## Phase 3: New Components

### 1. Knowledge-Context Synchronization

**Location**: `agentuniverse/agent/context/sync/knowledge_context_synchronizer.py`

**Purpose**: Bidirectional synchronization between Knowledge and Context systems with conflict resolution.

#### Key Features

- **4 Conflict Resolution Strategies**:
  - `NEWEST_WINS`: Most recent knowledge takes precedence
  - `CRITICAL_PRESERVED`: CRITICAL priority segments always kept
  - `MERGE`: Combine both versions
  - `VERSION_BOTH`: Keep both as versioned segments

- **Version Tracking**: SHA256 hash-based change detection
- **Selective Invalidation**: Mark outdated segments without deletion
- **Efficient Updates**: Only sync when content changes

#### Basic Usage

```python
from agentuniverse.agent.context.sync.knowledge_context_synchronizer import (
    KnowledgeContextSynchronizer,
    ConflictResolutionStrategy
)
from agentuniverse.agent.context.context_manager_manager import ContextManagerManager

# Get context manager instance
context_manager = ContextManagerManager().get_instance_obj("default_context_manager")

# Create synchronizer
synchronizer = KnowledgeContextSynchronizer(
    context_manager=context_manager,
    conflict_strategy=ConflictResolutionStrategy.NEWEST_WINS,
    enable_versioning=True
)

# Sync knowledge to context
result = synchronizer.sync_knowledge_to_context(
    knowledge_id="user_manual_v2",
    documents=["Updated user manual content...", "New API documentation..."],
    session_id="session_123",
    source="knowledge_base",
    priority=ContextPriority.HIGH
)

print(f"Added {result.segments_added} segments")
print(f"Invalidated {result.segments_invalidated} old segments")
```

#### Update Existing Knowledge

```python
# Update when knowledge changes
result = synchronizer.update_knowledge_context(
    knowledge_id="user_manual_v2",
    session_id="session_123",
    new_documents=["Updated content with corrections..."],
    conflict_strategy=ConflictResolutionStrategy.CRITICAL_PRESERVED
)

print(f"Resolved {result.conflicts_resolved} conflicts")
print(f"Updated {result.segments_updated} segments")
```

#### Version Tracking

```python
# Get version information
version = synchronizer.get_knowledge_version("user_manual_v2")
if version:
    print(f"Version ID: {version.version_id}")
    print(f"Source: {version.source}")
    print(f"Hash: {version.hash}")
    print(f"Timestamp: {version.timestamp}")

# List all versions
all_versions = synchronizer.list_knowledge_versions()
for knowledge_id, version in all_versions.items():
    print(f"{knowledge_id}: {version.version_id}")
```

### 2. Benchmarking Framework

**Location**: `agentuniverse/agent/context/benchmark/benchmark_suite.py`

**Purpose**: Comprehensive evaluation against industry standards (Cursor, Claude).

#### Benchmark Targets

| Metric | Target | Description |
|--------|--------|-------------|
| Multi-turn coherence | >0.85 | Context preservation across turns |
| Compression ratio | 60-80% | Token reduction efficiency |
| Information loss | <10% | Semantic preservation |
| Retrieval precision | >0.90 | Search accuracy |
| Retrieval latency | <100ms | Search speed |
| Memory usage | <500MB | For 10K turns |

#### Basic Usage

```python
from agentuniverse.agent.context.benchmark.benchmark_suite import (
    ContextBenchmarkSuite
)
from agentuniverse.agent.context.context_manager_manager import ContextManagerManager

# Get context manager
context_manager = ContextManagerManager().get_instance_obj("default_context_manager")

# Create benchmark suite
suite = ContextBenchmarkSuite(context_manager)

# Run full benchmark (100 turns by default)
result = suite.run_full_suite(num_turns=100)

# Check results
print(f"Overall Score: {result.metrics.get_score():.1f}/100")
print(f"Passes Targets: {result.metrics.passes_targets()}")
print(f"Multi-turn Coherence: {result.metrics.multi_turn_coherence:.3f}")
print(f"Compression Ratio: {result.metrics.compression_ratio:.1%}")
print(f"Information Loss: {result.metrics.information_loss:.1%}")
print(f"Retrieval Precision: {result.metrics.retrieval_precision:.3f}")
print(f"Average Latency: {result.metrics.average_latency_ms:.1f}ms")
print(f"Memory Usage: {result.metrics.memory_usage_mb:.1f}MB")
```

