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:

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:

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:

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:

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:

# List all plugins
luzia plugins list

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

# List all skills
luzia plugins skills

# Find plugins for a task
luzia plugins find "review code for security"

# Export plugin data

Usage Examples

Example 1: Find Plugins for Task

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"
matched = loader.find_skills_for_task(task, min_relevance=0.3)

for skill in matched:
    print(f"{skill['name']}: {skill['description']}")

Example 2: Dispatch Task with Plugin Context

from dispatcher_plugin_integration import PluginAwareTaskDispatcher

dispatcher = PluginAwareTaskDispatcher()
result = dispatcher.dispatch_with_plugin_context(
    task_description='Review code for security issues',
    project='my-project',
    job_id='job-789'
)

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

# 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:

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

# 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

# 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

# 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
