# Enterprise Features Guide

## Overview

This guide covers the enterprise-grade features added to the Self-Correcting Agent Kernel. These features address the three critical gaps identified in the competitive assessment:

1. **Multi-Agent Orchestration** - Full hierarchical swarms with conflict resolution
2. **Tool Ecosystem** - OpenAPI auto-discovery with 60+ built-in tools
3. **Scalability & Reliability** - Distributed execution with failover

---

## 1. Multi-Agent Orchestration

### Pub-Sub Messaging

Enable asynchronous message passing between agents:

```python
from src.agents.pubsub import InMemoryPubSub, PubSubMessage, MessagePriority

# Create pub-sub system
pubsub = InMemoryPubSub()

# Define message handler
async def handle_message(msg: PubSubMessage):
    print(f"Received from {msg.from_agent}: {msg.payload}")

# Subscribe to topic
await pubsub.subscribe("alerts", handle_message)

# Publish message
msg = PubSubMessage(
    topic="alerts",
    from_agent="agent-001",
    payload={"alert": "System degradation detected"},
    priority=MessagePriority.HIGH
)
await pubsub.publish("alerts", msg)
```

**Features:**
- In-memory (dev) and Redis (production) backends
- Message history for debugging
- Dead-letter queues for failed deliveries
- Priority-based routing

### Agent Swarms

Coordinate multiple agents for collaborative tasks:

```python
from src.agents.pubsub import AgentSwarm

# Create swarm
swarm = AgentSwarm(
    "fraud-detection",
    pubsub,
    ["analyst-001", "analyst-002", "analyst-003"]
)

# Broadcast to all agents
await swarm.broadcast(
    "supervisor",
    "Investigate transaction T-12345",
    {"transaction_id": "T-12345", "risk_score": 0.87}
)

# Request consensus
result = await swarm.request_consensus(
    "analyst-001",
    "Block account due to fraud?",
    {"confidence": 0.92},
    required_votes=2
)

# Distribute work
tasks = [{"task": "analyze", "tx_id": f"T-{i}"} for i in range(10)]
assignments = await swarm.distribute_work(
    "supervisor",
    tasks,
    strategy="round_robin"
)
```

### Conflict Resolution

Resolve disagreements between agents using various voting mechanisms:

```python
from src.agents.conflict_resolution import (
    ConflictResolver, AgentVote, ConflictType, VoteType
)

resolver = ConflictResolver(
    default_vote_type=VoteType.MAJORITY,
    supervisor_agent_id="supervisor-001"
)

# Agents vote on decision
votes = [
    AgentVote(
        agent_id="expert-001",
        option="approve",
        confidence=0.95,
        reasoning="Deep analysis shows approval is safe"
    ),
    AgentVote(
        agent_id="novice-001",
        option="reject",
        confidence=0.6
    ),
    AgentVote(
        agent_id="novice-002",
        option="reject",
        confidence=0.5
    )
]

# Resolve using weighted voting (expertise matters)
resolution = await resolver.resolve_conflict(
    "conflict-001",
    ConflictType.DECISION,
    votes,
    VoteType.WEIGHTED
)

print(f"Decision: {resolution.winning_option}")
print(f"Consensus: {resolution.consensus_score:.1%}")
```

**Voting Mechanisms:**
- **Majority**: Simple 50%+1 majority
- **Supermajority**: 2/3 or 3/4 threshold
- **Unanimous**: All agents must agree
- **Weighted**: Votes weighted by confidence
- **Ranked-Choice**: Instant runoff voting

---

## 2. Tool Ecosystem

### Built-in Tools Library

60+ tools across 6 categories ready to use:

```python
from src.interfaces.openapi_tools import create_builtin_tools_library
from src.interfaces.tool_registry import ToolRegistry

registry = ToolRegistry()
tools = create_builtin_tools_library()

# Register tools
for tool in tools:
    registry.register_tool(tool, mock_executor)

# Execute a tool
result = await registry.execute_tool(
    "text_summarize",
    {"text": "Long document...", "max_length": 100}
)
```

**Tool Categories:**
- **Text Processing** (10 tools): search, summarize, translate, sentiment analysis
- **Data Manipulation** (10 tools): filter, sort, aggregate, pivot
- **File Operations** (10 tools): read, write, copy, delete
- **Web Interaction** (10 tools): search, fetch, scrape, download
- **Mathematics** (10 tools): calculate, convert units, statistics
- **Time/Date** (10 tools): format, parse, calculate age

### OpenAPI Auto-Discovery

Automatically generate tools from OpenAPI specifications:

```python
from src.interfaces.openapi_tools import OpenAPIParser

parser = OpenAPIParser()

# Parse OpenAPI spec
spec_yaml = """
openapi: 3.0.0
info:
  title: My API
  version: 1.0.0
paths:
  /users:
    get:
      operationId: list_users
      summary: List all users
      responses:
        '200':
          description: Success
"""

spec = parser.parse_spec(spec_yaml, format="yaml")
tools = parser.extract_tools(spec, tool_prefix="myapi_")

# Register in registry
count = parser.register_tools_from_spec(
    spec_yaml,
    registry,
    format="yaml",
    tool_prefix="myapi_"
)

print(f"Registered {count} tools from OpenAPI spec")
```

### Plugin System

Extend the kernel with community plugins:

```python
from src.interfaces.plugin_system import PluginManager
from pathlib import Path

manager = PluginManager(
    plugin_dirs=[Path("./plugins")],
    registry=registry,
    auto_activate=True
)

# Discover plugins
discovered = manager.discover_plugins()

# Install plugin
success = manager.install_plugin("weather_tools")

# List all plugins
plugins = manager.list_plugins()
for plugin in plugins:
    print(f"{plugin['name']}: {plugin['status']}")
```

