## Overview

The **Auto-Remediation System** enables AI to autonomously resolve infrastructure issues by executing write operations on your systems. This is a **production-grade** implementation with extensive safety checks, human oversight, and continuous learning.

### Key Features

✅ **Safety-First**: Auto-remediation **disabled by default**  
✅ **Reliability Scoring**: Multi-factor confidence calculation (0-100%)  
✅ **Human Feedback**: Continuous learning from user feedback  
✅ **Pattern Recognition**: Learns from similar issues  
✅ **Approval Workflow**: Critical actions require human approval  
✅ **Full Audit Trail**: Every action logged with rollback capability  
✅ **Progressive Automation**: Decisions improve over time based on success rate

---

## Safety First Design

### 🛡️ Default State: DISABLED

```python
# Example: Ticket submission
{
    "ticket_id": "INC-001",
    "description": "Problem description",
    "enable_auto_remediation": false  # ← DEFAULT: Disabled
}
```

**Auto-remediation must be explicitly enabled for each ticket.**

### Safety Layers

1. **Explicit Enablement**: Must opt-in per ticket
2. **Reliability Thresholds**: Minimum confidence required
3. **Action Classification**: Safe vs. Critical operations
4. **Pre-execution Checks**: System health, backups, rate limits
5. **Human Approval**: Required for low-reliability or critical actions
6. **Post-execution Validation**: Verify success
7. **Rollback Capability**: Undo on failure

### Action Classification

```python
class RemediationAction(str, enum.Enum):
    READ_ONLY = "read_only"           # No changes (default)
    SAFE_WRITE = "safe_write"          # Non-destructive (restart, clear cache)
    CRITICAL_WRITE = "critical_write"  # Potentially destructive (delete, modify)
```

**Critical actions ALWAYS require human approval**, regardless of confidence.

---

## Reliability Scoring System

### Multi-Factor Calculation

The reliability score (0-100%) is calculated from **4 components**:

```python
Reliability Score = (
    AI Confidence    × 25% +  # Model's own confidence
    Human Feedback   × 30% +  # Historical feedback quality
    Success History  × 25% +  # Past resolution success rate
    Pattern Match    × 20%    # Similarity to known patterns
)
```

### Component Details

#### 1. AI Confidence (25%)
- Direct from Claude Sonnet 4.5
- Based on documentation quality and analysis certainty
- Range: 0-1 converted to 0-100%

#### 2. Human Feedback (30%)
- Weighted by recency (recent feedback = more weight)
- Considers:
  - Positive/Negative/Neutral feedback type
  - Star ratings (1-5)
  - Resolution accuracy
  - Action effectiveness

```python
feedback_score = (
    positive_feedback_rate × 100 +
    average_rating / 5 × 100
) / 2
```

#### 3. Historical Success (25%)
- Success rate in same category (last 6 months)
- Formula: `resolved_tickets / total_tickets × 100`

#### 4. Pattern Match (20%)
- Similarity to known, resolved patterns
- Requires ≥3 similar tickets for pattern
- Boosts score if pattern has positive feedback

### Confidence Levels

| Score Range | Level     | Description |
|-------------|-----------|-------------|
| 90-100%     | Very High | Excellent track record, safe to auto-execute |
| 75-89%      | High      | Good reliability, may require approval |
| 60-74%      | Medium    | Moderate confidence, approval recommended |
| 0-59%       | Low       | Low confidence, manual review required |

### Example Breakdown

```json
{
  "overall_score": 87.5,
  "confidence_level": "high",
  "breakdown": {
    "ai_confidence": "92%",
    "human_validation": "85%",
    "success_history": "90%",
    "pattern_recognition": "82%"
  }
}
```

---

## Human Feedback Loop

### Feedback Collection

After each ticket resolution, collect structured feedback:

```python
{
  "ticket_id": "INC-001",
  "feedback_type": "positive|negative|neutral",
  "rating": 5,  # 1-5 stars
  "was_helpful": true,
  "resolution_accurate": true,
  "actions_worked": true,
  
  # Optional detailed feedback
  "comment": "Great resolution!",
  "what_worked": "The restart fixed it",
  "what_didnt_work": null,
  "suggestions": "Could add more details",
  
  # If AI failed, what actually worked?
  "actual_resolution": "Had to increase memory instead",
  "actual_actions_taken": [...],
  "time_to_resolve": 30.0  # minutes
}
```

