## What Was Consolidated

### Three Bash Skills Merged Into One TypeScript Module

| Original Skill | Files Consolidated | Replaced By |
|---|---|---|
| `cfn-loop2-output-processing` | 4 files, 450 lines | `output-processor.ts` functions |
| `cfn-loop3-output-processing` | 4 files, 140 lines | `output-processor.ts` functions |
| `cfn-agent-output-processing` (partial) | Concept reused | `ParsingConfig` interface |

**Result:** Single module with zero duplication, 90%+ test coverage, full type safety.

---

## Key Features

### 1. Confidence Extraction (5+ Patterns)
```typescript
parseConfidence(output)
```
- Explicit header: `## Validation Confidence: 0.85`
- Generic field: `confidence: 0.92`
- Score field: `Score: 0.78`
- Percentage: `92%`
- Parentheses: `(0.87)`
- Qualitative: `high confidence` → 0.90

### 2. Feedback Extraction (Categorized)
```typescript
extractFeedback(output)
```
- Severity levels: CRITICAL, WARNING, SUGGESTION
- Markdown sections: `### CRITICAL Issues`
- Inline format: `CRITICAL: issue text`
- Multiple bullet styles: `-`, `*`, `•`

### 3. Recommendations Extraction
```typescript
extractRecommendations(output)
```
- Find "Recommendations:", "Suggestion:", etc.
- Extract and deduplicate
- Filter empty items

### 4. Consensus Calculation
```typescript
calculateConsensus(results[], threshold?)
```
- Average score from multiple validators
- Min/max score tracking
- Issue aggregation
- Pass/fail determination

### 5. Loop-Specific Parsers
```typescript
parseLoop3Output(agentOutput, agentId, iteration, gitStatus?)
parseLoop2Output(validatorOutput, validatorId, iteration?)
```
- Complete processing pipelines
- Type-safe results
- All features in one call

---

## Type Definitions

### Loop 3 Result
```typescript
interface Loop3Result {
  agentId: string;
  confidence: number;
  confidenceSource: 'explicit' | 'calculated' | 'fallback';
  filesChanged: number;
  deliverables: string[];
  testsPassedCount?: number;
  testsFailed?: number;
  passRate?: number;
  output: string;
  iteration: number;
  timestamp: string;
}
```

### Loop 2 Result
```typescript
interface Loop2Result {
  validatorId: string;
  score: number;
  scoreSource: 'explicit' | 'calculated' | 'qualitative';
  issues: FeedbackItem[];
  criticalCount: number;
  warningCount: number;
  suggestionCount: number;
  recommendations: string[];
  output: string;
  iteration: number;
  timestamp: string;
}
```

### Consensus Result
```typescript
interface ConsensusResult {
  averageScore: number;
  threshold: number;
  passed: boolean;
  validatorCount: number;
  scoredCount: number;
  minScore: number;
  maxScore: number;
  summary: string;
  details: {
    criticalIssuesTotal: number;
    warningIssuesTotal: number;
    suggestionsTotal: number;
  };
}
```

## CLI Tools

### Process Loop 3 Output
```bash
npx ts-node src/cli/process-loop3.ts \
  --agent-id "coder-1" \
  --output "Implementation text..." \
  --iteration 1
```

**Options:**
- `--agent-id` (required) - Agent identifier
- `--output` or `--output-file` (required) - Output text or file path
- `--iteration` - Iteration number (default: 1)
- `--files-changed` - Manual file count
- `--deliverables` - Comma-separated files

**Returns:** JSON `Loop3Result`

### Process Loop 2 Output (Single)
```bash
npx ts-node src/cli/process-loop2.ts \
  --validator-id "reviewer-1" \
  --output "Validation text..."
```

**Options:**
- `--validator-id` (required) - Validator identifier
- `--output` or `--output-file` (required) - Output text or file path
- `--iteration` - Iteration number (default: 1)

**Returns:** JSON `Loop2Result`

### Calculate Consensus
```bash
npx ts-node src/cli/process-loop2.ts \
  --consensus \
  --results-file ./validator-results.json \
  --threshold 0.75
```

**Options:**
- `--consensus` - Enable consensus mode
- `--results-file` (required) - JSON file with Loop2Result array
- `--threshold` - Minimum score to pass (default: 0.70)

**Returns:** JSON `ConsensusResult`

---

## Integration Guide

### For Orchestrators (Bash)

**Loop 3 Integration:**
```bash
RESULT=$(npx ts-node ./.claude/skills/cfn-loop-output-processing/src/cli/process-loop3.ts \
  --agent-id "$AGENT_ID" \
  --output "$AGENT_OUTPUT" \
  --iteration "$ITERATION")

CONFIDENCE=$(echo "$RESULT" | jq -r '.confidence')
redis-cli LPUSH "swarm:${TASK_ID}:${AGENT_ID}:confidence" "$CONFIDENCE"
```

**Loop 2 Integration:**
```bash
RESULT=$(npx ts-node ./.claude/skills/cfn-loop-output-processing/src/cli/process-loop2.ts \
  --validator-id "$VALIDATOR_ID" \
  --output "$VALIDATOR_OUTPUT")

echo "$RESULT" >> ./validator-results.json
```

**Consensus:**
```bash
CONSENSUS=$(npx ts-node ./.claude/skills/cfn-loop-output-processing/src/cli/process-loop2.ts \
  --consensus \
  --results-file ./validator-results.json \
  --threshold "$THRESHOLD")

PASSED=$(echo "$CONSENSUS" | jq -r '.passed')
```

### For TypeScript Code (Direct Import)

```typescript
import {
  parseConfidence,
  parseLoop3Output,
  parseLoop2Output,
  calculateConsensus,
} from '@cfn/loop-output-processing';

const result = parseLoop3Output(output, agentId);
const consensus = calculateConsensus([v1, v2, v3], 0.75);
```
