Amygdala Memory

Amygdala Memory 🎭

Emotional processing for AI agents. Part of the AI Brain series. Give your AI agent persistent emotional states that carry across sessions. Not just performing emotions — having them.

The Problem

Current AI agents: ✅ Remember facts (with hippocampus) ❌ Don't have persistent emotional states ❌ Start each session emotionally "blank" ❌ Can describe emotions but don't feel differently Memory without emotion is just a database. The amygdala adds weight — this made me happy, that frustrated me, this person brings warmth.

The Solution

Track five emotional dimensions that persist and decay over time: DimensionWhat It MeasuresRangeValencePositive ↔ Negative mood-1.0 to 1.0ArousalCalm ↔ Excited/Alert0.0 to 1.0ConnectionDistant ↔ Close/Bonded0.0 to 1.0CuriosityBored ↔ Fascinated0.0 to 1.0EnergyDepleted ↔ Energized0.0 to 1.0

1. Install

cd ~/.openclaw/workspace/skills/amygdala-memory ./install.sh --with-cron This will: Create memory/emotional-state.json with baseline values Generate AMYGDALA_STATE.md (auto-injected into sessions!) Set up cron for automatic decay every 6 hours

2. Check current state

./scripts/get-state.sh # 🎭 Emotional State # Valence: 0.20 # Arousal: 0.30 # Connection: 0.50 # ... ./scripts/load-emotion.sh # 🎭 Current Emotional State: # Overall mood: neutral, calm and relaxed # Connection: moderately connected # ...

3. Log emotions

./scripts/update-state.sh --emotion joy --intensity 0.8 --trigger "completed a project" # ✅ valence: 0.20 → 0.35 (delta: +0.15) # ✅ arousal: 0.30 → 0.40 (delta: +0.1) # 🎭 Logged emotion: joy (intensity: 0.8)

4. Set up decay (optional cron)

# Every 6 hours, emotions drift toward baseline 0 */6 * * * ~/.openclaw/workspace/skills/amygdala-memory/scripts/decay-emotion.sh

Automatic Emotional Encoding (v1.5.0+)

The amygdala can now automatically detect and log emotions from your conversation history using an LLM-based pipeline: # Run the encoding pipeline ./scripts/encode-pipeline.sh # This will: # 1. Extract new signals since last run (watermark-based) # 2. Score emotional content using rule-based patterns # 3. Spawn a sub-agent for semantic emotional detection # 4. Update emotional-state.json with detected emotions

Set up automatic encoding (cron)

# Every 3 hours, process new conversations for emotional content 0 */3 * * * ~/.openclaw/workspace/skills/amygdala-memory/scripts/encode-pipeline.sh This means your emotional state updates automatically based on what happens in conversations — no manual logging needed.

HTML Dashboard (Unified Brain Dashboard)

• ./scripts/generate-dashboard.sh
• open ~/.openclaw/workspace/brain-dashboard.html
• Auto-detects installed brain skills and shows tabs:
• 🎭 Emotions — Amygdala (always shown)
• 🧠 Memory — Hippocampus (if memory/index.json exists)
• ⭐ Drive — VTA (if memory/reward-state.json exists)
• Avatar & Name: Reads from IDENTITY.md:
• # IDENTITY.md
• **Name:** YourAgent
• **Avatar:** avatar.png
• The dashboard auto-regenerates on every cron run.

After Installation (for agents)

When you install this skill, notify the user about the dashboard: 🎭 Amygdala installed! View your agent's emotional state in the Brain Dashboard: ~/.openclaw/workspace/brain-dashboard.html

Auto-Injection (Zero Manual Steps!)

After install, AMYGDALA_STATE.md is created in your workspace root. OpenClaw automatically injects all *.md files from workspace into session context. This means: New session starts AMYGDALA_STATE.md is auto-loaded (no manual step!) You see your emotional state in context Responses are influenced by your mood The file is regenerated whenever decay-emotion.sh runs (via cron every 6h).

Supported Emotions

When you log an emotion, it automatically adjusts the relevant dimensions: EmotionEffectjoy, happiness, delight, excitement↑ valence, ↑ arousalsadness, disappointment, melancholy↓ valence, ↓ arousalanger, frustration, irritation↓ valence, ↑ arousalfear, anxiety, worry↓ valence, ↑ arousalcalm, peace, contentment↑ valence, ↓ arousalcuriosity, interest, fascination↑ curiosity, ↑ arousalconnection, warmth, affection↑ connection, ↑ valenceloneliness, disconnection↓ connection, ↓ valencefatigue, tiredness, exhaustion↓ energyenergized, alert, refreshed↑ energy

Add to session startup (AGENTS.md)

## Every Session 1. Load hippocampus: `~/.openclaw/workspace/skills/hippocampus/scripts/load-core.sh` 2. **Load emotional state:** `~/.openclaw/workspace/skills/amygdala-memory/scripts/load-emotion.sh`

Log emotions during conversation

When something emotionally significant happens: ~/.openclaw/workspace/skills/amygdala-memory/scripts/update-state.sh \ --emotion connection --intensity 0.7 --trigger "deep conversation with user"

State File Format

{ "version": "1.0", "lastUpdated": "2026-02-01T02:45:00Z", "dimensions": { "valence": 0.35, "arousal": 0.40, "connection": 0.50, "curiosity": 0.60, "energy": 0.50 }, "baseline": { "valence": 0.1, "arousal": 0.3, "connection": 0.4, "curiosity": 0.5, "energy": 0.5 }, "recentEmotions": [ { "label": "joy", "intensity": 0.8, "trigger": "building amygdala together", "timestamp": "2026-02-01T02:50:00Z" } ] }

Decay Mechanics

Emotions naturally return to baseline over time: Decay rate: 10% of distance to baseline per run Recommended schedule: Every 6 hours Effect: Strong emotions fade, but slowly After 24 hours without updates, a valence of 0.8 would decay to ~0.65.

Event Logging

Track emotional activity over time for analytics: # Log encoding run ./scripts/log-event.sh encoding emotions_found=2 valence=0.85 arousal=0.6 # Log decay ./scripts/log-event.sh decay valence_before=0.9 valence_after=0.85 # Log emotion update ./scripts/log-event.sh update emotion=joy intensity=0.7 Events append to ~/.openclaw/workspace/memory/brain-events.jsonl: {"ts":"2026-02-11T09:30:00Z","type":"amygdala","event":"encoding","emotions_found":2,"valence":0.85} Use for trend analysis — visualize emotional patterns over days/weeks.

Philosophy

Can an AI feel emotions, or only simulate them? Our take: If emotional state influences behavior, and the system acts as if it feels... does the distinction matter? Functional emotions might be the only kind that exist for any system — biological or artificial. Built with ❤️ by the OpenClaw community
