* Let readFile callers disable the request timeout readFile resolves only when FileEnd arrives, so the default 60 s request timeout bounds the whole transfer. A large file over a slow relay fails before it finishes even though every chunk is arriving. Thread an optional timeout through requestFileExplorer; 0 disables the timer, as the workspace.create request already does, and a dead connection still rejects on disconnect. The relay e2e case reads a 1 MiB file through a real daemon and a local relay with timeout 0 and compares SHA-256 digests with the source. * Reject a binary file transfer whose byte count differs from FileBegin.size concatByteChunks allocated FileBegin.size bytes and copied the chunks in: a short transfer resolved as a zero-padded file, and a long one threw a RangeError inside the transport callback and left the request pending. Count the received bytes at FileEnd and reject the read when they differ from the announced size. * Download files over the session socket when no direct connection is active The download store only knew the HTTP token route and picked the first directTcp connection in the host profile, whatever connection the host runtime was using. A relay-only host has none, so every download ended in "Download host is unavailable." (#543). SSH, socket and pipe hosts failed the same way, and a stale directTcp entry won over a working relay (#3753). Choose the transport from the active connection: directTcp keeps the HTTP token download unchanged; anything else reads the file over the session socket with the binary frames previews already use, then hands the bytes to the browser's download manager on web and Electron or writes them to the cache directory and offers the share sheet on native. Files over 64 MiB are refused before any byte moves, using the existing fileTooLarge string, and a daemon response without content fails instead of saving an empty file. * fix(app): enforce the session download size limit during the read The token size is sampled before the file is read. Pass the download byte budget through the actual read so a changed file cannot bypass the in-memory limit.

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:
- Start servers:
npm run dev - Open http://localhost:5173
- Test WebSocket connection (green status indicator)
- Click "Send Ping" button to test communication
More testing guidance as features are implemented.
