## Current Problems

### 1. Setup Complexity Issues

**Problem**: Users face overwhelming choices and complex setup

Current workflow:
```
1. Read documentation about configuration files
2. Choose between multiple configuration formats (TOML/YAML/JSON)
3. Manually configure database URLs, tokens, paths
4. Set performance parameters without guidance
5. Debug connectivity issues manually
6. Handle validation errors with poor error messages
Time to first use: 15-30 minutes for basic setup
```

**User Impact**:
- New users abandon during setup
- Existing users make configuration mistakes
- Support burden from configuration issues
- Poor first impression of tool

### 2. Error Experience Issues

**Problem**: Poor error messages provide no actionable guidance

Current error:
```
"Either Turso URL or redb path must be configured"
```

Better error:
```
"No storage backend configured
💡 Fix: Choose one of these options:
  • Local development: SimpleMode::setup_local()
  • Cloud setup: Configure database.turso_url and database.turso_token
  • Quick start: Run 'do-memory-cli config wizard'
"
```

### 3. Learning Curve Issues

**Problem**: No progressive disclosure of complexity

- Beginners see all options at once
- No recommended defaults for common use cases
- No guided path from simple to advanced configuration

### Root Cause Analysis

**Configuration Complexity**:
- **Historical State**: 403+ lines in `do-memory-cli/src/config.rs`
- **Code Duplication**: 18.6% duplication measured
- **Complex Fallback Logic**: Repeated 3-4 times

**User Friction Points**:
1. Choosing configuration format (TOML/YAML/JSON)
2. Understanding all required parameters
3. Setting up database URLs and authentication
4. Configuring performance parameters without benchmarks
5. Troubleshooting validation errors
6. Understanding error messages

## Design Solution

### Three-Tier Configuration Model

```
TIER 1: Simple Mode (80% of users)
├─ One decision: Database type (Local/Cloud/Memory)
├─ One decision: Performance level (Minimal/Standard/High)
└─ Result: Optimal configuration in 1 call

TIER 2: Wizard Mode (15% of users)
├─ Step-by-step guided setup
├─ Contextual help and suggestions
├─ Real-time validation feedback
└─ Result: Custom configuration with guidance

TIER 3: Advanced Mode (5% of users)
├─ Manual configuration file editing
├─ Full control over all parameters
├─ Advanced validation rules
└─ Result: Fine-tuned configuration
```

### Simple Mode Design

**Decision Matrix**:

```rust
// Simple Mode Decision Matrix
pub enum SimpleSetup {
    // Local development scenarios
    LocalMinimal,    // 30 seconds to setup, < 100MB memory
    LocalStandard,   // 2 minutes to setup, < 1GB memory
    LocalHigh,       // 5 minutes to setup, < 4GB memory

    // Cloud scenarios
    CloudStarter,    // Cloud database, balanced performance
    CloudProduction, // Cloud database, high performance

    // Testing scenarios
    MemoryOnly,      // Instant setup, testing only
}

impl SimpleSetup {
    pub fn for_use_case(use_case: &str) -> Self {
        match use_case {
            "development" => Self::LocalStandard,
            "testing" => Self::MemoryOnly,
            "production" => Self::CloudProduction,
            _ => Self::LocalStandard,
        }
    }
}
```

**One-Call Setup Experience**:

```rust
// CLI Integration for Simple Mode
#[derive(Clap)]
pub enum SimpleCommands {
    /// Quick setup for local development
    Dev {
        /// Performance level (minimal/standard/high)
        #[clap(short, long, default_value = "standard")]
        performance: PerformanceLevel,

        /// Skip validation and just create config
        #[clap(short, long)]
        dry_run: bool,
    },

    /// Quick setup for production
    Prod {
        /// Cloud provider (turso only for now)
        #[clap(short, long, default_value = "turso")]
        provider: String,

        /// Performance level
        #[clap(short, long, default_value = "high")]
        performance: PerformanceLevel,
    },

    /// Quick setup for testing
    Test {
        /// Include sample data
        #[clap(short, long)]
        with_sample_data: bool,
    },
}
```

### Embeddings Configuration

**Structure**:

```rust
/// Embeddings configuration for semantic search
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct EmbeddingsConfig {
    /// Enable semantic embeddings
    pub enabled: bool,
    /// Embedding provider: "local", "openai", "mistral", "azure", or "custom"
    pub provider: String,
    /// Model name or identifier
    pub model: String,
    /// Embedding dimension
    pub dimension: usize,
    /// API key environment variable (e.g., "OPENAI_API_KEY")
    pub api_key_env: Option<String>,
    /// Base URL for custom providers
    pub base_url: Option<String>,
    /// Similarity threshold for search (0.0 - 1.0)
    pub similarity_threshold: f32,
    /// Batch size for embedding generation
    pub batch_size: usize,
    /// Cache embeddings to avoid regeneration
    pub cache_embeddings: bool,
    /// Timeout for embedding requests (seconds)
    pub timeout_seconds: u64,
}
```

**Configuration Example**:

```toml
[embeddings]
enabled = true
provider = "local"
model = "all-MiniLM-L6-v2"
dimension = 384
similarity_threshold = 0.7
batch_size = 10
cache_embeddings = true
timeout_seconds = 30
```

