# Hooks Integration - Quick Start

Complete integration between agentic-jujutsu and agentic-flow hooks system.

## 🎯 Overview

This integration enables automatic tracking of all jj operations within agentic-flow workflows:

- ✅ **Auto-tracking**: Every operation logged automatically
- ✅ **AgentDB sync**: Learning from operation history
- ✅ **Multi-agent**: Coordinate multiple agents safely
- ✅ **Conflict-free**: jj's merge capabilities
- ✅ **Type-safe**: Full TypeScript and Rust APIs

## 🚀 Quick Start

### 1. Build the CLI Tool

```bash
cd packages/agentic-jujutsu
cargo build --release --features cli
```

### 2. Basic Usage

```bash
# Pre-task hook
./target/release/jj-agent-hook pre-task \
  --agent-id coder-1 \
  --session-id swarm-001 \
  --description "Implement authentication"

# Post-edit hook
./target/release/jj-agent-hook post-edit \
  --file src/auth.rs \
  --agent-id coder-1 \
  --session-id swarm-001

# Post-task hook
./target/release/jj-agent-hook post-task \
  --agent-id coder-1 \
  --session-id swarm-001
```

### 3. Integration with agentic-flow

```bash
# Use hooks in your workflow
npx claude-flow@alpha hooks pre-task --description "Development task"

# After file edits
npx claude-flow@alpha hooks post-edit --file "src/file.rs"

# After completion
npx claude-flow@alpha hooks post-task --task-id "task-001"
```

## 📊 Hook Lifecycle

```
1. Pre-Task
   ├─ Initialize session
   ├─ Store context
   └─ Sync to AgentDB

2. Work Phase
   ├─ Post-Edit (per file)
   │  ├─ Log operation
   │  ├─ Track changes
   │  └─ Sync to AgentDB
   │
   └─ Conflict Detection
      ├─ Check for conflicts
      └─ Notify coordination

3. Post-Task
   ├─ Gather operations
   ├─ Generate summary
   ├─ Sync to AgentDB
   └─ Clear session
```

## 🔧 Usage Examples

### Rust API

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

#[tokio::main]
async fn main() -> Result<()> {
    // Setup
    let config = JJConfig::default().with_agentdb_sync(true);
    let wrapper = JJWrapper::new(config)?;
    let mut integration = JJHooksIntegration::new(wrapper, true);

    // Create context
    let ctx = HookContext::new(
        "my-agent".to_string(),
        "session-001".to_string(),
        "Implement feature X".to_string(),
    );

    // Pre-task
    integration.on_pre_task(ctx.clone()).await?;

    // Work
    integration.on_post_edit("src/feature.rs", ctx.clone()).await?;
    integration.on_post_edit("tests/test.rs", ctx.clone()).await?;

    // Post-task
    let operations = integration.on_post_task(ctx).await?;
    println!("Logged {} operations", operations.len());

    Ok(())
}
```

### TypeScript API

```typescript
import { createHooksIntegration, withHooks } from '@agentic-flow/jujutsu';

const integration = await createHooksIntegration(
    config,
    'session-001',
    'my-agent',
    true // Enable AgentDB
);

const { result, operations } = await withHooks(
    integration,
    'Implement feature X',
    async (hooks) => {
        await hooks.onPostEdit('src/feature.rs');
        await hooks.onPostEdit('tests/test.rs');
        return { success: true };
    }
);

console.log(`Completed with ${operations.length} operations`);
```

### CLI Usage

```bash
# Enable verbose logging
export JJ_VERBOSE=true

# Enable AgentDB sync
export AGENTDB_SYNC_ENABLED=true
export AGENTDB_SYNC_FILE=./agentdb-episodes.jsonl

# Run hooks
jj-agent-hook pre-task \
  --agent-id coder-1 \
  --session-id swarm-001 \
  --description "Implement auth" \
  --verbose

jj-agent-hook post-edit \
  --file src/auth.rs \
  --agent-id coder-1 \
  --session-id swarm-001 \
  --description "Added login function"

jj-agent-hook post-task \
  --agent-id coder-1 \
  --session-id swarm-001
```

## 🐛 Troubleshooting

### Issue: CLI not found

```bash
# Build with CLI features
cargo build --release --features cli

# Add to PATH
export PATH="$PATH:$(pwd)/target/release"
```

### Issue: AgentDB sync not working

```bash
# Check environment
echo $AGENTDB_SYNC_ENABLED
echo $AGENTDB_SYNC_FILE

# Create file
touch ./agentdb-episodes.jsonl
chmod 644 ./agentdb-episodes.jsonl
```

### Issue: Hooks not executing

```bash
# Test hook manually
jj-agent-hook pre-task \
  --agent-id test \
  --session-id test \
  --description "test" \
  --verbose
```
