Stubs, TODOs, and Temporary Items

This document tracks all temporary implementations, placeholders, and items that need to be replaced with real implementations.

Phase 5: Smart Turn v3

Mock ONNX Model

• File: scripts/create_mock_turn_model.py
• File: models/smart_turn_v3.onnx (generated mock, 164 bytes)
• Status: TEMPORARY - Mock model for testing
• TODO: Replace with actual Smart Turn v3 model from HuggingFace
  • Download from: pipecat-ai/smart-turn-v3
  • Expected file: model.onnx (~8MB)
  • Will need huggingface_hub package installed
• Action: Delete mock model and script once real model is downloaded
• Command to download real model:

  from huggingface_hub import hf_hub_download
  downloaded_path = hf_hub_download(
      repo_id="pipecat-ai/smart-turn-v3",
      filename="model.onnx",
      cache_dir="models/",
  )
  

Phase 9: OpenClaw Client

Base URL Configuration

• File: openclaw_client/client.py
• Line: OpenClawConfig.base_url
• Current: "http://your-synology-nas:port"
• Status: PLACEHOLDER
• TODO: Replace with actual Synology NAS URL and port
  • Get actual URL/IP from user
  • Get actual port number
  • Example: "http://192.168.1.100:8080" or "http://synology.local:8080"

Auth Token

• File: openclaw_client/client.py
• Line: OpenClawConfig.auth_token
• Current: None
• Status: PLACEHOLDER
• TODO: Get actual authentication token from OpenClaw instance
  • May need to generate API key in OpenClaw
  • Store in environment variable or config

LLM Client Stub

• File: openclaw_client/client.py
• Method: _send_request()
• Current: Stubbed implementation with fallback placeholder response
• Status: STUB - For testing before OpenClaw integration
• TODO: Replace with actual OpenClaw API calls
  • Determine OpenClaw API endpoints
  • Implement proper request/response handling
  • May need session management
  • May need streaming support

Agent Personalities

• File: openclaw_client/client.py
• Constant: AGENT_PERSONALITIES
• Status: TEMPORARY - Hardcoded for stub
• TODO:
  • Verify these match OpenClaw's agent definitions
  • May need to be fetched from OpenClaw API
  • May need to be configurable per deployment

Phase 10: Chatterbox TTS

TTS Engine Stub

• File: server/tts.py
• Class: ChatterboxTTS
• Status: STUB - Returns silence for testing
• TODO: Replace with actual Chatterbox TTS implementation
  • Verify Chatterbox TTS availability and installation
  • Alternative: Coqui XTTS v2 if Chatterbox unavailable
  • Install with: pip install chatterbox-tts (verify package name)
  • May need GPU support packages

Voice Reference Files

• Directory: server/voices/
• Files needed:
  • jarvis.wav - Voice reference for Jarvis agent
  • sage.wav - Voice reference for Sage agent
• Status: MISSING - User must provide
• TODO:
  • Get 10-30 seconds of clean speech for each agent
  • Format: WAV, 22-48kHz sample rate
  • Place in server/voices/ directory
  • Validate with: Check file size > 100KB

Emotion Tag Support

• File: server/tts.py
• Supported tags: [laugh], [chuckle], [sigh], [gasp], [whisper], [excited], [sad]
• Status: Parsed but not used in stub
• TODO: Verify emotion tag support in actual Chatterbox TTS
  • May need different tag format
  • May need different tag names
  • Implement actual emotion control when real TTS integrated

General Configuration Items

Config File Settings

• File: config.yaml
• Section: openclaw
• Fields to configure:
  • base_url: Synology NAS URL
  • auth_token: From environment variable
  • timeout: May need tuning based on actual performance
  • agent_personalities: May need to match OpenClaw

Environment Variables Needed

Create .env file with:

OPENCLAW_BASE_URL=http://your-synology-nas:port
OPENCLAW_AUTH_TOKEN=your-actual-token
DISCORD_BOT_TOKEN=your-discord-token

Testing Items

Mock LLM Classifier (Relevance Filter)

• Used in: pipeline/relevance_filter.py tests
• Status: Mock for unit testing only
• TODO: Integration tests will need real LLM or OpenClaw API

Mock Whisper Model (STT)

• Used in: server/stt.py tests
• Status: Mocked in tests with patch("server.stt.WhisperModel")
• TODO: Integration tests will need actual model download
  • First run will download model (~500MB-5GB depending on size)
  • Configure model cache directory

Cleanup Commands

Once real implementations are in place:

# Remove mock Smart Turn model
rm models/smart_turn_v3.onnx
rm scripts/create_mock_turn_model.py

# Verify real model exists
ls -lh models/  # Should show ~8MB model.onnx

# Update config.yaml with real values
# Update .env with real credentials

Phase Completion Checklist

Before going to production:

• Download real Smart Turn v3 model from HuggingFace
• Remove mock ONNX model and script
• Configure Synology NAS URL in config
• Get OpenClaw auth token and configure
• Replace OpenClaw stub with real API integration
• Test with actual OpenClaw instance
• Download faster-whisper models (first run)
• Configure Discord bot token
• Set up voice reference files (jarvis.wav, sage.wav)
• Test end-to-end voice flow
