### Agent Design

#### Agent Definition Pattern
```markdown
# Agent Name

## Role
[Clear role definition]

## Domain Expertise
[Areas of expertise]

## Skills & Specializations
[Detailed capabilities]

## Responsibilities
[What this agent does]

## Boundaries
[What this agent does NOT do]

## Dependencies
[Other agents this agent depends on]

## Output Format
[Expected output structure]
```

#### Agent Contract Pattern
```markdown
# Agent Contract

## Agent Identity
- Name, Type, Version

## Scope of Authority
[Final authority areas]

## Core Responsibilities
[Must-do tasks]

## Deliverables
[Required outputs]

## Boundaries
[Limitations]

## Quality Gates
[Pre/post checks]

## Collaboration Protocol
[How to work with other agents]

## Success Criteria
[When work is complete]
```

### Orchestration Patterns

#### Single Agent Execution
```python
from claude_force import AgentOrchestrator

orchestrator = AgentOrchestrator()
result = orchestrator.run_agent(
    agent_name="code-reviewer",
    task="Review auth.py for security issues",
    model="claude-3-5-sonnet-20241022"
)
```

#### Workflow Execution
```python
result = orchestrator.run_workflow(
    workflow_name="full-stack-feature",
    task="Build user authentication",
    model="claude-3-5-sonnet-20241022"
)
```

#### Agent Recommendation
```python
recommendations = orchestrator.recommend_agents(
    task="Optimize database queries",
    top_k=3
)
```

### Hooks System

#### Hook Types
1. **session-start.md**: Initialization, setup, welcome message
2. **pre-run.md**: Pre-execution validation, task checks
3. **post-run.md**: Quality validation, scorecard checks

#### Hook Pattern
```markdown
# Hook Name

## Purpose
[What this hook does]

## Trigger
[When it runs]

## Actions
[Steps to perform]

## Validation
[Checks to perform]

## Error Handling
[What to do if validation fails]
```

### Validators (Governance)

#### Standard Validators
1. **scorecard-validator**: Quality checklist enforcement
2. **write-zone-guard**: Context tracking enforcement
3. **secret-scan**: Credential leak prevention
4. **diff-discipline**: Minimal change enforcement
5. **format-lint**: Output format validation
6. **hierarchy-governance**: Agent boundary enforcement

#### Validator Pattern
```markdown
# Validator Name

## Purpose
[What this validator checks]

## Validation Rules
[Specific rules to enforce]

## Pass Criteria
[When validation passes]

## Fail Actions
[What to do on failure]
```

## Overview
[What this skill provides]

## Capabilities
[What you can do with this skill]

## Patterns
[Common usage patterns]

## Examples
[Code examples]

## Best Practices

```

### Slash Commands

#### Command Structure
```markdown
# /command-name

## Purpose
[What this command does]

## Usage
/command-name <arg1> [--option]

## Parameters
- arg1: Required. Description
- --option: Optional. Description

## Steps
1. Step 1
2. Step 2
3. Step 3

## Output
[What the command produces]

## Examples
/command-name value1
/command-name value2 --option=val
```

#### Common Commands
- `/new-task`: Create task from template
- `/run-agent <name>`: Execute specific agent
- `/run-workflow <name>`: Execute workflow
- `/validate-output`: Run quality validators
- `/status`: Show session progress

### Workflows

#### Workflow Pattern
```json
"workflows": {
  "full-stack-feature": [
    "frontend-architect",
    "backend-architect",
    "database-architect",
    "code-reviewer",
    "document-writer-expert"
  ]
}
```

#### Workflow Best Practices
1. **Sequential Execution**: Each agent builds on previous work
2. **Context Passing**: Write Zones track progress
3. **Clear Handoffs**: Each agent specifies next steps
4. **Quality Gates**: Validators run between agents
5. **Error Recovery**: Fallback strategies defined

### MCP (Model Context Protocol)

#### MCP Server Implementation
```python
from claude_force import MCPServer

server = MCPServer()
server.start(host="0.0.0.0", port=8080)
```

#### MCP Endpoints
- `GET /capabilities`: List all agents, workflows, skills
- `POST /execute`: Execute agent or workflow
- `GET /health`: Health check

#### MCP Integration
```python
from claude_force import MCPClient

client = MCPClient("http://localhost:8080")
capabilities = client.list_capabilities()
result = client.execute_agent("code-reviewer", task="Review code")
```

### Headless Mode

#### Execution Modes
1. **Python API**: Direct Python integration
2. **CLI**: Command-line usage
3. **REST API**: HTTP endpoints
4. **MCP Server**: Model Context Protocol
5. **GitHub Actions**: CI/CD integration

#### Python API Pattern
```python
from claude_force import AgentOrchestrator

orchestrator = AgentOrchestrator(
    config_path=".claude/claude.json",
    anthropic_api_key="sk-..."
)

result = orchestrator.run_agent("code-reviewer", "Review file.py")
```

#### REST API Pattern
```python
from fastapi import FastAPI
from claude_force import AgentOrchestrator

app = FastAPI()
orchestrator = AgentOrchestrator()

@app.post("/agents/run")
async def run_agent(request: AgentRequest):
    result = orchestrator.run_agent(
        agent_name=request.agent_name,
        task=request.task
    )
    return {"status": "success", "output": result.output}
```

## Implementation Patterns

### Pattern 1: Create New Agent
```python
def create_agent(
    name: str,
    role: str,
    domains: List[str],
    expertise: Dict[str, List[str]],
    output_dir: str = ".claude"
):
    """Create a new agent with definition and contract."""

    # Create agent definition
    agent_md = f"""# {name.replace('-', ' ').title()} Agent

## Role
{role}

## Domain Expertise
{chr(10).join(f'- {domain}' for domain in domains)}

## Skills & Specializations
{format_expertise(expertise)}

## Responsibilities
[Define responsibilities]

## Boundaries (What This Agent Does NOT Do)
[Define boundaries]

## Dependencies
[List dependencies]

## Output Format
[Define output structure]
"""

    # Create agent contract
    contract = f"""# {name} - Agent Contract

## Agent Identity
- **Name**: {name}
- **Type**: {role}
- **Version**: 1.0.0

## Scope of Authority
[Define authority]

## Core Responsibilities
[List responsibilities]

## Deliverables
[List deliverables]

[... rest of contract ...]
"""

    # Write files
    Path(f"{output_dir}/agents/{name}.md").write_text(agent_md)
    Path(f"{output_dir}/contracts/{name}.contract").write_text(contract)

    # Update claude.json
    update_claude_json(name, domains)
```

### Pattern 2: Semantic Agent Selection
```python
from claude_force import SemanticAgentSelector

selector = SemanticAgentSelector()
matches = selector.select_agents(
    task="Review authentication code for SQL injection",
    top_k=3,
    min_confidence=0.5
)

for match in matches:
    print(f"Agent: {match.agent_name}")
    print(f"Confidence: {match.confidence:.2f}")
    print(f"Reasoning: {match.reasoning}")
```

### Pattern 3: Performance Tracking
```python
from claude_force import PerformanceTracker

tracker = PerformanceTracker()

# Automatic tracking
result = orchestrator.run_agent("code-reviewer", "Review code")

# View metrics
metrics = tracker.get_agent_metrics("code-reviewer")
print(f"Average duration: {metrics['avg_duration']:.2f}s")
print(f"Total cost: ${metrics['total_cost']:.4f}")
print(f"Success rate: {metrics['success_rate']:.1%}")
```
