Ctrl+E), Tab file completion, @mention expansion, input history, multi-line input, and bracketed paste (multi-line / long pastes land in the input line as one block instead of submitting line by line); the input line is drawn as a full rounded frame.
• Message queue while running (Claude Code queue parity) — messages submitted while the agent is running enter a local queue shown above the input rail (echoed immediately, not sent); they flush in order at the next turn end, and an aborted turn does not auto-flush (leaving room to take them back with ↑); empty-input ↑ pops the first queued item back into the input; switching sessions drops the queue with an echo. Mid-turn immediate steering stays on /steer / Ctrl+T.
• Image re-interrogation — the companion @deepseek-ai/dsh-vision-ask plugin registers sent images and answers targeted model questions via ask_image (see vision-ask).

Rendering & projection

• Conversation stream — markdown rendering, tool-family coloring with per-tool timing, and parallel tool calls folded into groups.
• Tool cards commit in real time — settled tool results render as scrollback cards consuming the harness presenter intent: diff results as structured red/green file diffs (shared with the approval preview), terminal results with command title + cwd + exit/signal badge, everything else as folding cards.
• Reasoning channel — shimmer live header while thinking, folded scrollback line at segment end, Ctrl+O expands the full text in the live area.
• Fluency folding — repetitive routine tool traffic collapses under a quiet strategy; compact mode (/density) keeps header-only lines.
• Turn status — braille spinner + phase text status line, workflow-run summaries, delegation tree, task pane, config/skills panels as live-region panels; a non-aborted turn with tool calls ends with a dim summary line (turn N · 读X 改Y · elapsed) in the scrollback.
• Subagent runs — a live spinner line per run; terminal states commit to scrollback as ✓/✗/◌ entries.
• Window chrome — welcome page (brand header, friendly short session ids, environment check line), top bar (cwd + git branch + model), and a three-line bottom area: input line (mode-colored bottom edge) → footer (mode badge + key hints) → metrics line (model / token usage / cache hit rate).
• Themes — built-in palettes plus custom:<name>; auto terminal detection and 16-color fallbacks; honors NO_COLOR; custom themes get contrast warnings on load (WCAG < 3.0 against the declared background, non-blocking).

Interaction panels

• Structured questions — numeric selection, Esc cancels, overlap protection; plan-review feedback mode (f to enter, Enter submits Keep-planning + custom feedback).
• Approval cards — y/N/Ctrl+C settle pending approvals; inline diff previews when the tool is diffable; blind-approval hint when the diff is invisible; non-current-session requests delegate to the next listener.
• Mode cycle — Shift+Tab cycles normal → plan → always-approve; the plan state drives the footer badge, and always-approve is session-local (resets on switch/exit).
• Live panels — /status (goal/todos/plan projection snapshot; the subagent domains surface under /subagents), /config (terminal notifications (completion OS notify + BEL bell — the bell still reaches you over SSH) / compact rendering + host settings / permission / credentials), /skills browser (↑↓ details), /tasks pane, /subagents delegation tree, /workflow runs. Inspect panels are exclusive; Esc closes them. Missing host sections collapse; /config's terminal section does not need the host. Other panels echo a ⚠ warning when their backing service is absent instead of going silently blank.
• Command palette (Ctrl+P) / keymap (Ctrl+.) / history search (Ctrl+F/Ctrl+R) overlays.

Models & vision

• /model — view and switch the model (default + hot-switch for the current session); spark-flash / spark-pro aliases map to deepseek-official + the official wire ids deepseek-v4-flash / deepseek-v4-pro. /model <provider/model|alias> [off|high|max] sets the reasoning effort in the same command.
• /effort — set the reasoning effort (off / high / max; auto returns to the model default), hot-switched for the current session.
• Vision bridge — vision capability is declared per model (supportsVision, auto-refreshed from the llm catalog) and drives the bubble hint; when the main model cannot see images, an automatically selected vision model describes them before submission (one-shot path; see Known Limitations). Bridge availability comes from the assembly layer (vision.bridgeEnabled) or from a host vision-bridge plugin providing the visionBridge service — the TUI probes service presence before submitting images; with neither, images are not sent and a warning is shown.
• Vision co-pilot — with the companion @deepseek-ai/dsh-vision-ask plugin (same repository), every sent image is registered under a short id (img_1, …) and the model can re-interrogate it with ask_image — targeted questions, different angles, any number of times; repeated same-angle asks hit the per-image description cache. Details and config in the vision-ask README.
• /mcp — list connected MCP servers and tool counts; tools <name> inspects a server's tool list.

Assembly

The bundle patch inserts the tui-runner plugin over dsh-base:

- id: tui-runner
  name: '@huiliyi37/dsh-tianshu-tui'

TuiRunnerConfig (all optional): stdin/stdout (stream injection, defaults to process streams), initialSessionId, editorKey (default ctrl_e; ctrl+o is reserved for reasoning expansion), vimEnabled (default false), vision (supportsVision / bridgeEnabled / bridgeSource; when omitted, supportsVision auto-refreshes from the llm catalog and bridgeEnabled is auto-probed from the presence of the host visionBridge service — a vision-bridge plugin should provide it), workflowHistoryLimit (default 50).

Service dependencies: sessions/agents/agentDefaultModel required (mandatory inject); goals/subagents/memory/compact/tasks/skills/sessionProjections/workflowEngine/planMode optional — when unassembled, the affected commands and panels degrade fails-loud with an availability message, never silently, and never block TUI startup.

Verification

npm test

Model Experience

None, as the TUI renders logged session events and forwards ordinary user input; it registers no prompt, tool, or context surface.

KV Cache effect

None directly; user input submitted through the TUI becomes ordinary logged messages whose request effects belong to the session and loop packages.

Known Limitations and Deferred Work

• LSP bridge runtime limits — the model tool surface (goto/find/diagnostics) ships bundled (@huiliyi37/dsh-lsp companion plugin, auto-inserted by the bundle patch); deeper integrations like Tianshu's edit-diff diagnostics-narrowing remain future work. Servers slower than the timeout (default 2s) silently yield no diagnostics until the file is touched again; large-repo tsserver stays resident (lazy start mitigates, no idle reclaim); switching sessions does not restart servers (rootUri follows the first session's cwd).
• Image re-interrogation requires the companion plugin — the ask_image tool and the session image registry live in @deepseek-ai/dsh-vision-ask (same repository, separate package); the TUI bundle itself does not ship them. Without the plugin, an already-sent image cannot be re-queried and repeated same-angle descriptions re-call the vision model; the vision bridge still covers the one-shot submit-time description path.
• app.ts monolith (~3.2k lines) — the pending-state state machines are controller-ized (question/approval), while render composition and key arbitration remain in app.ts; the C4 split plan (pure-function panel segments) keeps advancing.
• Projection layer partially wired — of the four pure fold models, turn-summary (turn/end summary line) and summary-state (the /status session-totals section, which keeps working even when the host projection bus is absent) are wired; activity-status/activity-store stay deliberately unwired (the statusline is a self-contained projection, so replacing it buys nothing; activity-store has no current consumer). Current state is recorded in docs/projection-layer.md.