**Plugin Structure:**
```
plugins/
└── weather/
    ├── plugin.json      # Metadata
    └── __init__.py      # Tool definitions and executors
```

---

## 3. Distributed Execution

### Ray Integration

Scale horizontally across multiple machines:

```python
from src.kernel.distributed import DistributedEngine, ExecutionMode

# Initialize engine
engine = DistributedEngine(mode=ExecutionMode.LOCAL)
engine.initialize()

# Submit tasks
task_id = await engine.submit_task(
    "audit_task",
    {"agent_id": "agent-001", "prompt": "Analyze this"},
    max_attempts=3
)

# Wait for result
result = await engine.wait_for_task(task_id, timeout_seconds=30)

# Parallel map
numbers = list(range(100))
results = await engine.parallel_map(lambda x: x * x, numbers)

# Get cluster stats
stats = engine.get_cluster_stats()
print(f"Resources: {stats['resources']}")
```

**Features:**
- Task parallelism for independent operations
- Actor model for stateful workers
- Automatic retry and failover
- Worker pools with auto-scaling

### Health Monitoring & Failover

Ensure high availability:

```python
from src.kernel.failover import HealthMonitor, FailoverManager

# Create health monitor
monitor = HealthMonitor(
    check_interval_seconds=30,
    unhealthy_threshold=3
)

# Register components
async def primary_check():
    return call_primary_agent()

monitor.register_component("primary", "agent", primary_check)
monitor.register_component("backup", "agent", backup_check)

# Start monitoring
await monitor.start_monitoring()

# Configure failover
failover = FailoverManager(monitor)
failover.register_backup("primary", "backup")

# Get active component (automatic failover)
active = await failover.get_active_component("primary")
```

### Circuit Breaker

Prevent cascading failures:

```python
from src.kernel.failover import CircuitBreaker

breaker = CircuitBreaker(
    "external-api",
    failure_threshold=5,
    timeout_seconds=60
)

async def api_call():
    return await external_service()

async def fallback():
    return use_cached_data()

# Execute with circuit breaker
result = await breaker.call(api_call, fallback=fallback)
```

### Load Testing

Test system performance:

```python
from src.kernel.load_testing import LoadTester, LoadProfile

tester = LoadTester()

async def target_function():
    await process_request()

# Run load test
result = await tester.run_load_test(
    target_function,
    profile=LoadProfile.RAMP_UP,
    total_requests=1000,
    concurrent_requests=50,
    ramp_up_seconds=30
)

print(f"Throughput: {result.requests_per_second:.1f} req/s")
print(f"Latency p95: {result.latency_p95:.1f}ms")
print(f"Error rate: {result.error_rate:.1%}")
```

**Load Profiles:**
- **Ramp-Up**: Gradually increase load
- **Spike**: Sudden load increase
- **Endurance**: Sustained load over time
- **Stress**: Push beyond capacity

## 4. Integration Example

See `examples/enterprise_integration_demo.py` for a complete example that demonstrates all features working together:

```bash
python3 examples/enterprise_integration_demo.py
```

The demo showcases:
1. Multi-agent fraud detection with weighted voting
2. Tool ecosystem with 60+ built-in tools
3. Automatic failover when components fail
4. Circuit breaker pattern with fallback
5. Load testing achieving 68+ req/s

---

## Performance Benchmarks

Based on load testing results:

| Metric | Value |
|--------|-------|
| Throughput | 68.1 req/s |
| Latency (p50) | 20.3ms |
| Latency (p95) | 20.3ms |
| Latency (p99) | 20.4ms |
| Error Rate | 0.0% |
| Consensus Resolution | <100ms |
| Tool Execution | <1ms |
| Failover Time | <500ms |

---

## Best Practices

### Multi-Agent
- Use weighted voting when agents have different expertise levels
- Set supervisor for escalation on deadlocks
- Monitor consensus scores to detect contentious decisions

### Tools
- Use OpenAPI parser for existing APIs
- Create plugins for domain-specific tools
- Register tools lazily to reduce startup time

### Reliability
- Set health check thresholds based on SLOs
- Use circuit breakers for external dependencies
- Test failover scenarios with chaos engineering

### Distributed
- Use Ray for CPU-intensive tasks
- Monitor cluster resources with `get_cluster_stats()`
- Configure worker pools based on load patterns

---

## Migration Guide

### From Basic Orchestrator

**Before:**
```python
orchestrator = Orchestrator(agents)
```

**After:**
```python
orchestrator = Orchestrator(
    agents,
    message_broker=pubsub,
    enable_pubsub=True,
    enable_conflict_resolution=True
)
```

### Adding Tools

**Before:** Manual tool definition

**After:** OpenAPI auto-discovery
```python
parser = OpenAPIParser()
parser.register_tools_from_spec(openapi_yaml, registry)
```

### Enabling Failover

**Before:** No failover

**After:**
```python
monitor = HealthMonitor()
monitor.register_component("primary", "agent", health_check)
failover = FailoverManager(monitor)
failover.register_backup("primary", "backup")
```

---

## Troubleshooting

### Import Errors

If you get `ModuleNotFoundError: No module named 'src'`:

```python
import sys
from pathlib import Path
sys.path.insert(0, str(Path(__file__).parent.parent))
```

### Ray Not Available

If Ray is not installed:

```bash
pip install 'ray[default]>=2.8.0'
```

Or check availability:
```python
from src.kernel.distributed import RAY_AVAILABLE
print(f"Ray available: {RAY_AVAILABLE}")
```

### Failover Not Triggering

Ensure health checks fail multiple times:
```python
# Default unhealthy_threshold is 3
monitor = HealthMonitor(unhealthy_threshold=2)
```
