dsh-tui-pi

English | 简体中文

dsh-tui-pi

A fully-featured pi-style terminal UI for DeepSeek Harness (dsh) — a plugin suite that turns dsh into a pi-like coding-agent experience: /history look-back & fork-at-turn, guided preset switching, live subagent steering, model profiles, 20+ built-in themes (10 light + 10 dark) with user theme directory discovery, and a powerline footer.

Requires dsh >= 0.1.7-rc.1 — this plugin targets the dsh RC/stable line only (CI and releases resolve the newest of the latest/next dist-tags at runtime). The alpha line is no longer supported. A startup guard logs a one-line warning and exits cleanly when the host is older than the floor (opt out with DSH_TUI_SKIP_HOST_CHECK=1). See ADR 0002 for the now-superseded alpha single-target decision.

A live recording of a session (MP4, 1.5× speed) — todos, running subagents, think/tool panels and the powerline footer in action.

✨ Features

Each item links to its own doc under docs/features/ — one line here, the details (and demo videos) there.

• Footer — live session overview — provider/model, context pressure and the session cache-hit rate at a glance, always in view.
• Think & tool panels — reasoning and tool activity stay out of the transcript, so the conversation reads clean.
• Subagents — every running subagent gets a status line; watch and steer it live.
• Ask User Question — the model can pause and ask you structured questions, answered without leaving the TUI.
• Feishu integration — dsh-tui-pi on the desktop and Feishu/Lark on the phone driving (and answering for) the same dsh session.
• Dynamic context pruning (DCP) — context stays within limits automatically, with zero LLM calls.
• Persistent context — your ground rules ride along on every request, hot-applied with no restart.
• Model profiles & favorites — profile switching lives in dsh-profile-switch now; this suite keeps the TUI read side (session seeding from the pin, live-selection bridge, scope-aware /agents edits) and the /model favorites that keep the picker small.
• Agent preset switching — /preset between the agent presets the host's 0.1.7 registry declares (standard, minimal, …); a switch is confirmed and starts a NEW session on the preset (the current one stays resumable); what a preset really gates, and how to migrate a 0.1.5 directory preset (same-id bundle patch).
• Sessions & resume — sessions stay tidy automatically and resume in a few keystrokes; the host's kernel write lease keeps the log single-writer across processes.
• History browser — /history opens a fixed two-pane look-back over the session: completed turns on the left, the selected turn's replies on the right; copy a prompt back to the editor, or cold-read any stored session without resuming it (read-only).
• Themes — 20 built-in palettes (10 light + 10 dark) plus user theme discovery (~/.dsh/themes/); hot-switchable, auto follows your terminal.
• Search, selection & images — Ctrl+Shift+F over the whole transcript, drag-select copies to the OS clipboard, attachments from web/Feishu render inline, LaTeX replies draw as Unicode math.
• Slash commands — /model, /resume, /btw, … plus everything dsh-native.
• Settings browser & UI languages — /settings edits everything in place (alphabetical categories, per-provider model lists, a Subagent group); /language switches the UI language from any surface.
• Startup plugin tree — every profile plugin with its installed npm version, printed at launch.

Install and launch

dsh plugin --profile tui add @aiwayds/dsh-tui-pi
dsh --profile tui          # launch (or: dsh-tui-pi)

Legacy session_projcache records (written before dsh 0.1.2-alpha.4) are migrated automatically at profile load — idempotent, with per-file backups, never blocking startup; the dsh-tui-pi launcher runs the same preflight.

Everything that used to need manual patching — the canvas background, the @deepseek-ai module closure, the compaction backend — now happens automatically. Upgrade an existing profile after a release:

node scripts/dev-upgrade.mjs                  # latest
node scripts/dev-upgrade.mjs 1.0.5 --dry-run  # preview the plan first

Uninstall

dsh plugin --profile <name> remove @aiwayds/dsh-tui-pi

The dsh-tui-pi bin shim is global and can stay; if you installed the package globally and want it gone too: npm -g rm @aiwayds/dsh-tui-pi.

The host cleans up the profile automatically: the dsh.profile.bundles entry is spliced and the whole patch layer goes away with the package — the stock session-projection-cache row re-enables, and the projcache wrapper, the tool-ask-user insert and its disable row all vanish.

User data stays on disk on purpose (deleting it is destructive; a reinstall reuses all of it): ~/.dsh/APPEND_SYSTEM.md, tui-command-usage.json, model-profiles.json, keybindings.json, ~/.dsh/agents/ + ~/.dsh/skills/, workspace .dsh-profile pins, the dsh-tui entry config in the profile patch (a pre-0.1.7 settings.yaml section lands there as settings.yaml.imported), and the session projection cache (incl. .bak-preflight-* migration backups). While the plugin runs, the retention janitor (default maxCount: 100 / maxAgeDays: 30) deletes old session logs — uninstalling stops that, but already-deleted logs are gone. scripts/install-font.mjs mutates OS font/terminal state and has a documented backup; uninstall doesn't touch it.

