## Advanced Usage

### Programmatic API

```javascript
const { Orchestrator, TaskManager } = require('@papaoloba/nightly-code-orchestrator');

// Create orchestrator instance
const orchestrator = new Orchestrator({
  configPath: 'custom-config.yaml',
  tasksPath: 'custom-tasks.yaml',
  maxDuration: 14400  // 4 hours
});

// Run session
orchestrator.run()
  .then(result => {
    console.log(`Session completed: ${result.completedTasks}/${result.totalTasks} tasks`);
  })
  .catch(error => {
    console.error('Session failed:', error);
  });

// Work with tasks directly
const taskManager = new TaskManager();
const tasks = await taskManager.loadTasks();
const ordered = await taskManager.resolveDependencies(tasks);
```

### Automatic Code Improvements

When all scheduled tasks complete successfully but time remains in the session, the orchestrator automatically triggers general code improvement tasks. This feature maximizes the value of your 8-hour coding sessions.

#### How It Works

1. **Automatic Trigger**: After all tasks complete, if 5+ minutes remain in session
2. **Intelligent Selection**: Uses SuperClaude `/sc:improve` command when available, falls back to standard improvement prompts
3. **Quality Focus**: Automatically focuses on code quality, performance, documentation, and security
4. **Safe Execution**: Includes validation and rollback if improvements fail
5. **Git Integration**: Commits improvements with automatic tagging

#### SuperClaude Integration

When SuperClaude is enabled, automatic improvements use the optimized command:

```bash
/sc:improve --scope project --focus quality --iterative --validate
```

This leverages the SuperClaude framework's intelligent analysis and improvement patterns.

#### Configuration

Automatic improvements can be controlled via configuration:

```yaml
# nightly-code.yaml
session:
  max_duration: 28800  # 8 hours
  auto_improvements: true  # Enable automatic improvements (default: true)
  min_improvement_time: 300  # Minimum time required (5 minutes default)

superclaude:
  enabled: true  # Enable SuperClaude for optimized improvements
```

#### Dry Run Mode

In dry run mode, automatic improvements are logged but not executed:

```bash
npx nightly-code --dry-run
# Shows what improvements would be made without executing them
```

### Custom Validation Scripts

Create custom validation scripts for specific requirements:

```javascript
// scripts/validate-auth.js
const { spawn } = require('child_process');

async function validateAuth() {
  console.log('Running authentication validation...');
  
  // Run security audit
  const audit = spawn('npm', ['audit', '--audit-level', 'high']);
  await new Promise((resolve, reject) => {
    audit.on('close', code => code === 0 ? resolve() : reject());
  });
  
  // Run auth-specific tests
  const tests = spawn('npm', ['test', '--', '--grep', 'auth']);
  await new Promise((resolve, reject) => {
    tests.on('close', code => code === 0 ? resolve() : reject());
  });
  
  console.log('Authentication validation passed!');
}

validateAuth().catch(error => {
  console.error('Validation failed:', error);
  process.exit(1);
});
```

```

## Git Integration and Commit Convention

### Commit Message Convention

Nightly Code uses a structured commit message convention for tracking task completion. This provides better integration with standard git workflows and improved searchability.

#### Convention Format

```
<type>(<scope>): <description> [task:<task-id>]

<body>

Task-ID: <task-id>
Task-Title: <full task title>
Task-Type: <feature|bugfix|refactor|test|docs>
Task-Status: completed
Task-Duration: <duration in seconds>
Task-Session: <session-id>
Task-Date: <ISO timestamp>
```

#### Example Commits

**Single Commit Task:**
```
feat(auth): implement user login [task:auth-001]

Implemented JWT-based authentication with refresh tokens.

Task-ID: auth-001
Task-Title: Implement user authentication system
Task-Type: feature
Task-Status: completed
Task-Duration: 3600
Task-Session: session-2024-01-20-120000
Task-Date: 2024-01-20T12:00:00Z
```

**Multi-Commit Task:**
```
# Progress commits
feat(ui): add dashboard layout [task:ui-005] [1/3]
feat(ui): implement dashboard widgets [task:ui-005] [2/3]

# Final commit
feat(ui): complete dashboard implementation [task:ui-005] [3/3]

Finalized dashboard with all widgets and responsive design.

Task-ID: ui-005
Task-Title: Create user dashboard with analytics widgets
Task-Type: feature
Task-Status: completed
Task-Duration: 7200
Task-Session: session-2024-01-20-090000
Task-Date: 2024-01-20T11:00:00Z
```

### Finding Task Commits

```bash
# Find all task completions
git log --grep="\[task:" --oneline

# Find specific task
git log --grep="\[task:auth-001\]"

# List completed tasks with details
git log --grep="Task-Status: completed" --pretty=format:"%h %s %ad" --date=short

# Export task report
git log --grep="Task-Status: completed" --pretty=format:"%h|%s|%ad" --date=short > tasks.csv
```

### Git Hook Installation

Install the commit-msg hook to validate task commits:

```bash
# Copy hook to your git directory
cp node_modules/@papaoloba/nightly-code-orchestrator/hooks/commit-msg .git/hooks/
chmod +x .git/hooks/commit-msg
```

The hook validates:
- Proper commit format for task completions
- Required metadata in commit footer
- Task ID format and consistency
- Conventional commit compliance

## Security and Safety

### Sandboxing

Enable sandbox mode for additional security:

