## Building Your First AI Memory System

> Let's create a conversational AI that remembers and learns from interactions. This example demonstrates core OrKa features in action.

### Step 1: Create the Workflow

For conversational AI with memory, use the enhanced memory validation example:

```bash
cp examples/memory_validation_routing_and_write.yml conversational-ai.yml
```

This example demonstrates:
- Memory-first approach with intelligent fallback
- Context-aware memory search with conversation continuity
- Automatic memory decay and lifecycle management
- Vector search with HNSW indexing for 100x performance

> **See the full workflow**: [`examples/memory_validation_routing_and_write.yml`](examples/memory_validation_routing_and_write.yml)

### Step 2: Run and Monitor

```bash
# Start the conversation
orka run ./conversational-ai.yml "Hello, I'm working on a machine learning project"

# Continue the conversation (it will remember context)
orka run ./conversational-ai.yml "What algorithms would you recommend for image classification?"

# Monitor memory performance in real-time
orka memory watch
```

You'll see a professional dashboard like this:
```text
┌─────────────────────────────────────────────────────────────┐
│ OrKa Memory Dashboard - 14:23:45 | Backend: redisstack     │
├─────────────────────────────────────────────────────────────┤
│ 🔧 Backend: redisstack (HNSW)  ⚡ Decay: ✅ Enabled        │
│ 📊 Memories: 1,247            📝 Active: 1,224             │
│ 🚀 HNSW Performance: 1,203     Avg: 2.1ms | Hybrid: 856   │
│ 🧠 Memory Types: Short: 423    💾 Long: 801 | 🔥 Recent   │
└─────────────────────────────────────────────────────────────┘
```

### Step 3: Verify Memory Learning

```bash
# Check what the AI remembers about you
orka memory stats

# Search specific memories
redis-cli FT.SEARCH orka:mem:idx "@namespace:user_queries machine learning" LIMIT 0 5
```

## 🧠 Memory Presets - Cognitive AI Architecture

**NEW in v0.9.2**: Simplified memory configuration based on Marvin Minsky's cognitive science principles with **operation-aware smart defaults**.

### Quick Memory Configuration

Instead of complex memory decay rules, just specify a cognitive memory type and operation. The system **automatically applies optimized defaults** for read vs write operations:

```yaml
- id: my_memory_agent
  type: memory
  memory_preset: "episodic"          # Cognitive memory type
  config:
    operation: read                  # 🎯 Auto-applies episodic READ defaults!
    namespace: conversations         # (similarity_threshold=0.6, vector_weight=0.7, etc.)
  prompt: "Find: {{ input }}"

- id: my_memory_writer
  type: memory
  memory_preset: "episodic"          # Same preset, different operation
  config:
    operation: write                 # 🎯 Auto-applies episodic WRITE defaults!
    namespace: conversations         # (vector=true, optimized indexing, etc.)
  prompt: "Store: {{ input }}"
```

### Available Memory Presets (Operation-Aware)

Each preset automatically provides **different optimized defaults** for read vs write operations:

| Preset | Retention | Read Defaults | Write Defaults | Use Case |
|--------|-----------|---------------|----------------|----------|
| **`sensory`** | 15 minutes | Fast retrieval, high precision | Minimal indexing | IoT sensors, live feeds |
| **`working`** | 4 hours | Context-aware search | Session optimization | Current task context |
| **`episodic`** | 7 days | Conversational context | Rich metadata | Conversations, user interactions |
| **`semantic`** | 30 days | Knowledge matching | Knowledge optimization | Documentation, facts |
| **`procedural`** | 90 days | Pattern recognition | Process indexing | Workflows, procedures |
| **`meta`** | 365 days | System analysis | Performance optimization | Metrics, long-term trends |

### Complete Examples

```bash
# Try the enhanced operation-aware presets
cp examples/enhanced_memory_presets_demo.yml my-cognitive-ai.yml
orka run my-cognitive-ai.yml "How does machine learning work?"

# See all 6 cognitive memory types in action
cp examples/memory_presets_showcase.yml showcase.yml
orka run showcase.yml "Hello, I'm learning about AI"

# Simple demo with smart defaults
cp examples/simple_memory_preset_demo.yml quick-demo.yml
orka run quick-demo.yml "Test cognitive memory"
```

### 🎯 Smart Defaults in Action

**Before (Complex Manual Configuration):**
```yaml
- id: memory_reader
  type: memory
  config:
    operation: read
    limit: 8
    similarity_threshold: 0.6
    enable_vector_search: true
    enable_temporal_ranking: true
    temporal_weight: 0.3
    text_weight: 0.3
    vector_weight: 0.7
    enable_hybrid_search: true
    ef_runtime: 10
    # ... 15+ more parameters!
```

**After (Smart Preset Configuration):**
```yaml
- id: memory_reader
  type: memory
  memory_preset: "episodic"  # 🎯 ALL defaults applied automatically!
  config:
    operation: read
    namespace: conversations
    # Only specify custom overrides if needed
```

**Benefits:**
- ✅ **One-line configuration** - No complex decay rules
- ✅ **Cognitive science foundation** - Based on established memory theory
- ✅ **Optimized performance** - Each preset tuned for its use case
- ✅ **Zero breaking changes** - Works with existing configurations

## 🐛 Troubleshooting

### Common Issues and Quick Fixes

| Issue | Quick Fix |
|-------|-----------|
| `"unknown command 'FT.CREATE'"` | You're using basic Redis. Install RedisStack: `docker run -d -p 6380:6380 redis/redis-stack:latest` |
| `"Cannot connect to Redis"` | Check Redis is running: `redis-cli ping` |
| Memory search returns no results | Check vector indexing: `redis-cli FT._LIST` and see [Debugging Guide](./docs/DEBUGGING.md) |
| Slow performance | Verify RedisStack HNSW: `orka memory configure` |
| Out of memory errors | Run cleanup: `orka memory cleanup` |
| TTL mismatch (0.1h vs 2h) | Environment variables override YAML - see [Configuration Guide](./docs/CONFIGURATION.md) |
| FT.SEARCH syntax errors | Check query syntax in [Components Guide](./docs/COMPONENTS.md#shared-memory-reader) |

### Performance Optimization

```bash
# Check current performance
orka memory watch

# Optimize HNSW index
redis-cli FT.CONFIG SET FORK_GC_CLEAN_THRESHOLD 100

# Monitor Redis memory usage
redis-cli INFO memory
```
