# HerClaw Agent System

A comprehensive self-improving AI agent framework that combines the autonomous capabilities of Hermes Agent into a unified OpenClaw skill. This system enables AI agents to learn from experience, create and refine skills autonomously, maintain persistent memory across sessions, and continuously evolve their capabilities through reinforcement learning.

# Part 1: Learning Loop System

The Learning Loop is the core engine that enables autonomous learning from experience. It operates as a continuous cycle of experience collection, pattern extraction, skill synthesis, and validation.

## Architecture

### Phase 1: Experience Collection

Every interaction, tool call, and decision point is captured as structured trajectory data:

```python
class ExperienceCollector:
    """
    Collects and structures interaction experiences for learning.
    """
    def __init__(self, storage_backend):
        self.storage = storage_backend
        self.trajectory_buffer = []

    def capture_interaction(self, interaction):
        """

        Args:
            interaction: Dict containing:
                - user_input: The user's request
                - context: Environmental context (files, state, etc.)
                - actions: List of actions taken

        self.trajectory_buffer.append(experience)

# Usage Examples

## Basic Usage

```python
from herclaw_agentsystem import HerClawAgentSystem

# Initialize the complete system
system = HerClawAgentSystem(
    config_path="herclaw-agentsystem-config.yaml",
    llm_client=openai_client,
    storage_path="./data"
)

# Start all subsystems
system.start()

# Process an interaction
result = system.process_interaction(
    user_input="Help me analyze the sales data",
    context={"project": "Q4 Analysis", "files": ["sales.csv"]}
)

# The system will automatically:
# 1. Store the interaction in memory
# 2. Extract patterns if applicable
# 3. Create skills if patterns emerge
# 4. Evolve based on performance
# 5. Nudge itself for continuous improvement
```

## Manual Control

```python
# Trigger manual learning cycle
system.learning_loop.run_cycle()

# Create a skill manually
skill = system.skill_creation.create_skill(
    name="data_analysis_workflow",
    description="Standard data analysis workflow",
    pattern=identified_pattern
)

# Trigger evolution
system.self_evolution.trigger_evolution(
    target="data_analysis_workflow",
    type="skill_refinement"
)

# Query memory
context = system.memory.retrieve_context(
    user_id="user_123",
    query="What did we discuss about sales?"
)

# Trigger a nudge
system.nudge_system.trigger_nudge('memory_persistence', priority='high')
```

## Integration with Existing Agent

```python
# Integrate with an existing agent framework
class MyAgent:
    def __init__(self):
        self.herclaw = HerClawAgentSystem(config)
        self.herclaw.start()
    
    def process(self, user_input, context=None):
        # Get context from memory
        memory_context = self.herclaw.memory.retrieve_context(
            user_id=context.get('user_id'),
            query=user_input
        )
        
        # Check for applicable skills
        applicable_skills = self.herclaw.skills.find_applicable(
            user_input, context
        )
        
        # Process with skills and context
        response = self._generate_response(
            user_input, 
            context=memory_context,
            skills=applicable_skills
        )
        
        # Store interaction
        self.herclaw.memory.store_interaction({
            'user_input': user_input,
            'agent_response': response,
            'context': context,
            'outcome': {'success': True}
        })
        
        return response
```

# Best Practices

## 1. Learning Loop
- Start with simple, well-defined task types
- Monitor skill creation closely in the beginning
- Set appropriate pattern thresholds to avoid noise
- Regularly review auto-generated skills

## 2. Skill Creation
- Focus on quality over quantity
- Define clear trigger conditions
- Include comprehensive instructions
- Test skills thoroughly before deployment

## 3. Self-Evolution
- Use conservative rollout strategies
- Monitor health metrics continuously
- Maintain rollback capability
- Document all evolution decisions

## 4. Persistent Memory
- Implement appropriate retention policies
- Use efficient embedding models
- Balance context size with token limits
- Respect user privacy

## 5. Nudge System
- Don't overwhelm with too many nudges
- Monitor effectiveness and adjust
- Allow user customization
- Handle failures gracefully

# Troubleshooting

| Subsystem | Issue | Cause | Solution |
|-----------|-------|-------|----------|
| Learning Loop | No skills being created | Insufficient experiences | Increase interaction volume or lower min_experiences |
| Learning Loop | Low confidence skills | Inconsistent patterns | Review pattern extraction settings |
| Skill Creation | Skills not triggering | Trigger conditions too narrow | Broaden trigger definitions |
| Skill Creation | Validation failures | Incomplete instructions | Enhance instruction generation |
| Self-Evolution | Evolution not improving | Poor reward signals | Review and adjust reward functions |
| Self-Evolution | Deployment rollbacks | Health check failures | Adjust thresholds or fix underlying issues |
| Memory | Slow retrieval | Large collection | Add indexes, reduce n_results |
| Memory | Irrelevant results | Poor embeddings | Fine-tune embedding model |
| Nudge System | Too many nudges | Low thresholds | Increase min_intervals |
| Nudge System | Nudges ignored | Low effectiveness | Review and revise templates |
