* fix(server): stop short start gates from undercutting provider startup budgets

Agent creation still failed on contended cold starts after #3578, because two
shorter gates on the same path fire before the event-stream readiness budget can
apply. A traced creation reached session.create twelve seconds in, past the 10s
session.create gate, and the agent was then killed by a bare "timeout" at fifteen
seconds from AGENT_RUN_START_TIMEOUT_MS while the SSE connect was still running.

A run-start bound of 15s wraps a path that is deliberately allowed 30s, so the
outer gate always wins and the inner budget is unreachable.

Give session.create the shared OPENCODE_SERVER_STARTUP_TIMEOUT_MS budget, since
creating the first session for a directory is part of OpenCode coming up, and
derive its error message from the constant instead of hardcoding "10s". Raise
AGENT_RUN_START_TIMEOUT_MS to 60s with a comment recording that it must stay
above the slowest provider startup budget; it stays a literal because that module
is provider-agnostic.

Related to #3571.

* test(server): drive the run start budget through a real AgentManager

The run start boundary tests replaced AgentManager.waitForAgentRunStart with a
bare timer, so they never exercised the production run-state transition or the
agent_state subscription the real wait depends on. That path could regress while
the tests stayed green.

Build the scenario on a real AgentManager with a provider session that holds its
turn start open for a configurable span, so pendingRun.started, the lifecycle
change to "running", and the agent_state notification are what the wait actually
observes. Budgets stay independent literals and the settled-before/after
assertions are unchanged.

* fix(server): describe agent run start timeouts

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.