```yaml
security:
  sandbox_mode: true
  allowed_commands:
    - "npm"
    - "node"
    - "git"
  blocked_patterns:
    - "rm -rf"
    - "sudo"
    - "curl"
  max_file_size: 10485760  # 10MB
```

### File Access Control

Restrict file modifications:

```yaml
tasks:
  - id: "safe-task"
    files_to_modify:
      - "src/components/"  # Only allow changes in specific directories
      - "test/"
```

### Command Validation

All commands are validated before execution:

- Commands must be in the allowed list (if specified)
- Blocked patterns are rejected
- File size limits are enforced
- Network access can be restricted

## Performance and Monitoring

### Resource Monitoring

The orchestrator continuously monitors:

- **CPU usage** - Warns if consistently above 90%
- **Memory usage** - Alerts on excessive memory consumption
- **Disk space** - Ensures adequate space for operations
- **Network connectivity** - Validates access to required services

### Checkpointing

Automatic checkpoints every 5 minutes (configurable) include:

- Current task state
- Completed/failed tasks
- Resource usage history
- Git branch information
- Time elapsed

### Performance Metrics

Each session tracks:

- Tasks completed per hour
- Average task duration
- Time utilization percentage
- Error rate
- Resource efficiency

## Troubleshooting

### Common Issues

#### "Claude Code CLI not found"

```bash
# Install Claude Code
npm install -g claude-code

# Verify installation
claude-code --version
```

#### "Configuration validation failed"

```bash
# Check configuration syntax
# If installed globally
nightly-code validate

# If installed locally
npx nightly-code validate

# Fix common issues automatically
# If installed globally
nightly-code validate --fix

# If installed locally
npx nightly-code validate --fix
```

#### "Git repository not found"

```bash
# Initialize git repository
git init
git add .
git commit -m "Initial commit"
```

#### "Task dependencies cannot be resolved"

Check for circular dependencies:

```yaml
tasks:
  - id: "task-a"
    dependencies: ["task-b"]  # task-a depends on task-b
  - id: "task-b" 
    dependencies: ["task-a"]  # task-b depends on task-a (circular!)
```

### Dependency-Aware Branching

Nightly Code now supports intelligent Git branching that respects task dependencies. When a task depends on another task, it will automatically branch from the dependency's branch instead of main, ensuring all dependent code is available.

#### How It Works

1. **Independent Tasks**: Branch from main as usual
2. **Dependent Tasks**: Branch from the last dependency's branch
3. **Missing Dependencies**: Fall back to main with a warning

Example workflow:
```
main
 └─ task/setup-db (Task A)
     └─ task/create-api (Task B depends on A)
         └─ task/add-tests (Task C depends on B)
```

#### Configuration

Control dependency branching behavior in `nightly-code.yaml`:

```yaml
git:
  # Enable branching from dependency branches (default: true)
  dependency_aware_branching: true
  
  # Auto-merge tasks that have dependents (default: false)
  merge_dependency_chains: false
  
  # Fail if dependency branches are missing (default: false)
  strict_dependency_checking: false
```

#### Task Dependencies Example

```yaml
tasks:
  - id: "setup-database"
    type: "feature"
    title: "Set up database schema"
    requirements: "Create initial database tables and migrations"
    dependencies: []  # No dependencies - branches from main

  - id: "create-api"
    type: "feature"
    title: "Create REST API"
    requirements: "Implement CRUD endpoints for database entities"
    dependencies: ["setup-database"]  # Branches from setup-database branch

  - id: "add-authentication"
    type: "feature"
    title: "Add authentication"
    requirements: "Implement JWT authentication for API"
    dependencies: ["create-api"]  # Branches from create-api branch

  - id: "add-tests"
    type: "test"
    title: "Add integration tests"
    requirements: "Test API endpoints with authentication"
    dependencies: ["create-api", "add-authentication"]  # Branches from add-authentication (last dependency)
```

### Debug Mode

Enable detailed logging:

```bash
# Set log level
export NIGHTLY_CODE_LOG_LEVEL=debug

# Run with verbose output
# If installed globally
nightly-code run --verbose

# If installed locally
npx nightly-code run --verbose
```

### Log Files

Logs are stored in `.nightly-code/logs/`:

- `nightly-code.log` - General application logs
- `sessions.log` - Detailed session logs
- `scheduler.log` - Scheduling and cron logs

## Best Practices

### Task Design

1. **Be Specific**: Write detailed requirements and acceptance criteria
2. **Keep Tasks Focused**: Aim for 1-3 hours per task
3. **Define Dependencies**: Clearly specify task relationships
4. **Include Validation**: Add custom validation scripts for complex tasks
5. **Test Thoroughly**: Ensure acceptance criteria are testable

### Configuration Management

1. **Version Control**: Commit configuration files to git
2. **Environment Specific**: Use different configs for dev/staging/prod
3. **Secret Management**: Use environment variables for sensitive data
4. **Regular Validation**: Run `nightly-code validate` after changes

### Security Guidelines

1. **Principle of Least Privilege**: Only allow necessary commands
2. **Regular Updates**: Keep dependencies and tools updated
3. **Code Review**: Review generated code before merging
4. **Backup Strategy**: Maintain regular backups of important data