Companion plugins

Default dependencies — the nine plugins below ship with this package (installed into the profile's node_modules); activation still follows the profile's bundles list — list each one there to activate it.

• @aiwayds/dsh-ask-router — fans every ask_user_question out to all answering surfaces (TUI panel, Feishu card); the first answer wins — list it in bundles before the UI bundles to activate.
• @aiwayds/dsh-dcp — the deterministic zero-LLM compaction backend.
• @aiwayds/dsh-llm-proxy — SYSTEM proxy + per-host LLM outbound routing.
• @aiwayds/dsh-llm-stats — the /llm-stats usage ledger.
• @aiwayds/dsh-mcp-adapter — folds MCP tool schemas out of every prompt and adds the /mcp command (demo).
• @aiwayds/dsh-model-sync — syncs provider routes with the pi.dev model catalog.
• @aiwayds/dsh-profile-switch — /profile-switch + /profile-cfg: named model profiles switched and configured through the host's ask-user flow, on the TUI and the web (the panels this suite used to carry). Add it to your profile's bundles to activate.
• @aiwayds/dsh-subagent-registry — registers ~/.dsh/agents/*.md as use_agent subagents.
• @aiwayds/dsh-web-search-anysearch — the AnySearch web search provider.

Recommended install — @aiwayds/dsh-topics-memory, OKF topic memory for dsh (zero-LLM hot-path injection + a local git-tracked bundle; formerly dsh-llmwiki-memory):

dsh plugin --profile tui add @aiwayds/dsh-topics-memory

Optional — @aiwayds/dsh-feishu — drives the same dsh session from Feishu/Lark on your phone (demo).

Keyboard shortcuts

Remap any app key through ~/.dsh/keybindings.json (a partial JSON map, live-applied) or interactively with /hotkeys.

Configuration

Everything lives in the plugin's dsh-tui entry config inside your profile's cordis.patch.yml (dsh 0.1.7 projects every volatile field of a plugin's declared Config schema into the settings surface) — but you rarely touch the file: /settings browses and edits it in place (searchable categories — Agent Presets / General / Models / Plugins / TUI — with live values, per-field descriptions, and an add-provider flow under Models). Language, theme, panel height, footer hints and icon set hot-apply on change; the rest reads at the next launch.

Most knobs have sensible defaults and need no configuration. The few you might actually set:

- id: dsh-tui         # the plugin's entry row in the profile patch
  config:
    language: zh-CN   # UI language — or just /language (asks on any surface; bundled: en, zh-CN, ja, ko)
    theme: auto       # auto / light / dark / any registered theme name — or /theme
    maxAgents: 4      # subagent concurrency, 0 = unlimited (also tunable in /agents → l)

/agents → l also mirrors the OFFICIAL dsh-subagent caps (maxActiveSubagents, default 8; maxDepth, default 1) as read-only rows — those belong to the subagent plugin entry and are edited in /settings, while the panel's own rows (maxAgents / maxRounds / maxRoundsGrace / the two fences) stay hot-editable here.

Upgrading from dsh 0.1.5? Your old ~/.dsh/settings.yaml dsh-tui: section is imported into the profile automatically on the first 0.1.7 boot (the original file is kept next to it as settings.yaml.imported).

Adding a UI language is one JSON file in ~/.dsh/locales/ — a same-id file merges per key over the bundled one, a new id registers (details: Settings browser & UI languages). The session-store janitors (retention / resume) and ask-user timeouts (askUser) live in the same entry config with documented defaults.

The plugin ships a bundled skill (dsh-tui-pi-config): ask the agent to "configure the TUI" and it collects your choices interactively and writes the section for you. The full key table and the DSH_TUI_* env var list live in skills/dsh-tui-pi-config/SKILL.md.

Development

pnpm check    # tsc --noEmit
pnpm build    # emit lib/
pnpm test     # unit tests, node --test against lib/ (pretest builds — the current baseline lives in AGENTS.md)

pi-tui runs pristine from npm — no patches, no fork. See AGENTS.md for the iron rules and quality gates.

Compatibility note

Resuming, under a dsh 0.1.6 host, a session saved under dsh 0.1.5-rc.2 whose subagent completion notices carried reasoning content fails to serialize the first model request (upstream B-21 — host-side data issue, not a plugin defect). If /resume fails this way, start a new session instead.
