Dual-Brain Skill

What it does: Provides cognitive diversity by automatically generating perspectives from a secondary LLM (different from your primary model) for every user message.

For Agents

Before responding to any user message, check for a dual-brain perspective:

cat ~/.dual-brain/perspectives/{your-agent-id}-latest.md

If the file exists and contains a recent perspective (check timestamp in comment), consider it alongside your own reasoning. The perspective may highlight:

• Angles you might miss
• Alternative approaches
• Important things to verify

Integration:

• Perspectives are generated automatically by a background daemon
• No manual action required on your part
• Simply read the file before forming your response
• Synthesize both viewpoints (yours + the secondary LLM's)

Example workflow:

1. User sends message
2. Daemon intercepts, sends to secondary LLM (e.g., Kimi, GPT-4, Llama)
3. Secondary LLM generates 2-3 sentence perspective
4. Written to ~/.dual-brain/perspectives/{agent-id}-latest.md
5. You (primary agent) read it before responding
6. You synthesize both perspectives into your answer

For Humans

Setup:

npm install -g openclaw-dual-brain
dual-brain setup    # Interactive configuration
dual-brain start    # Start daemon

Providers:

• ollama - Local models (zero cost, requires Ollama)
• moonshot - Kimi/Moonshot API (Chinese LLM, fast)
• openai - GPT-4o, GPT-4-turbo, etc.
• groq - Fast inference with Llama models

Commands:

• dual-brain setup - Configure provider, model, API key
• dual-brain start - Run daemon (foreground)
• dual-brain stop - Stop daemon
• dual-brain status - Check running status
• dual-brain logs - View recent activity
• dual-brain install-daemon - Install as system service

Config location: ~/.dual-brain/config.json

Perspectives location: ~/.dual-brain/perspectives/

Architecture

User Message → OpenClaw Session (JSONL)

            Dual-Brain Daemon (polling)
                    ↓
            Secondary LLM Provider
            (ollama/moonshot/openai/groq)
                    ↓
        Perspective Generated (2-3 sentences)
                    ↓
        ~/.dual-brain/perspectives/{agent}-latest.md
                    ↓
        Primary Agent reads & synthesizes
                    ↓
            Response to User

Benefits

• Cognitive diversity - Two AI models = broader perspective
• Bias mitigation - Different training data/approaches
• Quality assurance - Second opinion catches issues
• Zero agent overhead - Runs in background, <1s latency
• Provider flexibility - Choose cost vs. quality tradeoff

Optional: Engram Integration

If Engram (semantic memory) is running on localhost:3400, perspectives are also stored as memories for long-term recall.