### Feedback Impact

1. **Immediate**: Updates ticket reliability score
2. **Pattern Learning**: Strengthens/weakens pattern eligibility
3. **Future Decisions**: Influences similar ticket handling
4. **Auto-remediation Eligibility**: Pattern becomes eligible after:
   - ≥5 occurrences
   - ≥85% positive feedback rate
   - ≥85% average reliability score

### Feedback Analytics

Track feedback trends:
- Positive/Negative/Neutral distribution
- Average ratings by category
- Resolution accuracy trends
- Action success rates

## Decision Engine

### Decision Flow

```
1. Check: Auto-remediation enabled for ticket?
   ├─ NO → Skip auto-remediation
   └─ YES → Continue

2. Get applicable policy for category
   ├─ No policy → Require manual approval
   └─ Policy exists → Continue

3. Classify action risk level
   ├─ READ_ONLY → Low risk
   ├─ SAFE_WRITE → Medium risk
   └─ CRITICAL_WRITE → High risk

4. Check confidence & reliability thresholds
   ├─ Below minimum → Reject
   └─ Above minimum → Continue

5. Perform safety checks
   ├─ Pre-checks failed → Reject
   └─ All passed → Continue

6. Check pattern eligibility
   ├─ Unknown pattern → Require approval
   └─ Known good pattern → Continue

7. Determine approval requirement
   ├─ Reliability ≥ auto_approve_threshold → Auto-approve
   ├─ Critical action → Require approval
   └─ Otherwise → Follow policy

8. Execute or await approval
```

### Decision Example

```json
{
  "allowed": true,
  "action_type": "safe_write",
  "requires_approval": false,
  "reasoning": [
    "All checks passed",
    "Auto-approved: reliability 92% >= 90%"
  ],
  "safety_checks": {
    "time_window_ok": true,
    "rate_limit_ok": true,
    "backup_available": true,
    "system_healthy": true,
    "all_passed": true
  },
  "risk_level": "medium"
}
```

## Auto-Remediation Execution

### Execution Flow

```python
async def execute_remediation(ticket, actions, decision):
    # 1. Verify decision allows execution
    if not decision['allowed']:
        return error
    
    # 2. Check approval if required
    if decision['requires_approval']:
        if not has_approval(ticket):
            return "awaiting_approval"
    
    # 3. Execute each action with safety
    for action in actions:
        # Pre-execution check
        pre_check = await check_system_health()
        if not pre_check.passed:
            rollback()
            return error
        
        # Execute action via MCP
        result = await execute_via_mcp(action)
        
        # Post-execution verification
        post_check = await verify_success()
        if not post_check.passed:
            rollback()
            return error
        
        # Log action
        log_remediation(action, result)
    
    return success
```

## Pattern Learning

### Pattern Identification

```python
# Generate pattern signature
pattern = {
    'category': 'network',
    'key_terms': ['vlan', 'connectivity', 'timeout'],
    'hash': sha256(signature)
}
```

### Pattern Statistics

Tracked for each pattern:
- **Occurrence count**: How many times seen
- **Success/failure counts**: Resolution outcomes
- **Feedback distribution**: Positive/negative/neutral
- **Average confidence**: Mean AI confidence
- **Average reliability**: Mean reliability score
- **Auto-remediation success rate**: % of successful auto-fixes

### Pattern Eligibility

Pattern becomes eligible for auto-remediation when:

```python
if (
    pattern.occurrence_count >= 5 and
    pattern.positive_feedback_rate >= 0.85 and
    pattern.avg_reliability_score >= 85.0 and
    pattern.auto_remediation_success_rate >= 0.85
):
    pattern.eligible_for_auto_remediation = True
```

