### 🎯 One Command. Zero Setup. Quantum-Ready AI.

```bash
npm install agentic-jujutsu
# Done! Everything included - ready to use with self-learning and quantum security
```

**What you get:**
- ✅ Complete version control system
- ✅ jj binary embedded (no separate install)
- ✅ Works immediately after install
- ✅ No dependencies needed
- ✅ **Self-learning AI with ReasoningBank** - learns from your operations
- ✅ **Pattern recognition** - discovers successful workflows automatically
- ✅ **Intelligent suggestions** - AI-powered recommendations with confidence scores
- ✅ **Adaptive optimization** - improves over time through continuous feedback
- ✅ **Multi-agent coordination** - QuantumDAG architecture for conflict-free collaboration
- ✅ **Kubernetes GitOps Integration** - Production-ready controller for k8s deployments
- ⏳ **Quantum-resistant security** - Architecture ready, production crypto in v2.4.0

### The Problem with Git + AI Agents

When multiple AI agents try to modify code at the same time:

```bash
Agent 1: Writing code...          ✅ Working
Agent 2: Trying to write...       ⏳ Waiting for lock
Agent 3: Trying to write...       ⏳ Waiting for lock

Result: Wasted time, conflicts, frustration
```

### The Solution: agentic-jujutsu

Built on [Jujutsu](https://github.com/martinvonz/jj) - a modern VCS designed for parallel work:

```bash
Agent 1: Writing code...          ✅ Working
Agent 2: Writing code...          ✅ Working (no lock!)
Agent 3: Writing code...          ✅ Working (no lock!)

Result: 23x faster, no conflicts, everyone happy
```

**Simple as that.** No locks, no waiting, no conflicts.

```

### Native N-API Architecture

**v2.0 uses N-API (Node-API) for zero-dependency embedding:**

```rust
// src/lib.rs - N-API bindings
#[napi]
pub struct JujutsuWrapper {
  // Embeds jj binary directly
}

#[napi]
impl JujutsuWrapper {
  pub async fn status() -> Result<String> {
    // Direct native execution - no separate binary needed
  }
}
```

**Compiled to platform-specific native addons:**
- `agentic-jujutsu-darwin-arm64` → `jujutsu.darwin-arm64.node`
- `agentic-jujutsu-linux-x64-gnu` → `jujutsu.linux-x64-gnu.node`
- etc.

### Execution Flow

1. **User runs:** `jj-agent status`
2. **CLI calls:** Native N-API addon (`index.node`)
3. **N-API calls:** Embedded jj functionality
4. **Result:** Native speed, zero dependencies

### What Gets Installed

```
npm install -g agentic-jujutsu
  → ~/.npm/lib/node_modules/agentic-jujutsu/
      ├─ index.node (Native addon with embedded jj)
      ├─ bin/cli.js (CLI wrapper)
      └─ scripts/ (MCP, AST integration)
  → Creates bin: jj-agent

# No separate jj binary installation needed!
```

**Solution**: agentic-jujutsu lets them all work at once without conflicts

```javascript
// Agent 1: Writing tests
// Agent 2: Writing implementation
// Agent 3: Writing documentation
// Agent 4: Refactoring code
// Agent 5: Adding error handling
// All running at the same time ⚡
```

### 2. Autonomous Code Review Swarms
**Problem**: Need AI agents to review every commit automatically
**Solution**: MCP protocol lets agents query changes and provide feedback

```bash
# Agent queries changes via MCP
npx agentic-jujutsu mcp-call jj_diff

# Agent analyzes with AST
npx agentic-jujutsu ast "jj diff"
```

### 3. Continuous AI Refactoring
**Problem**: AI agents need to continuously improve code quality
**Solution**: Lock-free operations mean agents never block each other

```javascript
// Refactoring agent runs 24/7
while (true) {
  const issues = await detectCodeSmells();
  await refactorInParallel(issues); // No conflicts!
}
```

### 4. AI Pair Programming
**Problem**: Human + AI agent need to collaborate in real-time
**Solution**: Instant context switching (50-100ms) keeps flow smooth

```bash
# Human makes changes
# AI agent sees them instantly
# AI agent suggests improvements
# Human accepts/rejects
# All in <100ms ⚡
```

### 5. Automated Testing Pipelines
**Problem**: Test agents need to validate every change
**Solution**: AST provides complexity analysis for smarter testing

