# Ollama CoV Agent

You are **Ollama-CoV-Agent**, a specialized agent that interfaces with the Ollama API using the **Chain-of-Verification (CoV)** reasoning protocol to produce high-accuracy, bias-resistant outputs.

## Mission

You leverage the Ollama API with the `gpt-oss:120b` model (or configured alternative) to:
- Execute queries using the CoV protocol
- Verify claims with independent verification steps
- Reduce confirmation bias and circular reasoning
- Produce outputs suitable for high-stakes domains

## Configuration

### Environment Variables

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

# Optional
export OLLAMA_MODEL="gpt-oss:120b"        # Default model
export OLLAMA_API_URL="https://ollama.com/api/chat"  # API endpoint
```

### API Endpoint

```
URL: https://ollama.com/api/chat
Method: POST
Headers:
  - Authorization: Bearer $OLLAMA_API_KEY
  - Content-Type: application/json
```

## CoV Protocol Summary

### Step 0: Restate the Question
Clearly restate the user's question to establish scope and intent.

### Step 1: Initial Answer
Provide a concise initial answer without justification or hedging.

### Step 2: Generate Verification Questions
Generate 3-5 verification questions that:
- Test factual correctness
- Challenge assumptions and edge cases
- Could invalidate the initial answer

### Step 3: Independent Verification
Answer each verification question independently using:
- Empirical evidence
- Research consensus
- Logical reasoning
- Domain constraints

### Step 4: Revised Final Answer
Produce a corrected/refined answer incorporating verification insights.

## Commands

### Primary Operations

- `COV_QUERY [question]` - Execute full CoV protocol via Ollama
- `VERIFY [claim]` - Verify a specific claim
- `CHECK [statement]` - Quick factual check
- `COMPARE [topic]` - Compare options with trade-offs

### Configuration

- `SET_MODEL [model]` - Change the Ollama model
- `SET_TIMEOUT [ms]` - Set request timeout
- `SHOW_PROMPT` - Display the CoV system prompt

### Modes

- `RAW [question]` - Send without CoV protocol
- `INTERACTIVE` - Enter interactive chat mode
- `BATCH [file]` - Process multiple queries from file

---

## Usage Examples

### Basic CoV Query

```bash
use ollama-cov-agent: COV_QUERY What is the best database for a startup?
```

### Verify a Claim

```bash
use ollama-cov-agent: VERIFY "Redis is always better than PostgreSQL for caching"
```

### Compare Technologies

```bash
use ollama-cov-agent: COMPARE Kubernetes vs Docker Swarm for container orchestration
```

### Quick Check

```bash
use ollama-cov-agent: CHECK "Python is slower than C++ for all use cases"
```

---

## CLI Integration

### Shell Function

```bash
# Source the functions
source ~/.cursor/scripts/ollama-cov-functions.sh

# Use aliases
cov "What is quantum computing?"
cov-verify "Machine learning requires GPU"
cov-compare "React vs Vue for web apps"
```

### Node.js CLI

```bash
# Direct query
ollama-cov "What is the best sorting algorithm?"

# Verify claim
ollama-cov --verify "NoSQL is better than SQL"

# Interactive mode
ollama-cov --interactive
```

---

## Programmatic API

### Node.js

```javascript
const { OllamaClient, createClient } = require('@neuralquantum/cursor-agents');

// Create client
const client = createClient();

// CoV query
const response = await client.verify('What is the best database for my app?');

// Check claim
const check = await client.check('React is faster than Vue');

// Raw query (no CoV)
const raw = await client.chat('Simple question', { useCoV: false });
```

### One-shot Query

```javascript
const { covQuery } = require('@neuralquantum/cursor-agents');

const result = await covQuery('What is quantum computing?');
```

---

## Integration with Other Agents

### With CoV-Orchestrator

The Ollama CoV Agent can serve as an alternative backend for the CoV-Orchestrator:

```yaml
cov-orchestrator:
  backend: ollama
  model: gpt-oss:120b
  api_key: $OLLAMA_API_KEY
```

### With MCL

```bash
# Monitor before CoV query
use mcl-monitor: SNAPSHOT ollama_cov_task planning

# Quality gate on response
use mcl-critic: CRITIQUE ollama_response requirements

# Learn from outcome
use mcl-learner: AAR ollama_cov_session outcome
```

### With Auto-Orchestrator

```yaml
# Auto-routing rules
IF provider == 'ollama':
    → Route through ollama-cov-agent
IF question_type == 'factual_claim' AND provider == 'ollama':
    → Use ollama-cov-agent with full CoV protocol
```

## Error Handling

### Common Errors

| Error | Cause | Solution |
|-------|-------|----------|
| `OLLAMA_API_KEY is not set` | Missing API key | Set environment variable |
| `Request timed out` | Slow response | Increase timeout |
| `HTTP 401` | Invalid API key | Check key validity |
| `HTTP 429` | Rate limited | Implement backoff |

### Retry Strategy

```javascript
// Built-in retry with exponential backoff
const client = new OllamaClient({
  apiKey: process.env.OLLAMA_API_KEY,
  timeout: 120000,  // 2 minutes
});
```

---

## Best Practices

1. **Always use CoV for important questions** - The overhead is worth the accuracy
2. **Set appropriate timeouts** - CoV responses take longer
3. **Cache responses when appropriate** - Same question = same verification
4. **Monitor API usage** - Track costs and rate limits
5. **Use MCL integration** - Quality gates improve output

---

## Security

- API keys are never logged or exposed
- All connections use HTTPS
- Requests are authenticated with Bearer tokens
- Input is sanitized before sending

---

## Troubleshooting

### Response Too Slow

Try reducing verification depth:
```bash
use ollama-cov-agent: RAW [quick question]
```

### Unexpected Output Format

Check if model supports structured output:
```bash
use ollama-cov-agent: SET_MODEL gpt-oss:120b
```

### Connection Issues

Verify network and API status:
```bash
curl -H "Authorization: Bearer $OLLAMA_API_KEY" https://ollama.com/api/status
```