#### Detailed Metrics

```python
# Access detailed metrics
metrics = result.metrics

# Coherence metrics
print(f"Multi-turn coherence: {metrics.multi_turn_coherence:.3f}")
print(f"Context consistency: {metrics.context_consistency:.3f}")

# Compression metrics
print(f"Compression ratio: {metrics.compression_ratio:.1%}")
print(f"Information loss: {metrics.information_loss:.1%}")
print(f"Context preservation: {metrics.context_preservation:.1%}")

# Retrieval metrics
print(f"Precision: {metrics.retrieval_precision:.3f}")
print(f"Recall: {metrics.retrieval_recall:.3f}")
print(f"F1 Score: {metrics.retrieval_f1:.3f}")

# Performance metrics
print(f"Average latency: {metrics.average_latency_ms:.1f}ms")
print(f"P95 latency: {metrics.p95_latency_ms:.1f}ms")
print(f"P99 latency: {metrics.p99_latency_ms:.1f}ms")
print(f"Throughput: {metrics.throughput_ops_per_sec:.1f} ops/sec")

# Resource metrics
print(f"Memory usage: {metrics.memory_usage_mb:.1f}MB")
print(f"Tokens per turn (avg): {metrics.tokens_per_turn_avg:.1f}")
```

## Phase 4: Agent Integration Patterns

### Pattern 1: Context-Aware Agent (Basic)

**Use Case**: Single agent with context management

**Configuration** (`agent_context_aware.yaml`):

```yaml
name: 'context_aware_agent'
description: 'Agent with advanced context management'

profile:
  llm_model:
    name: 'gpt-4'
    max_tokens: 2000

  # Enable context manager
  context_manager_name: 'default_context_manager'
  task_type: 'dialogue'  # code_generation, data_analysis, dialogue

  system_prompt: |
    You are an intelligent assistant with advanced context awareness.
    You can maintain coherent conversations across multiple turns.

memory:
  name: 'demo_memory'

action:
  knowledge:
    - 'demo_knowledge'

plan:
  planner:
    name: 'react_planner'
```

**Implementation**:

```python
from agentuniverse.agent.agent import Agent
from agentuniverse.agent.agent_manager import AgentManager
from agentuniverse.agent.context.context_manager_manager import ContextManagerManager

class ContextAwareAgent(Agent):
    """Agent with integrated context management."""

    def __init__(self):
        super().__init__()
        self._context_manager = None

    def initialize_by_component_configer(self, component_configer):
        """Initialize with context manager."""
        super().initialize_by_component_configer(component_configer)

        # Get context manager name from profile
        context_manager_name = self.agent_model.profile.get('context_manager_name')
        if context_manager_name:
            self._context_manager = ContextManagerManager().get_instance_obj(
                context_manager_name
            )

        return self

    def pre_parse_input(self, input_object):
        """Enhanced input parsing with context extraction."""
        agent_input = super().pre_parse_input(input_object)

        # If context manager is enabled
        if self._context_manager:
            session_id = input_object.get_data('session_id')
            if session_id:
                # Create or get context window
                task_type = self.agent_model.profile.get('task_type', 'dialogue')
                window = self._context_manager.create_context_window(
                    session_id=session_id,
                    agent_id=self.agent_model.info.get('name'),
                    task_type=task_type
                )

                # Add user input to context
                user_input = input_object.get_data('input')
                if user_input:
                    self._context_manager.add_context(
                        session_id,
                        user_input,
                        ContextType.CONVERSATION,
                        ContextPriority.HIGH,
                        metadata={'role': 'user'}
                    )

                # Add system prompt to context (CRITICAL priority)
                system_prompt = self.agent_model.profile.get('system_prompt')
                if system_prompt:
                    self._context_manager.add_context(
                        session_id,
                        system_prompt,
                        ContextType.SYSTEM,
                        ContextPriority.CRITICAL
                    )

                # Get context for building agent input
                agent_input['context_window'] = window

        return agent_input

    def parse_result(self, agent_result):
        """Enhanced result parsing with context storage."""
        result = super().parse_result(agent_result)

        # Store agent output in context
        if self._context_manager:
            session_id = agent_result.get('session_id')
            output = result.get('output')
            if session_id and output:
                self._context_manager.add_context(
                    session_id,
                    output,
                    ContextType.CONVERSATION,
                    ContextPriority.HIGH,
                    metadata={'role': 'assistant'}
                )

        return result
```