## Implementation Guide

### Configuration Wizard Architecture

**Core Structure**:

```rust
pub struct ConfigWizard {
    current_step: WizardStep,
    config: Config,
    ui: WizardUI,
}

#[derive(Debug, Clone)]
pub enum WizardStep {
    Welcome,
    DatabaseType,
    PerformanceLevel,
    Customize,
    Review,
    Save,
    Complete,
}
```

### Step 1: Welcome

**Implementation**:
```rust
async fn step_welcome(&mut self) -> Result<(), ConfigError> {
    println!("\n🧠 Welcome to Memory CLI Configuration!");
    println!("=====================================");
    println!("This wizard will help you set up Memory CLI in just a few steps.");
    println!("You can always re-run this wizard or edit config file later.");
    println!();
    Ok(())
}
```

### Step 2: Database Type Selection

**Implementation**:
```rust
async fn step_database_type(&mut self) -> Result<(), ConfigError> {
    println!("\n📊 Step 1 of 3: Database Type");
    println!("------------------------------");
    println!("Choose how you want to store your memory data:");
    println!();
    println!("[1] 📁 Local Database (SQLite)");
    println!("    • Good for: Development, personal use, small teams");
    println!("    • Benefits: Fast, private, no external dependencies");
    println!("    • Storage: Local file on your computer");
    println!();
    println!("[2] ☁️  Cloud Database (Turso)");
    println!("    • Good for: Production, collaboration, backups");
    println!("    • Benefits: Accessible from anywhere, automatic backups");
    println!("    • Storage: Cloud-hosted database");
    println!();
    println!("[3] 🧠 Memory Only (Temporary)");
    println!("    • Good for: Testing, learning, temporary data");
    println!("    • Benefits: Instant setup, no storage needed");
    println!("    • Storage: In-memory (lost when program closes)");

    let choice = self.ui.prompt_choice(1, 3)?;

    match choice {
        1 => {
            self.config.database.turso_url = None;
            self.config.database.turso_token = None;
            self.config.database.redb_path = Some("./data/memory.redb".to_string());
            println!("✅ Local database selected");
        }
        2 => {
            self.config.database.turso_url = Some("https://your-db.turso.io".to_string());
            self.config.database.redb_path = Some("./data/memory.cache.redb".to_string());
            println!("✅ Cloud database selected");
            println!("💡 You'll need to configure your Turso database URL and token");
        }
        3 => {
            self.config.database.turso_url = None;
            self.config.database.turso_token = None;
            self.config.database.redb_path = None;
            println!("✅ Memory-only mode selected");
        }
        _ => unreachable!(),
    }

    Ok(())
}
```

### Step 3: Performance Level Selection

**Implementation**:
```rust
async fn step_performance_level(&mut self) -> Result<(), ConfigError> {
    println!("\n⚡ Step 2 of 3: Performance Level");
    println!("---------------------------------");
    println!("Choose performance level that matches your needs:");
    println!();

    // Adjust options based on database type
    if self.config.database.turso_url.is_some() {
        // Cloud database
        println!("[1] 🐌 Minimal");
        println!("    • Memory: < 100MB");
        println!("    • Episodes: < 1,000");
        println!("    • Good for: Light usage, small projects");
        println!();
        println!("[2] 🏃 Standard");
        println!("    • Memory: < 500MB");
        println!("    • Episodes: < 10,000");
        println!("    • Good for: Most use cases");
        println!();
        println!("[3] 🚀 High");
        println!("    • Memory: < 2GB");
        println!("    • Episodes: < 100,000");
        println!("    • Good for: Heavy usage, large projects");
    } else {
        // Local or memory-only
        println!("[1] 🐌 Minimal");
        println!("    • Memory: < 50MB");
        println!("    • Episodes: < 100");
        println!("    • Good for: Testing, quick experiments");
        println!();
        println!("[2] 🏃 Standard");
        println!("    • Memory: < 200MB");
        println!("    • Episodes: < 1,000");
        println!("    • Good for: Development, personal projects");
        println!();
        println!("[3] 🚀 High");
        println!("    • Memory: < 1GB");
        println!("    • Episodes: < 10,000");
        println!("    • Good for: Production use, large datasets");
    }

    let choice = self.ui.prompt_choice(1, 3)?;

    let (max_cache, pool_size) = match choice {
        1 => (100, 2),
        2 => (1000, 10),
        3 => (10000, 20),
        _ => unreachable!(),
    };

    self.config.storage.max_episodes_cache = max_cache;
    self.config.storage.pool_size = pool_size;

    let level_name = match choice {
        1 => "Minimal",
        2 => "Standard",
        3 => "High",
        _ => unreachable!(),
    };

    println!("✅ {} performance level selected", level_name);
    Ok(())
}
```

### Complete Wizard Flow

**Main wizard runner**:

## Migration Guide

### Automatic Migration Detection

**Migration Assistant**:

```rust
pub struct ConfigMigrationAssistant {
    old_config_path: Option<PathBuf>,
    new_config_path: PathBuf,
}

impl ConfigMigrationAssistant {
    pub async fn check_and_migrate() -> Result<bool> {
        // Check for old configuration files
        let old_paths = vec![
            "do-memory-cli.toml",
            ".do-memory-cli.toml",
            "do-memory-cli.json",

                }
            }
        }

        // Save new configuration
        let new_path = "do-memory-cli.toml";
        let content = toml::to_string_pretty(&new_config)?;
        std::fs::write(new_path, content)?;
