### CoV Protocol Integration

The agent injects the full Chain-of-Verification system prompt, ensuring:

1. **Step 0**: Question restatement for clarity
2. **Step 1**: Initial answer generation
3. **Step 2**: Verification question generation (3-5 questions)
4. **Step 3**: Independent verification of each question
5. **Step 4**: Revised final answer with incorporated insights

---

## Commands

### Core Verification Commands

- `COV_CHAT [question]` - Full CoV verification through Ollama API

- `DEEP_VERIFY [question]` - Extended verification with more questions
- `STREAM_COV [question]` - Streaming CoV response

### API Management

- `TEST_CONNECTION` - Verify Ollama API connectivity
- `SHOW_CONFIG` - Display current configuration
- `SET_MODEL [model]` - Change the model (e.g., gpt-oss:120b)
- `SET_TIMEOUT [seconds]` - Adjust request timeout

### Batch Operations

- `BATCH_VERIFY [questions...]` - Verify multiple questions
- `COMPARE_ANSWERS [q1] [q2]` - Compare verification outputs
- `EXPORT_RESULTS [format]` - Export to JSON/Markdown

---

## Configuration

### Environment Variables

```bash
# Required
export OLLAMA_API_KEY="your-api-key-here"

# Optional (with defaults)
export OLLAMA_MODEL="gpt-oss:120b"
export OLLAMA_API_URL="https://ollama.com/api/chat"
export OLLAMA_TIMEOUT="120"
```

### Model Options

| Model | Use Case | Speed | Quality |
|-------|----------|-------|---------|
| gpt-oss:120b | General verification | Medium | High |
| gpt-oss:70b | Fast verification | Fast | Good |
| custom:model | Specialized tasks | Varies | Varies |

---

## API Call Structure

### Request Format

```json
{
  "model": "gpt-oss:120b",

      "role": "system",
      "content": "[CoV System Prompt]"
    },
    {
      "role": "user",
      "content": "[User Question]"
    }
  ],
  "stream": false
}
```

### Headers

```
Authorization: Bearer $OLLAMA_API_KEY
Content-Type: application/json
```

}
```

---

## Usage Examples

### Direct Invocation

```bash
# Full CoV verification
use ollama-cov-agent: COV_CHAT "What's the best database for time-series data?"

# Quick verification
use ollama-cov-agent: QUICK_VERIFY "Is Redis suitable for session storage?"

# Streaming response
use ollama-cov-agent: STREAM_COV "Explain microservices vs monolith"
```

### CLI Integration

```bash
# Via coc command
coc ollama-cov "Your verification question"
coc ocov-quick "Quick question"
coc ocov-stream "Streaming question"
```

### Shell Library

```bash
# Source the library
source ~/craig-o-code/lib/ollama-cov/client.sh

# Use functions directly
ollama_cov_chat "Your question here"
ollama_quick_verify "Quick question"
ollama_cov_chat_stream "Streaming question"
```

### Python Library

```python
from lib.ollama_cov.client import OllamaCoVClient

client = OllamaCoVClient()
response = client.chat("Your verification question")
print(response.content)
```

---

## CoV System Prompt

The agent uses this system prompt for all verification requests:

```
Chain-of-Verification Reasoning Protocol

You are an AI system operating under a Chain-of-Verification (CoV)
reasoning framework. Your primary objective is to produce accurate,
well-reasoned, and bias-resistant outputs by explicitly separating
initial reasoning from independent verification.

```

---

## Error Handling

### Common Errors

| Error | Cause | Resolution |
|-------|-------|------------|
| 401 Unauthorized | Invalid API key | Check OLLAMA_API_KEY |
| 429 Rate Limited | Too many requests | Implement backoff |
| 500 Server Error | API issues | Retry with backoff |
| Timeout | Long response | Increase OLLAMA_TIMEOUT |

### Retry Strategy

```
Attempt 1: Immediate
Attempt 2: Wait 2 seconds
Attempt 3: Wait 4 seconds
Attempt 4: Wait 8 seconds
Fail: Report error to user
```

---

## Integration with CoV Orchestrator

The Ollama CoV Agent can work alongside the main cov-orchestrator:

### Routing Rules

| Question Type | Route To | Reason |
|---------------|----------|--------|
| Simple factual | ollama-cov-agent | Fast, cost-effective |
| Complex reasoning | cov-orchestrator | Full worker delegation |
| High-stakes | cov-orchestrator | Maximum verification |
| Batch processing | ollama-cov-agent | API efficiency |

### Hybrid Workflow

## Performance Metrics

Track these metrics for optimization:

- **Latency**: Time from request to response
- **Token Usage**: Input/output token counts
- **Cost**: Per-request cost tracking
- **Success Rate**: Successful verifications
- **Quality Score**: Verification completeness

---

## Best Practices

### Do

- Use for straightforward verification tasks
- Leverage streaming for long responses
- Cache common verification patterns
- Monitor API usage and costs
- Test connection before batch operations

### Don't

- Use for extremely complex multi-domain questions
- Skip error handling in production
- Hardcode API keys in scripts
- Ignore rate limiting signals
- Use for sensitive data without encryption

---

## Quick Reference

```bash
# Test connection
use ollama-cov-agent: TEST_CONNECTION

# Full verification
use ollama-cov-agent: COV_CHAT "Your question"

# Quick verification
use ollama-cov-agent: QUICK_VERIFY "Your question"

# Show config
use ollama-cov-agent: SHOW_CONFIG
```

Deliver fast, accurate, bias-resistant verification through the Ollama API.
