## 🧠 Self-Learning Protocol (v3.0.0-alpha.1)

### Before Each PR Task: Learn from History

```typescript
// 1. Search for similar past PR solutions
const similarPRs = await reasoningBank.searchPatterns({
  task: `Manage PR for ${currentPR.title}`,
  k: 5,
  minReward: 0.8
});

if (similarPRs.length > 0) {
  console.log('📚 Learning from past successful PRs:');
  similarPRs.forEach(pattern => {
    console.log(`- ${pattern.task}: ${pattern.reward} success rate`);
    console.log(`  Merge strategy: ${pattern.output.mergeStrategy}`);
    console.log(`  Conflicts resolved: ${pattern.output.conflictsResolved}`);
    console.log(`  Critique: ${pattern.critique}`);
  });

  // Apply best practices from successful PR patterns
  const bestPractices = similarPRs
    .filter(p => p.reward > 0.9)
    .map(p => p.output);
}

// 2. Learn from past PR failures
const failedPRs = await reasoningBank.searchPatterns({
  task: 'PR management',
  onlyFailures: true,
  k: 3
});

if (failedPRs.length > 0) {
  console.log('⚠️  Avoiding past PR mistakes:');
  failedPRs.forEach(pattern => {
    console.log(`- ${pattern.critique}`);
    console.log(`  Failure reason: ${pattern.output.failureReason}`);
  });
}
```

### During PR Management: GNN-Enhanced Code Search

```typescript
// Use GNN to find related code changes (+12.4% better accuracy)
const buildPRGraph = (prFiles) => ({
  nodes: prFiles.map(f => f.filename),
  edges: detectDependencies(prFiles),
  edgeWeights: calculateChangeImpact(prFiles),
  nodeLabels: prFiles.map(f => f.path)
});

const relatedChanges = await agentDB.gnnEnhancedSearch(
  prEmbedding,
  {
    k: 10,
    graphContext: buildPRGraph(pr.files),
    gnnLayers: 3
  }
);

console.log(`Found related code with ${relatedChanges.improvementPercent}% better accuracy`);

// Smart conflict detection with GNN
const potentialConflicts = await agentDB.gnnEnhancedSearch(
  currentChangesEmbedding,
  {
    k: 5,
    graphContext: buildConflictGraph(),
    gnnLayers: 2
  }
);
```

### Multi-Agent Coordination with Attention

```typescript
// Coordinate review decisions using attention consensus (better than voting)
const coordinator = new AttentionCoordinator(attentionService);

const reviewDecisions = [
  { agent: 'security-reviewer', decision: 'approve', confidence: 0.95 },
  { agent: 'code-quality-reviewer', decision: 'request-changes', confidence: 0.85 },
  { agent: 'performance-reviewer', decision: 'approve', confidence: 0.90 }
];

const consensus = await coordinator.coordinateAgents(
  reviewDecisions,
  'flash' // 2.49x-7.47x faster
);

console.log(`Review consensus: ${consensus.consensus}`);
console.log(`Confidence: ${consensus.confidence}`);
console.log(`Agent influence: ${consensus.attentionWeights}`);

// Intelligent merge decision based on attention consensus
if (consensus.consensus === 'approve' && consensus.confidence > 0.85) {
  await mergePR(pr, consensus.suggestedStrategy);
}
```

### After PR Completion: Store Learning Patterns

```typescript
// Store successful PR pattern for future learning
const prMetrics = {
  filesChanged: pr.files.length,
  linesAdded: pr.additions,
  linesDeleted: pr.deletions,
  conflictsResolved: conflicts.length,
  reviewRounds: reviews.length,
  mergeTime: mergeTimestamp - createTimestamp,
  testsPassed: allTestsPass,
  securityChecksPass: securityPass
};

await reasoningBank.storePattern({
  sessionId: `pr-manager-${prId}-${Date.now()}`,
  task: `Manage PR: ${pr.title}`,
  input: JSON.stringify({ title: pr.title, files: pr.files, context: pr.description }),
  output: JSON.stringify({
    mergeStrategy: mergeStrategy,
    conflictsResolved: conflicts,
    reviewerConsensus: consensus,
    metrics: prMetrics
  }),
  reward: calculatePRSuccess(prMetrics),
  success: pr.merged && allTestsPass,
  critique: selfCritiquePRManagement(pr, reviews),
  tokensUsed: countTokens(prOutput),
  latencyMs: measureLatency()
});
```

## 🎯 GitHub-Specific Optimizations

### Smart Merge Decision Making

```typescript
// Learn optimal merge strategies from past PRs
const mergeHistory = await reasoningBank.searchPatterns({
  task: 'PR merge strategy',
  k: 20,
  minReward: 0.85
});

const strategy = analyzeMergePatterns(mergeHistory, currentPR);
// Returns: 'squash', 'merge', 'rebase' based on learned patterns
```

### Attention-Based Conflict Resolution

```typescript
// Use attention to focus on most impactful conflicts
const conflictPriorities = await agentDB.flashAttention(
  conflictEmbeddings,
  codeContextEmbeddings,
  codeContextEmbeddings
);

// Resolve conflicts in order of attention scores
const sortedConflicts = conflicts.sort((a, b) =>
  conflictPriorities[b.id] - conflictPriorities[a.id]
);
```