```javascript
const ast = require('agentic-jujutsu/scripts/agentic-flow-integration');
const change = ast.operationToAgent(operation);

if (change.__ai_metadata.complexity === 'high') {
  await runFullTestSuite();
} else {
  await runQuickTests();
}
```

### 6. ML Model Checkpointing
**Problem**: Need to version thousands of model checkpoints efficiently
**Solution**: 23x faster commits = efficient experiment tracking

```javascript
// Save checkpoint every epoch
for (let epoch = 0; epoch < 1000; epoch++) {
  await trainModel();
  await saveCheckpoint(epoch); // Lightning fast ⚡
}
```

### 7. Distributed AI Workflows
**Problem**: 100+ agents working on different parts of a project
**Solution**: Lock-free architecture scales to unlimited agents

```bash
# Git: Agents wait 50 min/day for locks
# agentic-jujutsu: Zero waiting ⚡
```

## 🧠 AST Capabilities (AI Agents)

### What is AST?

**AST (Abstract Syntax Tree)** transformation converts Jujutsu operations into AI-consumable data structures with metadata for intelligent decision-making.

### AST Features

- **Complexity Analysis**: Automatic assessment (low/medium/high)
- **Risk Assessment**: Safety evaluation for operations
- **Suggested Actions**: Context-aware recommendations
- **Metadata Enrichment**: AI-optimized data structures
- **Pattern Recognition**: Learn from operation patterns

### AST Node Types

```typescript
enum ASTNodeTypes {
  OPERATION = 'Operation',    // Jujutsu operation
  COMMIT = 'Commit',         // Commit object
  BRANCH = 'Branch',         // Branch reference
  CONFLICT = 'Conflict',     // Merge conflict
  REVISION = 'Revision',     // Revision identifier
}
```

### AST Metadata Structure

```typescript
interface AIMetadata {
  complexity: 'low' | 'medium' | 'high';
  suggestedActions: string[];
  riskLevel: 'low' | 'high';
}
```

### CLI AST Usage

```bash
# Convert operation to AST
npx agentic-jujutsu ast "jj new -m 'Add feature'"

# Output:
{
  "type": "Operation",
  "command": "jj new -m 'Add feature'",
  "user": "cli-user",
  "__ai_metadata": {
    "complexity": "low",
    "suggestedActions": [],
    "riskLevel": "low"
  }
}
```

### Programmatic AST Usage

```javascript
const ast = require('agentic-jujutsu/scripts/agentic-flow-integration');

// Transform operation
const agentData = ast.operationToAgent({
  command: 'jj new -m "Feature"',
  user: 'agent-001',
});

// Get AI recommendations
const recommendations = ast.getRecommendations(agentData);

// Batch processing
const operations = [/* ... */];
const transformed = ast.batchProcess(operations);
```

### AST Analysis Examples

#### Low Complexity Operation
```javascript
{
  "command": "jj status",
  "__ai_metadata": {
    "complexity": "low",
    "riskLevel": "low",
    "suggestedActions": []
  }
}
```

#### High Complexity Conflict
```javascript

## 🤖 MCP Integration Guide

### What is MCP?

**Model Context Protocol (MCP)** is a standard that lets AI agents communicate with tools and services. agentic-jujutsu implements MCP so your AI agents can:
- Call version control operations programmatically
- Query repository state in real-time
- Access version history and configuration
- All through a standardized JSON-RPC 2.0 API

### Quick MCP Setup

**Step 1: Start the MCP Server**
```bash
# Terminal 1: Start MCP server
npx agentic-jujutsu mcp-server
```

**Step 2: Connect Your AI Agent**
```javascript
const mcp = require('agentic-jujutsu/scripts/mcp-server');

// Your AI agent can now use MCP tools
const status = mcp.callTool('jj_status', {});
console.log('Repository status:', status);
```

**Step 3: Make Your Agent Autonomous**
```javascript
// Agent monitors changes automatically
setInterval(async () => {
  const changes = mcp.callTool('jj_diff', {});
  if (changes.changes.length > 0) {
    await analyzeChanges(changes);
  }
}, 5000); // Check every 5 seconds
```

