## 🚀 Usage Examples

### 1. Basic Jujutsu Operations

```rust
use agentic_jujutsu::{JJWrapper, JJConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let jj = JJWrapper::new()?;

    let status = jj.status().await?;
    println!("{}", status.stdout);

    jj.describe("Implement feature").await?;

    Ok(())
}
```

### 2. MCP Integration

```rust
use agentic_jujutsu::{
    AgentDBSync,
    mcp::MCPClientConfig
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Connect to MCP server
    let mcp_config = MCPClientConfig::stdio();
    let agentdb = AgentDBSync::with_mcp(true, mcp_config).await?;

    // Store pattern
    agentdb.store_episode(&episode).await?;

    // Search similar
    let similar = agentdb.query_similar_operations("task", 5).await?;

    Ok(())
}
```

### 3. Hooks Integration

```rust
use agentic_jujutsu::{JJHooksIntegration, HookContext};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let jj = JJWrapper::new()?;
    let mut hooks = JJHooksIntegration::new(jj, true);

    let ctx = HookContext::new(
        "agent-1".to_string(),
        "session-001".to_string(),
        "Implement feature".to_string()
    );

    hooks.on_pre_task(ctx.clone()).await?;
    hooks.on_post_edit("file.rs", ctx.clone()).await?;
    hooks.on_post_task(ctx).await?;

    Ok(())
}
```

### 4. CLI Tool

```bash
# Pre-task hook
jj-agent-hook pre-task \
  --agent-id agent-1 \
  --session-id session-001 \
  --description "Implement feature" \
  --enable-agentdb

# Post-edit hook
jj-agent-hook post-edit \
  --file src/main.rs \
  --agent-id agent-1 \
  --session-id session-001

# Post-task hook
jj-agent-hook post-task \
  --agent-id agent-1 \
  --session-id session-001
```

## 🎓 Key Design Decisions

### 1. Dual Transport Architecture
**Decision:** Support both stdio and SSE transports
**Rationale:** Cover local CLI tools (stdio) and web/remote clients (SSE)
**Benefit:** Same API works everywhere with just config change

### 2. Fallback to Logging
**Decision:** Gracefully degrade when MCP server unavailable
**Rationale:** Package remains useful without MCP infrastructure
**Benefit:** No hard dependency on external services

### 3. Optional MCP Feature
**Decision:** Make MCP an optional cargo feature
**Rationale:** Not all users need MCP; reduces binary size
**Benefit:** Lean builds with `--no-default-features`

### 4. Type-Safe Protocol
**Decision:** Strong typing for all MCP types
**Rationale:** Catch errors at compile time
**Benefit:** Clear API, good IDE support, fewer runtime bugs

### 5. Security First
**Decision:** Input validation on all external inputs
**Rationale:** Prevent injection attacks
**Benefit:** Production-grade security hardening