### Pattern Evolution

```
Initial State:
├─ occurrence_count: 1
├─ eligible_for_auto_remediation: false
└─ Manual resolution only

After 5+ occurrences with good feedback:
├─ occurrence_count: 7
├─ positive_feedback_rate: 0.85
├─ avg_reliability_score: 87.0
├─ eligible_for_auto_remediation: true
└─ Can trigger auto-remediation

After 20+ occurrences:
├─ occurrence_count: 24
├─ auto_remediation_success_rate: 0.92
├─ Very high confidence
└─ Auto-remediation without approval
```

  for: 15m
  annotations:
    summary: "Auto-remediation failure rate > 20%"
```

---

## Best Practices

### 1. Start Conservative

- Enable auto-remediation for **low-risk categories** first (e.g., cache clearing)
- Set high thresholds initially (reliability ≥ 90%)
- Require approvals for first 20-30 occurrences
- Monitor closely and adjust based on results

### 2. Gradual Rollout

```
Week 1-2: Enable for 5% of tickets
Week 3-4: Increase to 20% if success rate > 90%
Week 5-6: Increase to 50% if success rate > 85%
Week 7+:  Full rollout with dynamic thresholds
```

### 3. Category-Specific Policies

Different categories need different thresholds:

| Category | Min Reliability | Auto-Approve | Reason |
|----------|----------------|--------------|--------|
| Cache | 75% | 85% | Low risk, frequent |
| Network | 85% | 90% | Medium risk |
| Storage | 90% | 95% | High risk |
| Security | 95% | Never | Critical, always approve |

### 4. Human in the Loop

- Always collect feedback, even for successful auto-remediations
- Review logs weekly
- Adjust thresholds based on feedback trends
- Disable patterns with declining success rates

### 5. Continuous Learning

- System improves over time through feedback
- Patterns with 20+ occurrences and 90%+ success → Very high confidence
- Allow system to become more autonomous as reliability proves out
- But maintain human oversight for critical operations

---

## Troubleshooting

### Auto-remediation not executing

**Check:**
1. Is `enable_auto_remediation: true` in ticket?
2. Is there an active policy for the category?
3. Does confidence/reliability meet thresholds?
4. Are safety checks passing?
5. Does pattern meet eligibility requirements?

**Debug:**
```bash
# Check decision
curl http://localhost:8000/api/v1/tickets/TICKET-ID | jq '.remediation_decision'

# Check logs
curl http://localhost:8000/api/v1/tickets/TICKET-ID/remediation-logs
```

### Low reliability scores

**Causes:**
- Insufficient historical data
- Negative feedback on category
- Low pattern match confidence
- Recent failures in category

**Solutions:**
- Collect more feedback
- Review and improve resolutions
- Wait for more data points
- Manually resolve similar tickets successfully

### Pattern not becoming eligible

**Requirements not met:**
- Need ≥5 occurrences
- Need ≥85% positive feedback
- Need ≥85% average reliability

**Action:**
- Continue resolving similar tickets
- Ensure feedback is being collected
- Check pattern stats: `GET /api/v1/patterns`

---

## Future Enhancements

- **Multi-step reasoning**: Complex workflows spanning multiple systems
- **Predictive remediation**: Fix issues before they cause incidents
- **A/B testing**: Compare different resolution strategies
- **Reinforcement learning**: Optimize actions based on outcomes
- **Natural language explanations**: Better transparency in decisions
- **Cross-system orchestration**: Coordinated actions across infrastructure

---

## Summary

The **Auto-Remediation System** is designed for **safe, gradual automation** of infrastructure issue resolution:

1. ✅ **Disabled by default** - explicit opt-in per ticket
2. ✅ **Multi-factor reliability** - comprehensive confidence calculation
3. ✅ **Human feedback loop** - continuous learning and improvement
4. ✅ **Pattern recognition** - learns from similar issues
5. ✅ **Safety first** - extensive checks, approval workflows, rollback
6. ✅ **Progressive automation** - system becomes more autonomous over time
7. ✅ **Full observability** - complete audit trail and analytics

**Start small, monitor closely, scale gradually, and let the system learn.**