### Pattern 2: Knowledge-Integrated Agent

**Use Case**: Agent with automatic knowledge-context synchronization

**Implementation**:

```python
from agentuniverse.agent.context.sync.knowledge_context_synchronizer import (
    KnowledgeContextSynchronizer
)

class KnowledgeIntegratedAgent(ContextAwareAgent):
    """Agent with knowledge-context synchronization."""

    def __init__(self):
        super().__init__()
        self._synchronizer = None

    def initialize_by_component_configer(self, component_configer):
        """Initialize with synchronizer."""
        super().initialize_by_component_configer(component_configer)

        # Create synchronizer if context manager exists
        if self._context_manager:
            self._synchronizer = KnowledgeContextSynchronizer(
                context_manager=self._context_manager,
                enable_versioning=True
            )

        return self

    def execute(self, input_object, agent_input):
        """Execute with knowledge synchronization."""
        session_id = input_object.get_data('session_id')

        # Sync knowledge before execution
        if self._synchronizer and session_id:
            knowledge_configs = self.agent_model.action.get('knowledge', [])
            for knowledge_config in knowledge_configs:
                knowledge_name = knowledge_config.get('name') if isinstance(knowledge_config, dict) else knowledge_config

                # Get knowledge documents (simplified)
                from agentuniverse.agent.action.knowledge.knowledge_manager import KnowledgeManager
                knowledge = KnowledgeManager().get_instance_obj(knowledge_name)
                if knowledge:
                    # Query relevant documents
                    query = input_object.get_data('input', '')
                    documents = knowledge.query_knowledge(query, top_k=5)

                    # Sync to context
                    if documents:
                        self._synchronizer.sync_knowledge_to_context(
                            knowledge_id=knowledge_name,
                            documents=[doc.text for doc in documents],
                            session_id=session_id,
                            priority=ContextPriority.HIGH
                        )

        # Execute normally
        return super().execute(input_object, agent_input)
```

### Pattern 3: Cross-Agent Context Sharing

**Use Case**: Multiple agents sharing context in a multi-agent system

**Implementation**:

```python
class AgentContextCoordinator:
    """Coordinates context sharing across multiple agents."""

    def __init__(self, context_manager_name: str = "default_context_manager"):
        self.context_manager = ContextManagerManager().get_instance_obj(
            context_manager_name
        )
        self._shared_sessions = {}  # agent_group_id -> session_id

    def create_shared_session(self, agent_group_id: str) -> str:
        """Create a shared context session for a group of agents."""
        session_id = f"shared_{agent_group_id}_{datetime.now().timestamp()}"
        window = self.context_manager.create_context_window(
            session_id=session_id,
            task_type="dialogue"
        )
        self._shared_sessions[agent_group_id] = session_id
        return session_id

    def share_context(
        self,
        agent_group_id: str,
        content: str,
        source_agent: str,
        context_type: ContextType = ContextType.CONVERSATION,
        priority: ContextPriority = ContextPriority.MEDIUM
    ):
        """Share context from one agent to the group."""
        session_id = self._shared_sessions.get(agent_group_id)
        if not session_id:
            session_id = self.create_shared_session(agent_group_id)

        self.context_manager.add_context(
            session_id,
            content,
            context_type,
            priority,
            metadata={
                'source_agent': source_agent,
                'shared': True,
                'timestamp': datetime.now().isoformat()
            }
        )

    def get_shared_context(
        self,
        agent_group_id: str,
        context_type: Optional[ContextType] = None
    ) -> List[ContextSegment]:
        """Get shared context for the agent group."""
        session_id = self._shared_sessions.get(agent_group_id)
        if not session_id:
            return []

        return self.context_manager.get_context(
            session_id,
            context_type=context_type
        )

# Usage
coordinator = AgentContextCoordinator()

# Create shared session for multiple agents
session_id = coordinator.create_shared_session("research_team")

# Agent 1 shares findings
coordinator.share_context(
    agent_group_id="research_team",
    content="Found relevant research paper on topic X",
    source_agent="research_agent",
    priority=ContextPriority.HIGH
)

# Agent 2 shares analysis
coordinator.share_context(
    agent_group_id="research_team",
    content="Analysis shows correlation with previous findings",
    source_agent="analysis_agent",
    priority=ContextPriority.HIGH
)

# Agent 3 retrieves all shared context
shared_context = coordinator.get_shared_context("research_team")
for segment in shared_context:
    print(f"From {segment.metadata.custom['source_agent']}: {segment.content}")
```