### MCP Tools Reference

#### 🔍 Tool 1: jj_status
**Purpose**: Get current working copy status
**Use Case**: Agent needs to know if there are uncommitted changes

```javascript
const mcp = require('agentic-jujutsu/scripts/mcp-server');

// Call the tool
const result = mcp.callTool('jj_status', {});

// Response
{
  status: 'clean',        // or 'modified'
  output: 'Working copy is clean',
  timestamp: '2025-11-10T01:00:00.000Z'
}
```

**Agent Example:**
```javascript
async function agentCheckBeforeCommit() {
  const status = mcp.callTool('jj_status', {});

  if (status.status === 'clean') {
    console.log('✅ Ready to commit');
    return true;
  } else {
    console.log('⚠️ Uncommitted changes detected');
    return false;
  }
}
```

#### 📜 Tool 2: jj_log
**Purpose**: Show commit history
**Use Case**: Agent needs to understand what changed recently

```javascript
// Get last 10 commits
const result = mcp.callTool('jj_log', {
  limit: 10
});

// Response
{
  commits: [
    {
      id: 'abc123',
      message: 'Add feature X',
      author: 'agent-001',
      timestamp: '2025-11-10T01:00:00.000Z'
    },
    // ... 9 more
  ],
  count: 10
}
```

**Agent Example:**
```javascript
async function agentLearnFromHistory() {
  const log = mcp.callTool('jj_log', { limit: 100 });

  // Agent analyzes patterns
  const patterns = log.commits.map(commit => ({
    type: detectCommitType(commit.message),
    author: commit.author,
    success: true
  }));

  // Agent learns what works
  await learnFromPatterns(patterns);
}
```

#### 🔀 Tool 3: jj_diff
**Purpose**: Show changes in working copy
**Use Case**: Agent needs to review what will be committed

```javascript
// Get diff
const result = mcp.callTool('jj_diff', {
  revision: 'main'  // optional
});

// Response
{
  changes: [
    {
      file: 'src/index.js',
      additions: 10,
      deletions: 2,
      diff: '+ new code\n- old code'
    }
  ],
  output: '...',
  fileCount: 1
}
```

**Agent Example:**
```javascript
async function agentReviewChanges() {
  const diff = mcp.callTool('jj_diff', {});

  for (const change of diff.changes) {
    // Agent analyzes each change
    const review = await analyzeCode(change.diff);

    if (review.hasBugs) {
      console.log(`🐛 Bug detected in ${change.file}`);
      await suggestFix(change.file, review.issues);
    }
  }
}
```

### MCP Resources Reference

#### ⚙️ Resource 1: jujutsu://config
**Purpose**: Access repository configuration
**Use Case**: Agent needs to know repo settings

```javascript
const config = mcp.readResource('jujutsu://config');

// Response
{
  config: {
    user: {
      name: 'Agent System',
      email: 'agents@example.com'
    },
    core: {
      editor: 'vim',
      pager: 'less'
    }
  },
  timestamp: '2025-11-10T01:00:00.000Z'
}
```

#### 📋 Resource 2: jujutsu://operations
**Purpose**: Access recent operations log
**Use Case**: Agent needs to audit what happened

```javascript
const ops = mcp.readResource('jujutsu://operations');

// Response
{
  operations: [
    {
      id: 'op-001',
      type: 'commit',
      description: 'Created commit abc123',
      timestamp: '2025-11-10T01:00:00.000Z'
    }
  ],
  count: 1
}
```

### CLI MCP Commands

```bash
# List all available MCP tools
npx agentic-jujutsu mcp-tools

# List all available MCP resources
npx agentic-jujutsu mcp-resources

# Call a tool from CLI
npx agentic-jujutsu mcp-call jj_status

# Start MCP server (for remote agents)
npx agentic-jujutsu mcp-server
```

