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, GitHub light/dark themes and a powerline footer.

Requires dsh >= 0.1.2-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 See ADR 0002 for the now-superseded alpha single-target decision.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 — switch a whole model setup per project and keep the picker small.
• Agent preset switching — /preset between the shipped agent compositions (standard, minimal, …); a switch is confirmed and starts a NEW session on the preset (the current one stays resumable); what a preset really gates.
• Sessions & resume — sessions stay tidy automatically and resume in a few keystrokes; a cross-process writer guard keeps the log single-writer.
• 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, no writer lock).
• Themes — GitHub light/dark palettes, 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, /profile-switch, … plus everything dsh-native.
• 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 (missing identity.isSeeded/identity.inheritedEventCount, written before dsh 0.1.2-alpha.4 — predating the rc/stable floor of 0.1.2-rc.1 this plugin now targets) are migrated at the profile layer: the bundle patch replaces the stock session-projection-cache row with a wrapper (@aiwayds/dsh-tui-pi/projcache) that backfills the records while its module loads — strictly before the stock plugin could open the domain and crash the boot — so every dsh --profile tui start is covered, launcher or not. Migration is idempotent, backs up every rewritten file next to the original, and never blocks startup. The dsh-tui-pi launcher additionally runs the same migration as a CLI preflight before exec dsh.

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.

What stays on disk on purpose (deleting user data is destructive; a reinstall reuses all of it):

• ~/.dsh/APPEND_SYSTEM.md — auto-seeded system-prompt appendix (plugin-owned; delete by hand if unwanted)
• ~/.dsh/tui-command-usage.json — slash-command usage ranking
• ~/.dsh/model-profiles.json — model profiles (SHARED with other plugins — dsh-subagent-registry reads it)
• ~/.dsh/keybindings.json — the dsh-tui app-key rows (host-shared file)
• ~/.dsh/agents/*.md and ~/.dsh/skills/ — user-editable agents/skills (shared with other plugins)
• .dsh-profile pin files in project workspaces (written by /model profile pinning)
• the dsh-tui: section of ~/.dsh/settings.yaml — theme/panel/footer/retention/subagent limits
• ~/.dsh/storages/session_projcache/ — the session projection cache, incl. .bak-preflight-* migration backups

While the plugin runs, the retention janitor (default maxCount: 100 / maxAgeDays: 7, configurable in the dsh-tui settings) 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 eight 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-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

Every knob lives under the dsh-tui settings namespace in ~/.dsh/settings.yaml (note the section name: dsh-tui). Theme / panel height / footer hints / icon set are applies: 'live' — a committed change hot-applies to the running TUI, no restart:

Session-store knobs (env overrides DSH_TUI_RETENTION_* / DSH_TUI_RESUME_*; precedence: settings.yaml > env > default):

dsh-tui:
  retention:        # startup janitor for ~/.dsh/sessions — DELETES old logs. Once per startup.
    maxCount: 100   # <= 0 disables the janitor
    maxAgeDays: 7
    minIdleHours: 24
  resume:           # /resume display filter — only HIDES picker rows, never deletes.
    maxAgeDays: 7
    minBytes: 20480

Key remaps live in ~/.dsh/keybindings.json (keyboard section above); DSH_TUI_COPY_ON_SELECT=0 keeps drag-selection visual-only.

The plugin ships a bundled skill (dsh-tui-pi-config): ask the agent to "configure the TUI" and the guide loads automatically — it collects your choices interactively via ask_user_question (theme, panel height, subagent concurrency) and writes the dsh-tui: 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; 1,100+ tests across 60+ files — 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.