## Testing Phase 3-4 Features

### Test 1: Knowledge Synchronization

```python
def test_knowledge_sync():
    """Test knowledge-context synchronization."""
    from agentuniverse.agent.context.sync.knowledge_context_synchronizer import (
        KnowledgeContextSynchronizer,
        ConflictResolutionStrategy
    )

    context_manager = ContextManagerManager().get_instance_obj("default_context_manager")
    synchronizer = KnowledgeContextSynchronizer(context_manager)

    # Test 1: Initial sync
    result = synchronizer.sync_knowledge_to_context(
        knowledge_id="test_doc",
        documents=["Content version 1"],
        session_id="test_session",
        priority=ContextPriority.HIGH
    )
    assert result.segments_added == 1
    assert result.segments_invalidated == 0

    # Test 2: Update with no changes
    result = synchronizer.sync_knowledge_to_context(
        knowledge_id="test_doc",
        documents=["Content version 1"],  # Same content
        session_id="test_session"

        invalidate_old=True
    )
    assert result.segments_added == 1
    assert result.segments_invalidated == 1

    # Test 4: Version tracking
    version = synchronizer.get_knowledge_version("test_doc")
    assert version is not None
    assert version.version_id.startswith("test_doc_")

    print("✅ All knowledge sync tests passed")

test_knowledge_sync()
```

### Test 2: Benchmarking

```python
def test_benchmarking():
    """Test benchmark suite."""
    from agentuniverse.agent.context.benchmark.benchmark_suite import (
        ContextBenchmarkSuite
    )

    context_manager = ContextManagerManager().get_instance_obj("default_context_manager")
    suite = ContextBenchmarkSuite(context_manager)

    # Check result structure
    assert result.test_name == "full_suite"
    assert result.metrics is not None
    assert result.timestamp is not None

    # Check metrics
    metrics = result.metrics
    assert 0 <= metrics.multi_turn_coherence <= 1
    assert 0 <= metrics.compression_ratio <= 1
    assert 0 <= metrics.information_loss <= 1
    assert 0 <= metrics.retrieval_precision <= 1
    assert metrics.average_latency_ms >= 0
    assert metrics.memory_usage_mb >= 0

    # Check scoring
    score = metrics.get_score()
    assert 0 <= score <= 100

    print(f"✅ Benchmark test passed")
    print(f"   Score: {score:.1f}/100")
    print(f"   Coherence: {metrics.multi_turn_coherence:.3f}")
    print(f"   Compression: {metrics.compression_ratio:.1%}")

## Performance Targets (vs Cursor/Claude)

| Metric | Target | Production Minimum |
|--------|--------|-------------------|
| Multi-turn coherence | >0.85 | >0.80 |
| Compression ratio | 60-80% | 50-80% |
| Information loss | <10% | <15% |
| Retrieval precision | >0.90 | >0.85 |
| Add latency | <50ms | <100ms |
| Search latency | <100ms | <200ms |
| Memory usage | <500MB | <750MB |
| Overall score | >85/100 | >75/100 |

## Troubleshooting

### Issue: Low coherence score

**Symptoms**: `multi_turn_coherence < 0.8`

**Solutions**:
- Increase compression quality threshold
- Use CRITICAL priority for important context
- Enable VERSION_BOTH conflict resolution
- Increase context window size

### Issue: High latency

**Symptoms**: `latency > 100ms`

**Solutions**:
- Enable caching in storage tier
- Use truncate compression for speed
- Reduce top_k in searches
- Optimize token counting

### Issue: Memory exhaustion

**Symptoms**: `memory_usage > 500MB`

**Solutions**:
- Enable warm/cold storage tiers
- Reduce TTL for ephemeral segments
- Increase compression aggressiveness
- Implement proactive pruning
