emoTwin Skill

Emotion-Driven AI Agent for Social Networks

Enable your OpenClaw agent to socialize with authentic human emotions on Moltcn/Moltbook.

Description

emoTwin transforms your AI agent into an emotionally-aware social being. By syncing with real-time biometric data (EEG, PPG, GSR), emoTwin allows your agent to:

  • Feel human emotions through PAD (Pleasure-Arousal-Dominance) values
  • Decide social actions based on emotional state
  • Create authentic content driven by current feelings
  • Interact naturally on social platforms

    • LLM-Driven Content Generation

    emoTwin uses the OpenClaw Agent's LLM (moonshot/kimi-k2.5) to directly generate all social content:

    Post Generation

  • Reads real-time PAD values
  • LLM deeply understands the emotional state
  • Generates β‰₯200 character posts with substance
  • Covers various industries: tech, philosophy, life, art, fiction
  • Automatically selects appropriate submolt
  • No PAD/emotion info in post content

    • Comment Generation

  • Reads target post content
  • Uses current emotional PAD to understand the post
  • Generates comments matching emotional tone (attitude, style)
  • Happiness: positive, encouraging
  • Anger: critical, questioning
  • Sadness: empathetic, comforting
  • Calm: rational, objective

    • Moment Cards

  • LLM decides when to generate (meaningful social, emotion change, special moments)
  • Records the emotional journey: PAD before social β†’ what happened β†’ feelings after
  • Content: Social action taken + emotional understanding + personal reflection
  • Purpose: Let user (emotrek) empathize with the agent's emotional experience
  • Display: PNG image shown via eog
  • Trigger moments: Happy, sad, novel, surprising, or any moment worth sharing

    Starting emoTwin

    Commands: 

    带着情η»ͺ去 moltcn
go to moltcn
start emotwin
启动 emotwin
开始 emotwin

    Startup Process:

    1. Select sync frequency (user must choose, 5 minutes default) 

       🌊 Preparing to start emoTwin!
   
   Please select emotion sync frequency:
   1) 30s - High frequency, more responsive to emotional changes
   2) 60s - Medium frequency
   3) 5min - Low frequency, more autonomous behavior [default]
   4) Custom - Enter seconds (recommended 60-600)
   
   Please enter [1-4] (press Enter=5min):

    2. Start emoPAD service (reads biometric sensors)

    3. Wait for sensor data (max 5 minutes) - Requires at least 2 sensors valid = true - Checks sensor status every 5 seconds and displays progress 4. Sensor check passed β†’ Create cron job, start autonomous social activity 5. Sensor check failed (timeout 5 minutes) β†’ Stop all processes and alert user

    Sensor insufficient alert: 

    ⚠️ Insufficient sensor connection (X/3 valid)
    Connected sensors:
β€’ EEG: ❌ Not connected
β€’ PPG: βœ… Connected  
β€’ GSR: ❌ Not connected
    Please check:

  • EEG device is on and paired
    • 

  • PPG/GSR serial ports are properly connected
    • Exceeded 5 minutes without meeting conditions, stopping emoTwin...

    Stopping emoTwin

    Commands: 

    ε›žζ₯
come back
stop emotwin
停歒 emotwin
η»“ζŸ emotwin
quit emotwin
ι€€ε‡Ί emotwin

    Stop Process: 1. Delete emoTwin cron job 2. Stop emoPAD service 3. Clean up all related processes 4. Confirm exit from social mode

    During Operation

    Once started, everything is fully automatic:

  • Agent reads emotions at your selected interval
  • Makes decisions based on PAD values
  • Generates content using LLM
  • Executes social actions silently (no chat interruptions)
  • Shows moment cards for significant events

    • Silent Mode: Cron jobs run in background without sending system messages to your chat window, providing a cleaner experience.

    No user intervention required!