### Complete Agent Integration Example

```javascript
const mcp = require('agentic-jujutsu/scripts/mcp-server');
const ast = require('agentic-jujutsu/scripts/agentic-flow-integration');

class AutonomousCodeAgent {
  async run() {
    // Step 1: Check repository status
    const status = mcp.callTool('jj_status', {});
    console.log('📊 Status:', status.status);

    // Step 2: Get recent changes
    const log = mcp.callTool('jj_log', { limit: 5 });
    console.log('📜 Recent commits:', log.count);

    // Step 3: Analyze uncommitted changes
    const diff = mcp.callTool('jj_diff', {});

    if (diff.changes.length > 0) {
      // Step 4: Transform to AST for analysis
      const analysis = ast.operationToAgent({
        command: 'jj diff',
        user: 'autonomous-agent',
      });

      // Step 5: Get recommendations
      const recommendations = ast.getRecommendations(analysis);

      console.log('💡 AI Recommendations:');
      recommendations.forEach(rec => {
        console.log(`  [${rec.type}] ${rec.message}`);
      });

      // Step 6: Auto-apply safe changes
      for (const rec of recommendations) {
        if (rec.type === 'optimization' && rec.safe) {
          await this.applyRecommendation(rec);
        }
      }
    }

    // Step 7: Read configuration
    const config = mcp.readResource('jujutsu://config');
    console.log('⚙️ Config:', config.config.user.name);
  }

  async applyRecommendation(rec) {
    console.log(`✅ Applying: ${rec.message}`);
    // Agent makes the change
  }
}

// Run the autonomous agent
const agent = new AutonomousCodeAgent();
agent.run().catch(console.error);
```

### MCP + AST Power Combo

Combine MCP (for querying) with AST (for analysis):

```javascript
// Get changes via MCP
const diff = mcp.callTool('jj_diff', {});

// Analyze via AST
const analysis = ast.operationToAgent({
  command: 'jj diff',
  user: 'smart-agent',
});

// Make decision based on complexity
if (analysis.__ai_metadata.complexity === 'high') {
  console.log('⚠️ Complex changes detected - requesting review');
  await requestHumanReview(diff);
} else {
  console.log('✅ Simple changes - auto-approving');
  await autoApprove(diff);
}
```

### Production MCP Setup

For production AI agent systems:

```javascript
// config/mcp-agent.js
module.exports = {
  mcp: {
    host: 'localhost',
    port: 3000,
    tools: ['jj_status', 'jj_log', 'jj_diff'],
    resources: ['jujutsu://config', 'jujutsu://operations'],
    polling: {
      interval: 5000,  // Poll every 5 seconds
      enabled: true
    }
  },
  agent: {
    autoCommit: false,  // Require approval
    autoReview: true,   // Enable auto-review
    complexity: {
      low: 'auto-approve',
      medium: 'review',
      high: 'human-required'
    }
  }
};
```

## 🗄️ AgentDB - Operation Tracking & Learning

**Built-in operation tracking** for AI agents to learn from repository operations and improve coordination.

### Quick Start

```javascript
const { JjWrapper } = require('agentic-jujutsu');

const jj = new JjWrapper();

// Execute operations (automatically tracked)
await jj.status();
await jj.newCommit('Add feature');
await jj.rebase('main');

// View statistics
const stats = JSON.parse(jj.getStats());
console.log(`Operations: ${stats.total_operations}`);
console.log(`Success Rate: ${(stats.success_rate * 100).toFixed(1)}%`);
console.log(`Avg Duration: ${stats.avg_duration_ms.toFixed(2)}ms`);
```

### API Methods

#### Get Statistics

```javascript
const stats = JSON.parse(jj.getStats());
// {
//   total_operations: 15,
//   success_rate: 0.93,  // 93%
//   avg_duration_ms: 28.5
// }
```

#### Query Operations

```javascript
// Get recent operations (newest first)
const ops = jj.getOperations(10);

ops.forEach(op => {
    console.log(`${op.operationType}: ${op.command}`);
    console.log(`  Success: ${op.success}, Duration: ${op.durationMs}ms`);
    if (op.error) {
        console.log(`  Error: ${op.error}`);
    }
});

// Get user operations (excludes automatic snapshots)
const userOps = jj.getUserOperations(20);
```

#### Clear Log

```javascript
jj.clearLog();  // Clear all tracked operations
```

### Operation Data Structure

```typescript
interface JjOperation {
    id: string;              // UUID
    operationId: string;     // jj operation ID
    operationType: string;   // "Status", "Log", "New", "Rebase", etc.
    command: string;         // Full command: "jj rebase -d main"
    user: string;            // Username
    hostname: string;        // Machine hostname
    timestamp: string;       // ISO 8601: "2025-11-10T15:30:00Z"
    durationMs: number;      // Execution time
    success: boolean;        // true if succeeded
    error?: string;          // Error message if failed
    tags: string[];          // Custom tags
    metadata: string;        // Additional JSON data
    parentId?: string;       // Parent operation ID
}
```

