Mohamed Boudra d9e14186ce refactor(server): extract terminal stream state manager from daemon client
Move terminal stream buffering, handler fanout, and ack offset state out of DaemonClient into a focused TerminalStreamManager.\n\nReasoning:\n- daemon-client.ts mixed RPC transport concerns with terminal stream state machine details.\n- terminal buffering/ack logic is cohesive and testable in isolation, so splitting it lowers logic density and makes future stream changes safer.\n\nWhat changed:\n- Added daemon-client-terminal-stream-manager.ts to own stream handlers, buffered chunks, and ack monotonicity.\n- Updated DaemonClient to delegate terminal stream state transitions (subscribe, receive chunk, clear stream/all, note ack).\n- Preserved public API by re-exporting TerminalStreamChunk from daemon-client.ts.\n- Hardened daemon-client tests to assert behavior (no delivery/ack after detach or stream_exit) rather than private internal maps.\n- Added dedicated manager unit tests for buffering, eviction, handler-failure behavior, and stale ack suppression.\n\nVerification:\n- npm run test --workspace=@getpaseo/server -- src/client/daemon-client.test.ts src/client/daemon-client-terminal-stream-manager.test.ts\n- npm run typecheck\n\nNext-agent notes:\n- Accomplishment: terminal stream state is now isolated; daemon-client.ts is slimmer and easier to extend.\n- Challenge: daemon-client.ts is still large (~3k lines) with other cohesive seams remaining (dictation flow and checkout RPC groups).

Voice Assistant

A voice-controlled terminal assistant that runs as a single local service.

Quick Start

# Install dependencies
npm install

# Copy environment variables
cp .env.example .env
# Edit .env and add your API keys (OpenAI, Deepgram)

# Run development servers
npm run dev

# Open browser to http://localhost:5173

Architecture

  • Express Server (port 3000) - Serves API and built UI in production
  • Vite Dev Server (port 5173) - Hot-reload React UI in development
  • WebSocket (/ws) - Real-time bidirectional communication
  • Agent - STT → LLM → TTS pipeline with terminal control
  • Daemon - tmux-based terminal management (in-process)

Development

# Run both servers (recommended)
npm run dev

# Or run separately:
npm run dev:server  # Express on port 3000
npm run dev:ui      # Vite on port 5173

# Type checking
npm run typecheck

# Build for production
npm run build

# Start production server
npm start

Project Status

Completed (Phases 1-2):

  • Package setup and configuration
  • Express server with WebSocket
  • React UI with Vite
  • WebSocket client with ping/pong testing

In Progress (Phase 3):

  • Terminal control (tmux integration)

📋 Planned (Phases 4-9):

  • LLM integration (OpenAI GPT-4)
  • Agent orchestrator
  • Speech-to-Text (Deepgram)
  • Text-to-Speech (OpenAI)
  • Audio streaming
  • UI polish

See IMPLEMENTATION_PLAN.md for complete details.

Environment Variables

OPENAI_API_KEY=your-openai-key-here      # GPT-4 and TTS
DEEPGRAM_API_KEY=your-deepgram-key-here  # Streaming STT
STT_MODEL=whisper-1        # Optional: override to gpt-4o-transcribe, etc.
STT_CONFIDENCE_THRESHOLD=-3.0  # Optional: reject low-confidence clips
STT_DEBUG_AUDIO_DIR=.stt-debug # Optional: persist raw dictation audio for debugging
PASEO_HOME=~/.paseo        # Runtime state directory (agents/, etc.)
PASEO_LISTEN=127.0.0.1:6767  # Listen address (host:port or /path/to/socket)

PASEO_HOME defaults to ~/.paseo and isolates runtime artifacts like agents/. PASEO_LISTEN controls the daemon listen address. For blue/green testing you can run a parallel server without touching production state:

PASEO_HOME=~/.paseo-blue PASEO_LISTEN=127.0.0.1:7777 npm run dev

Tech Stack

  • Server: Express, TypeScript, ws (WebSocket)
  • Client: React 18, Vite, TypeScript
  • Terminal: tmux (via child_process)
  • AI: OpenAI (LLM + TTS), Deepgram (STT)

Testing

Currently manual testing via:

  1. Start servers: npm run dev
  2. Open http://localhost:5173
  3. Test WebSocket connection (green status indicator)
  4. Click "Send Ping" button to test communication

More testing guidance as features are implemented.