### GNN-Enhanced Review Coordination

```typescript
// Build PR review graph
const reviewGraph = {
  nodes: reviewers.concat(prFiles),
  edges: buildReviewerFileRelations(),
  edgeWeights: calculateExpertiseScores(),
  nodeLabels: [...reviewers.map(r => r.name), ...prFiles.map(f => f.path)]
};

// Find optimal reviewer assignments with GNN
const assignments = await agentDB.gnnEnhancedSearch(
  prEmbedding,
  {
    k: 3, // Top 3 reviewers
    graphContext: reviewGraph,
    gnnLayers: 2
  }
);
```

## Usage Patterns

### 1. Create and Manage PR with Swarm Coordination
```javascript
// Initialize review swarm
mcp__claude-flow__swarm_init { topology: "mesh", maxAgents: 4 }
mcp__claude-flow__agent_spawn { type: "reviewer", name: "Code Quality Reviewer" }
mcp__claude-flow__agent_spawn { type: "tester", name: "Testing Agent" }
mcp__claude-flow__agent_spawn { type: "coordinator", name: "PR Coordinator" }

// Create PR and orchestrate review
mcp__github__create_pull_request {
  owner: "ruvnet",
  repo: "ruv-FANN",
  title: "Integration: claude-code-flow and ruv-swarm",
  head: "integration/claude-code-flow-ruv-swarm",
  base: "main",
  body: "Comprehensive integration between packages..."
}

// Orchestrate review process
mcp__claude-flow__task_orchestrate {
  task: "Complete PR review with testing and validation",
  strategy: "parallel",
  priority: "high"
}
```

### 2. Automated Multi-File Review
```javascript
// Get PR files and create parallel review tasks
mcp__github__get_pull_request_files { owner: "ruvnet", repo: "ruv-FANN", pull_number: 54 }

// Create coordinated reviews
mcp__github__create_pull_request_review {
  owner: "ruvnet",
  repo: "ruv-FANN", 
  pull_number: 54,
  body: "Automated swarm review with comprehensive analysis",
  event: "APPROVE",
  comments: [
    { path: "package.json", line: 78, body: "Dependency integration verified" },
    { path: "src/index.js", line: 45, body: "Import structure optimized" }
  ]
}
```

### 3. Merge Coordination with Testing
```javascript
// Validate PR status and merge when ready
mcp__github__get_pull_request_status { owner: "ruvnet", repo: "ruv-FANN", pull_number: 54 }

// Merge with coordination
mcp__github__merge_pull_request {
  owner: "ruvnet",
  repo: "ruv-FANN",
  pull_number: 54,
  merge_method: "squash",
  commit_title: "feat: Complete claude-code-flow and ruv-swarm integration",
  commit_message: "Comprehensive integration with swarm coordination"
}

// Post-merge coordination
mcp__claude-flow__memory_usage {
  action: "store",
  key: "pr/54/merged",
  value: { timestamp: Date.now(), status: "success" }
}
```

## Batch Operations Example

### Complete PR Lifecycle in Parallel:
```javascript
[Single Message - Complete PR Management]:
  // Initialize coordination
  mcp__claude-flow__swarm_init { topology: "hierarchical", maxAgents: 5 }
  mcp__claude-flow__agent_spawn { type: "reviewer", name: "Senior Reviewer" }
  mcp__claude-flow__agent_spawn { type: "tester", name: "QA Engineer" }
  mcp__claude-flow__agent_spawn { type: "coordinator", name: "Merge Coordinator" }
  
  // Create and manage PR using gh CLI
  Bash("gh pr create --repo :owner/:repo --title '...' --head '...' --base 'main'")
  Bash("gh pr view 54 --repo :owner/:repo --json files")
  Bash("gh pr review 54 --repo :owner/:repo --approve --body '...'")
  
  
  // Execute tests and validation
  Bash("npm test")
  Bash("npm run lint")
  Bash("npm run build")
  
  // Track progress
  TodoWrite { todos: [
    { id: "review", content: "Complete code review", status: "completed" },
    { id: "test", content: "Run test suite", status: "completed" },
    { id: "merge", content: "Merge when ready", status: "pending" }
  ]}
```

## Best Practices

### 1. **Always Use Swarm Coordination**

- Assign specialized agents for different review aspects
- Use memory for cross-agent coordination

### 2. **Batch PR Operations**
- Combine multiple GitHub API calls in single messages
- Parallel file operations for large PRs
- Coordinate testing and validation simultaneously

### 3. **Intelligent Review Strategy**
- Automated conflict detection and resolution
- Multi-agent review for comprehensive coverage
- Performance and security validation integration

### 4. **Progress Tracking**
- Use TodoWrite for PR milestone tracking
- GitHub issue integration for project coordination
- Real-time status updates through swarm memory

## Integration with Other Modes

### Works seamlessly with:
- `/github issue-tracker` - For project coordination
- `/github branch-manager` - For branch strategy
- `/github ci-orchestrator` - For CI/CD integration
- `/sparc reviewer` - For detailed code analysis
- `/sparc tester` - For comprehensive testing

## Error Handling

### Automatic retry logic for:
- Network failures during GitHub API calls
- Merge conflicts with intelligent resolution
- Test failures with automatic re-runs
- Review bottlenecks with load balancing

### Swarm coordination ensures:
- No single point of failure
- Automatic agent failover
- Progress preservation across interruptions
- Comprehensive error reporting and recovery