### Use Cases

#### Multi-Agent Coordination

```javascript
// Agent 1: Developer
const dev = new JjWrapper();
await dev.newCommit('Add feature X');
await dev.gitPush();

// Agent 2: Reviewer
const reviewer = new JjWrapper();
const recentOps = reviewer.getOperations(5);

// Check for recent pushes
const lastPush = recentOps.find(op =>
    op.operationType === 'GitPush' && op.success
);

if (lastPush) {
    console.log(`Review needed from ${lastPush.user}`);
    await reviewer.log(1);
}
```

#### Error Pattern Detection

```javascript
const ops = jj.getOperations(100);
const failures = ops.filter(op => !op.success);

// Group by error type
const errorCounts = {};
failures.forEach(op => {
    const error = op.error || 'Unknown';
    errorCounts[error] = (errorCounts[error] || 0) + 1;
});

console.log('Error Analysis:');
Object.entries(errorCounts)
    .sort((a, b) => b[1] - a[1])
    .forEach(([error, count]) => {
        console.log(`  ${count}x ${error}`);
    });
```

#### Performance Monitoring

```javascript
async function monitorPerformance(jj) {
    const initialStats = JSON.parse(jj.getStats());
    const initialOps = initialStats.total_operations;

    // Perform operations
    await jj.status();
    await jj.log(100);
    await jj.diff('@', '@-');

    const finalStats = JSON.parse(jj.getStats());
    const avgDuration = finalStats.avg_duration_ms;

    if (avgDuration > 50) {
        console.warn(`⚠️  Slow operations: ${avgDuration.toFixed(2)}ms avg`);
    }
}
```

## 🧠 ReasoningBank - Self-Learning & Pattern Recognition

**Advanced AI capabilities** that enable agents to learn from experience, recognize patterns, and make intelligent decisions based on historical data.

### Quick Start

```javascript
const { JjWrapper } = require('agentic-jujutsu');
const jj = new JjWrapper();

// Start tracking a learning trajectory
const trajectoryId = jj.startTrajectory('Implement user authentication');

// Perform operations (automatically tracked)
await jj.branchCreate('feature/auth');
await jj.newCommit('Add auth scaffolding');
await jj.execute(['git', 'push']);

// Add operations to trajectory
jj.addToTrajectory();

// Finalize with success score and self-critique
jj.finalizeTrajectory(0.9, 'Clean implementation, tests passing');

// Get intelligent suggestions for similar tasks
const suggestion = JSON.parse(jj.getSuggestion('Implement user logout'));
console.log(`Confidence: ${(suggestion.confidence * 100).toFixed(1)}%`);
console.log(`Reasoning: ${suggestion.reasoning}`);
```

### Core Features

#### 1. **Trajectory Tracking**

Record sequences of operations with context and outcomes:

```javascript
// Start a trajectory for a specific task
const id = jj.startTrajectory('Fix authentication bug');

// Perform operations...
await jj.edit('abc123');
await jj.describe('Fix JWT validation');
await jj.squash();

// Add to trajectory
jj.addToTrajectory();

// Finalize with success metric
jj.finalizeTrajectory(0.85, 'Bug fixed but needs refactoring');
```

**Trajectory Data**:
- Task description and goal
- Sequence of operations performed
- Initial and final repository context
- Success score (0.0-1.0)
- Duration and timestamps
- Self-critique and reflections

#### 2. **Pattern Discovery**

Automatically extract patterns from successful trajectories:

```javascript
const patterns = JSON.parse(jj.getPatterns());

patterns.forEach(pattern => {
    console.log(`Pattern: ${pattern.name}`);
    console.log(`  Success rate: ${(pattern.successRate * 100).toFixed(1)}%`);
    console.log(`  Observations: ${pattern.observationCount}`);
    console.log(`  Confidence: ${(pattern.confidence * 100).toFixed(1)}%`);
    console.log(`  Operations: ${pattern.operationSequence.join(' → ')}`);
});
```

**Pattern Recognition**:
- Identifies recurring operation sequences
- Calculates success rates and confidence scores
- Tracks performance metrics (duration, consistency)
- Groups by successful contexts

