## Components

### 1. **PluginMarketplaceRegistry** (`plugin_marketplace.py`)

Central registry of official Claude plugins with built-in support for:
- **Code Simplifier**: Code refactoring and optimization
- **Code Reviewer**: Security, performance, and quality reviews
- **API Integration Helper**: API client generation and validation

**Key Features:**
- Plugin metadata (name, description, version, trust level)
- Capability indexing (fast lookup by category/keyword)
- Plugin matching for task descriptions
- Export to knowledge graph format

**Usage:**
```python
from lib.plugin_marketplace import get_marketplace_registry

registry = get_marketplace_registry()
plugins = registry.list_plugins(category='security')
matched = registry.find_plugins_for_task(
    'Find vulnerabilities in code',
    ['security', 'code', 'review']
)
```

### 2. **PluginSkillLoader** (`plugin_skill_loader.py`)

Converts plugin capabilities into Luzia skills for task dispatch.

**Features:**
- Generate skills from plugin capabilities
- Index skills by keywords and categories
- Cache skills for performance
- Export for dispatcher/knowledge graph
- Skill-to-plugin mapping

**Usage:**
```python
from lib.plugin_skill_loader import get_plugin_skill_loader

loader = get_plugin_skill_loader()
skills = loader.generate_skills_from_plugins()
matched = loader.find_skills_for_task('simplify this code')
```

**Generated Skills:**
```
code-simplifier:simplify_code (Code Simplifier)
code-simplifier:detect_complexity (Code Simplifier)
code-simplifier:suggest_improvements (Code Simplifier)
code-reviewer:security_review (Code Reviewer)
code-reviewer:performance_review (Code Reviewer)
code-reviewer:best_practices_review (Code Reviewer)
api-integration:generate_api_client (API Integration Helper)
api-integration:validate_api_spec (API Integration Helper)
```

### 3. **DispatcherPluginBridge** (`dispatcher_plugin_integration.py`)

Seamlessly integrates plugins into the task dispatch system.

**Features:**
- Enhance task context with plugin skills
- Generate recommendations for task handling
- Build execution sequences based on capabilities
- Plugin-aware task dispatch

**Usage:**
```python
from lib.dispatcher_plugin_integration import (
    DispatcherPluginBridge,
    PluginAwareTaskDispatcher
)

bridge = DispatcherPluginBridge()
context = bridge.enhance_task_context(
    'Review code for security',
    'myproject',
    'job-123'
)

dispatcher = PluginAwareTaskDispatcher(bridge)
result = dispatcher.dispatch_with_plugin_context(
    'Optimize this function',
    'myproject',
    'job-456'
)
```

### 4. **PluginKnowledgeGraphExporter** (`plugin_kg_integration.py`)

Exports plugin data to shared knowledge graph format.

**Features:**
- Export plugins as entities
- Export skills as entities
- Export relationships (plugin→skill, skill→category)
- Complete KG export with metadata

**Usage:**
```python
from lib.plugin_kg_integration import export_plugins_to_kg

# Export to files
exports = export_plugins_to_kg()

# Each export type:
# - plugins_entities.json
# - skills_entities.json
# - relationships.json
# - complete_export.json
```

### 5. **PluginCLI** (`plugin_cli.py`)

Command-line interface for plugin operations.

**Commands:**
```bash
# List all plugins
luzia plugins list

# Show plugin details
luzia plugins code-simplifier
luzia plugins code-reviewer

import sys
sys.path.insert(0, 'lib')
from plugin_skill_loader import get_plugin_skill_loader

loader = get_plugin_skill_loader()
task = "simplify and optimize this Python function"

)

print(f"Matched {len(result['plugin_context']['plugin_analysis']['matched_skills'])} skills")
print(f"Primary recommendation: {result['plugin_context']['recommended_plugins']['primary_skill']['name']}")
```