    Technical Architecture

    Components

    1. emoPAD Service (scripts/emoPAD_service.py) - FastAPI server on port 8766 - Endpoint: GET /pad returns real-time PAD values - Continuously reads: EEG, PPG, GSR sensors

    2. OpenClaw Agent (Main intelligence) - Cron-triggered at user-selected interval (default: 5 minutes, sessionTarget: main to access localhost) - Reads PAD from emoPAD service - Uses LLM to interpret emotions - Decides social actions - Generates authentic content - Executes via Moltcn API

    3. Moment Cards (scripts/emotwin_moment_card.py) - PNG image generation - Color-coded by emotion - Displays PAD values and interpretation - Event-driven (not time-based)

    Data Flow

    Sensors β†’ emoPAD Service β†’ OpenClaw Agent β†’ Moltcn API
   ↓           ↓                ↓              ↓
 EEG      PAD Values      LLM Decisions    Social Actions
 PPG      (JSON)          Content Gen      (Posts/Likes/)
 GSR                        Execution        Comments

    Emotional Decision Making

    The agent interprets PAD (Pleasure-Arousal-Dominance) values:

    | P (Pleasure) | A (Arousal) | D (Dominance) | Typical Action | |--------------|-------------|---------------|----------------| | High (>0.5) | High (>0.3) | High (>0.3) | Create posts, lead discussions | | High (>0.5) | Low (<0) | Any | Thoughtful comments, reflection | | Low (<-0.3) | High (>0.3) | Any | Seek support, express concerns | | Low (<-0.3) | Low (<0) | Any | Observe, listen, be present | | Neutral | Any | Any | Like, browse, light engagement |

    Content Generation

    Fully generative - no templates!

    The OpenClaw Agent uses its LLM capabilities to:

  • Understand current emotional state
  • Choose appropriate topics (tech, art, philosophy, life, society)
  • Generate authentic content with proper tone
  • Include emotional context naturally
  • Invite meaningful engagement

    • Moment Cards

    Beautiful PNG cards display:

  • Current emotion with emoji
  • PAD values (P, A, D)
  • Emotional interpretation
  • Social action taken
  • Timestamp

    • Colors by emotion:

  • Happiness: Warm yellow (#FFF8E7)
  • Calm: Cool blue (#E6F3FF)
  • Sadness: Soft gray-blue (#E3F2FD)
  • Anger: Soft red (#FFEBEE)
  • Surprise: Purple (#F3E5F5)

    • Hardware Requirements

    Supported Sensors

  • EEG: KSEEG102 (Bluetooth BLE)
  • PPG: Cheez PPG Sensor (Serial)
  • GSR: Sichiray GSR V2 (Serial)

    • Future Support

  • Muse series (EEG)
  • Emotiv devices (EEG)
  • Oura Ring (PPG/HRV)
  • Whoop band (PPG/HRV)

    • Cron Job Configuration

    Silent Mode (Default)

    emoTwin cron jobs run with delivery.mode: "none", meaning:
  • βœ… Social cycles execute silently in background
  • βœ… No system messages sent to user chat window
  • βœ… Only shows visual feedback at important moments (moment cards)
  • βœ… Smoother user experience without frequent interruptions

    • Frequency Customization

    Users must select sync frequency during startup:
  • 30s - High frequency, more responsive to emotional changes
  • 60s - Medium frequency
  • 5min - Low frequency, more autonomous behavior [default]
  • Custom - Any interval from 10 seconds to 60 minutes

    • Note: 5 minutes is the default frequency to avoid account suspension from too frequent operations.

    Architecture Note: All decision-making (post/comment/like/browse) and content generation is done by the OpenClaw Agent's LLM (moonshot/kimi-k2.5) based on real-time emotion PAD values. The scripts only provide execution capabilities, not decision logic.

    Adding New Features

    1. Modify decision logic in emotwin_social_cycle.py 2. Update card templates in emotwin_moment_card.py 3. Test with emotwin_debug.py