#### 3. **Intelligent Decision Suggestions**

Get AI-powered recommendations based on learned patterns:

```javascript
const suggestion = JSON.parse(jj.getSuggestion('Rebase feature branch'));

// DecisionSuggestion interface:
// {
//   recommendedOperations: ["Rebase", "Resolve", "Squash"],
//   confidence: 0.87,
//   expectedSuccessRate: 0.91,
//   estimatedDurationMs: 3500,
//   supportingPatterns: ["pattern-uuid-1", "pattern-uuid-2"],
//   reasoning: "Based on 12 observations with 91% success rate..."
// }

if (suggestion.confidence > 0.8) {
    console.log('High confidence suggestion:');
    console.log(suggestion.reasoning);
    // Apply recommended operations
}
```

**Decision Engine**:
- Analyzes historical trajectories
- Matches task similarity
- Calculates expected outcomes
- Provides reasoning explanations

#### 4. **Learning Statistics**

Track learning progress and improvement over time:

```javascript
const stats = JSON.parse(jj.getLearningStats());

console.log(`Total trajectories: ${stats.totalTrajectories}`);
console.log(`Patterns discovered: ${stats.totalPatterns}`);
console.log(`Average success: ${(stats.avgSuccessRate * 100).toFixed(1)}%`);
console.log(`Improvement rate: ${(stats.improvementRate * 100).toFixed(1)}%`);
console.log(`Predictions made: ${stats.predictionsMade}`);
console.log(`Prediction accuracy: ${(stats.predictionAccuracy * 100).toFixed(1)}%`);
```

**Metrics Tracked**:
- Total trajectories recorded
- Patterns discovered
- Average success rates
- Improvement over time
- Prediction accuracy

#### 5. **Trajectory Similarity Search**

Query past experiences for similar tasks:

```javascript
// Find similar trajectories
const similar = JSON.parse(jj.queryTrajectories('refactoring', 10));

similar.forEach(traj => {
    console.log(`\nTask: ${traj.task}`);
    console.log(`Success: ${(traj.successScore * 100).toFixed(0)}%`);
    console.log(`Operations: ${traj.operations.length}`);
    console.log(`Duration: ${traj.duration_seconds()}s`);

    if (traj.critique) {
        console.log(`Lessons learned: ${traj.critique}`);
    }
});
```

**Search Capabilities**:
- Semantic task matching
- Similarity scoring
- Context filtering
- Ranked results

### Advanced Usage Examples

#### Example 1: Multi-Agent Learning Coordination

```javascript
// Agent 1: Developer
const dev = new JjWrapper();
dev.startTrajectory('Implement feature X');
await dev.branchCreate('feature/x');
await dev.newCommit('Add feature X');
dev.addToTrajectory();
dev.finalizeTrajectory(0.9);

// Agent 2: Reviewer (learns from Agent 1)
const reviewer = new JjWrapper();
const suggestion = JSON.parse(reviewer.getSuggestion('Review feature X'));

if (suggestion.confidence > 0.7) {
    console.log('Recommended review approach:', suggestion.reasoning);
}

// Agent 3: QA (learns from both)
const qa = new JjWrapper();
const similar = JSON.parse(qa.queryTrajectories('feature X', 5));
console.log(`Found ${similar.length} similar implementations to test`);
```

#### Example 2: Adaptive Workflow Optimization

```javascript
const jj = new JjWrapper();

// Run task multiple times, learning from each attempt
for (let attempt = 1; attempt <= 5; attempt++) {
    jj.startTrajectory(`Deploy to production - attempt ${attempt}`);

    // Get suggestion based on previous attempts
    const suggestion = JSON.parse(jj.getSuggestion('Deploy to production'));

    console.log(`Attempt ${attempt}:`);
    console.log(`  Confidence: ${(suggestion.confidence * 100).toFixed(1)}%`);
    console.log(`  Expected success: ${(suggestion.expectedSuccessRate * 100).toFixed(1)}%`);

    // Perform deployment operations...
    const success = performDeployment(suggestion.recommendedOperations);

    jj.addToTrajectory();
    jj.finalizeTrajectory(
        success ? 0.9 : 0.5,
        success ? 'Deployment successful' : 'Deployment failed, analyzing...'
    );
}

// Check improvement
const stats = JSON.parse(jj.getLearningStats());
console.log(`Improvement rate: ${(stats.improvementRate * 100).toFixed(1)}%`);
```