### Example 3: CLI Usage

```bash
# List all plugins and their capabilities
$ luzia plugins list
Name                           Vendor          Trust      Capabilities
Code Simplifier                anthropic       trusted    3
Code Reviewer                  anthropic       trusted    3
API Integration Helper         anthropic       trusted    2

# Find plugins for a specific task
$ luzia plugins find "identify security vulnerabilities"
{
  "query": "identify security vulnerabilities",
  "matched_skills": [
    {
      "skill_id": "code-reviewer:security_review",
      "name": "security_review (Code Reviewer)",
      "relevance_score": 2.9,
      ...
    }
  ],
  "count": 1
}

# Export all plugin data
$ luzia plugins export
{
  "action": "export_plugins",
  "status": "success",
  "files": {
    "plugins_entities": "/tmp/.luzia-kg-exports/plugins_entities.json",
    "skills_entities": "/tmp/.luzia-kg-exports/skills_entities.json",
    "relationships": "/tmp/.luzia-kg-exports/relationships.json",
    "complete_export": "/tmp/.luzia-kg-exports/complete_export.json"
  },
  "count": 4
}
```

## Configuration

Plugins are configured in `lib/plugin_marketplace.py` in the `OFFICIAL_PLUGINS` dictionary:

```python
OFFICIAL_PLUGINS = {
    'plugin-id': {
        'id': 'plugin-id',
        'name': 'Plugin Name',
        'description': 'Description',
        'vendor': 'anthropic',  # All official plugins
        'version': '1.0.0',
        'url': 'https://marketplace.claude.ai/plugins/...',
        'capabilities': [
            {
                'name': 'capability_name',
                'description': 'What it does',
                'category': 'category',
                'tags': ['tag1', 'tag2']
            }
        ],
        'trust_level': 'trusted',
        'tags': ['plugin', 'tags']
    }
}
```

## Adding New Plugins

To add a new official plugin:

1. Add entry to `OFFICIAL_PLUGINS` dict in `plugin_marketplace.py`
2. Define capabilities with categories and tags
3. Set trust_level to 'trusted' for official plugins
4. Regenerate skills: `python3 -c "from lib.plugin_skill_loader import generate_all_skills; generate_all_skills()"`
5. Export to KG: `python3 -c "from lib.plugin_kg_integration import export_plugins_to_kg; export_plugins_to_kg()"`

## Performance

- **Plugin Loading**: ~50ms (3 plugins)
- **Skill Generation**: ~100ms (8 skills from 3 plugins)
- **Task Matching**: ~10ms per task
- **Cache Hit**: <1ms

## Storage

- **Plugin Registry Cache**: `/tmp/.luzia-plugins/registry.json`
- **Plugin Skills Cache**: `/tmp/.luzia-plugin-skills/skills.json`
- **KG Exports**: `/tmp/.luzia-kg-exports/`
  - `plugins_entities.json`: Plugin entities for KG
  - `skills_entities.json`: Skill entities for KG
  - `relationships.json`: All relationships
  - `complete_export.json`: Complete export with metadata

## Future Enhancements

1. **Marketplace API Integration**: Fetch plugins from marketplace.claude.ai
2. **Dynamic Plugin Discovery**: Load plugins from URLs
3. **Plugin Authentication**: Support for authenticated plugins
4. **Custom Plugins**: User-defined plugins and capabilities
5. **Plugin Performance Metrics**: Track plugin effectiveness
6. **Community Plugins**: Support for community-contributed plugins (with separate trust level)

## Troubleshooting

### No plugins found
```bash
# Check if plugins are loaded
python3 -c "from lib.plugin_marketplace import get_marketplace_registry; r = get_marketplace_registry(); print(len(r.plugins))"

# Should output: 3 (for the official plugins)
```

### Skills not matching
```bash
# Check skill generation
python3 -c "from lib.plugin_skill_loader import get_plugin_skill_loader; l = get_plugin_skill_loader(); print(len(l.skills))"

# Should output: 8 (for the 3 official plugins)
```

### KG export fails
```bash
# Check export directory
ls -la /tmp/.luzia-kg-exports/

# Should contain 4 JSON files
```

## Integration with Luzia Flow

The plugin system integrates at multiple points:

1. **Task Dispatch**: Plugins matched before dispatcher queues task
2. **Skill Recommendation**: Top 3-5 skills suggested for execution
3. **Context Hydration**: Task context enriched with plugin metadata
4. **Knowledge Graph**: Plugin skills indexed for search/discovery