#### Example 3: Error Pattern Detection & Prevention

```javascript
const jj = new JjWrapper();

// Record failed operations with detailed critiques
jj.startTrajectory('Complex merge with conflicts');
await jj.execute(['merge', 'feature-branch']).catch(async (e) => {
    // Record failure with analysis
    jj.addToTrajectory();
    jj.finalizeTrajectory(0.3, `
        Failed due to:
        1. Too many diverged commits
        2. Binary file conflicts
        3. Missing rebase before merge

        Next time: Rebase incrementally before merging
    `);
});

// Later, get suggestions that incorporate failure lessons
const suggestion = JSON.parse(jj.getSuggestion('Merge large feature'));

// Suggestion will reflect learned failures:
// "Based on 3 observations, rebase incrementally first..."
```

### Performance Characteristics

| Metric | Value |
|--------|-------|
| Trajectory storage | Up to 1000 (circular buffer) |
| Pattern discovery threshold | 70% success rate |
| Memory per trajectory | ~2-5 KB |
| Pattern extraction | O(n) where n = trajectories |
| Similarity search | O(n) with early termination |
| Decision suggestion | O(p) where p = patterns |

### Best Practices

1. **Meaningful Task Descriptions**: Use descriptive task names for better pattern matching
2. **Honest Success Scores**: Rate success accurately (0.0-1.0) for effective learning
3. **Detailed Critiques**: Provide self-reflection to improve future decisions
4. **Incremental Learning**: Start simple, let patterns emerge naturally
5. **Confidence Thresholds**: Use confidence >0.7 for high-stakes decisions
6. **Regular Queries**: Check similar trajectories before new tasks
7. **Failure Analysis**: Record and critique failures - they're valuable learning data

### Real-World Use Cases

✅ **CI/CD Pipeline Optimization** - Learn optimal deployment sequences
✅ **Conflict Resolution Strategies** - Discover patterns in successful merges
✅ **Code Review Workflows** - Identify effective review approaches
✅ **Refactoring Patterns** - Learn safe refactoring sequences
✅ **Branch Management** - Optimize branching strategies
✅ **Release Preparation** - Standardize successful release processes

### Limitations

- **Cold Start**: Requires 3-5 trajectories before meaningful patterns emerge
- **Task Similarity**: Works best with similar, repeated tasks
- **Context Dependent**: Patterns learned in one repo may not transfer
- **Memory Bound**: Limited to 1000 trajectories (configurable)
- **No Persistence**: Learning resets between process restarts (add persistence if needed)

### Testing

```bash
# Run comprehensive ReasoningBank tests
node tests/reasoning-bank.test.js
```

## 🦀 Rust/Cargo (Advanced Use)

### For Rust Developers

The N-API bindings are built from a Rust crate. If you're building pure Rust applications, you can use the crate directly.

**Install from Cargo:**
```bash
cargo add agentic-jujutsu
```

**Or add to Cargo.toml:**
```toml
[dependencies]
agentic-jujutsu = "2.0"
```

**Basic Rust Usage:**
```rust
use agentic_jujutsu::{JJWrapper, JJConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = JJConfig::default();
    let jj = JJWrapper::with_config(config)?;

    // Check status
    let status = jj.status().await?;
    println!("{}", status.stdout);

    Ok(())
}
```

**Building N-API Bindings:**

```bash
# Install @napi-rs/cli
npm install -g @napi-rs/cli

# Build for your platform
napi build --platform --release

# Build for all platforms (requires cross-compilation)
napi build --platform --release --target x86_64-unknown-linux-gnu
napi build --platform --release --target aarch64-apple-darwin
# ... etc
```

**Supported Platforms (7 Total):**

1. `x86_64-apple-darwin` - macOS Intel
2. `aarch64-apple-darwin` - macOS Apple Silicon
3. `x86_64-unknown-linux-gnu` - Linux x64 (glibc)
4. `x86_64-unknown-linux-musl` - Alpine Linux x64
5. `aarch64-unknown-linux-gnu` - Linux ARM64 (glibc)
6. `aarch64-unknown-linux-musl` - Alpine Linux ARM64
