## What is this?

A **npm/npx CLI tool** that lets AI agents use version control without the slowdowns of Git. Built on [Jujutsu VCS](https://github.com/martinvonz/jj) with WASM, it's 23x faster for multi-agent workflows and works everywhere Node.js runs.

**The Problem:**
```javascript
// With Git: Agents wait for locks ⏳
Agent 1: modifying code... (waiting for lock)
Agent 2: waiting... ⏳
Agent 3: waiting... ⏳
Result: 50 minutes/day wasted
```

**The Solution:**
```javascript
// With agentic-jujutsu: All agents work together ⚡
Agent 1: modifying code... ✅
Agent 2: modifying code... ✅ (no conflicts!)
Agent 3: modifying code... ✅ (no conflicts!)
Result: 23x faster, zero waiting
```

### Perfect For

## ⚡ Quick Start - Try It Now!

### Option 1: npx (Zero Installation) 🎯

```bash
# Show all commands
npx agentic-jujutsu help

# Analyze your repo for AI agents
npx agentic-jujutsu analyze

# See performance vs Git
npx agentic-jujutsu compare-git

# Get repo status
npx agentic-jujutsu status

# Convert operations to AI-readable format
npx agentic-jujutsu ast "jj new -m 'Add feature'"

# Start MCP server for AI agents
npx agentic-jujutsu mcp-server
```

**No installation, no setup - just works!** ⚡

### Option 2: Global Install (For Frequent Use)

```bash
# Step 1: Install jj binary (required for real operations)
cargo install --git https://github.com/martinvonz/jj jj-cli

# Step 2: Install agentic-jujutsu
npm install -g agentic-jujutsu

# Use shorter commands
agentic-jujutsu status  # Real jj operations!
agentic-jujutsu analyze
jj-ai help  # Alternative command name
```

**Note**: The npm package wraps the jj binary. Install jj first for real operations, or use our postinstall script with `AGENTIC_JUJUTSU_AUTO_INSTALL=true`.

### Option 3: Automatic Installation (Cargo Required)

```bash
# Enable auto-install during npm install
export AGENTIC_JUJUTSU_AUTO_INSTALL=true
npm install -g agentic-jujutsu
# Will automatically install jj via cargo if not found
```

### Option 4: Project Install (For Programmatic Use)

```bash
# Add to your project
npm install agentic-jujutsu
```

Then use in your AI agent code:
```javascript
const mcp = require('agentic-jujutsu/scripts/mcp-server');
const ast = require('agentic-jujutsu/scripts/agentic-flow-integration');

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

## 🔧 Installation

### Prerequisites

This package is a **wrapper** around jujutsu VCS. You need both:

1. **agentic-jujutsu** (npm package) - Provides CLI, WASM bindings, MCP integration
2. **jj** (binary) - The actual Jujutsu VCS

### Installation Methods

#### Method 1: Automatic (Recommended)

```bash
# Requires Cargo/Rust installed
export AGENTIC_JUJUTSU_AUTO_INSTALL=true
npm install -g agentic-jujutsu
# Automatically installs jj if not found
```

#### Method 2: Manual (Two Steps)

```bash
# Step 1: Install jj binary
cargo install --git https://github.com/martinvonz/jj jj-cli

# Step 2: Install agentic-jujutsu
npm install -g agentic-jujutsu
```

#### Method 3: Just Try It (npx)

```bash
# No installation - runs directly
npx agentic-jujutsu help
# Will show installation instructions if jj not found
```

### Installing jj Binary

Choose the best method for your platform:

```bash
# Cargo (All Platforms - Recommended)
cargo install --git https://github.com/martinvonz/jj jj-cli

# Homebrew (macOS/Linux)
brew install jj

# Nix (Linux/macOS)
nix-env -iA nixpkgs.jujutsu
```

**📖 Full installation guide**: [`docs/INSTALLATION.md`](./docs/INSTALLATION.md)

### Verification

```bash
# Check jj is installed
jj --version

# Check agentic-jujutsu is installed
agentic-jujutsu version

# Try it out
agentic-jujutsu status
```

### Three Execution Modes

1. **Node.js CLI** (`bin/cli.js`)
   - Executes real `jj` binary if installed
   - Adds AI agent features (MCP, AST, hooks)
   - Best for: Command-line usage, npx

2. **Native Rust** (`src/native.rs`)
   - Direct async-process execution
   - Maximum performance
   - Best for: Rust projects, native binaries

3. **Browser WASM** (`src/wasm.rs`)
   - Simulated operations for demos
   - No jj binary needed
   - Best for: Browser demos, testing

### What Gets Installed Where

```
npm install -g agentic-jujutsu
  → ~/.npm/lib/node_modules/agentic-jujutsu/
  → Creates bin: agentic-jujutsu, jj-ai

cargo install jj-cli
  → ~/.cargo/bin/jj
  → Real VCS binary
```

## 🎯 AI Coding Agent Use Cases

### 1. Multi-Agent Code Generation
**Problem**: 5 AI agents need to modify the same file simultaneously
**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
{
  "type": "Conflict",
  "__ai_metadata": {
    "complexity": "high",
    "riskLevel": "high",
    "suggestedActions": ["resolve_conflict", "abandon", "squash"]
  }
}
```

#### Medium Complexity Multi-Step
```javascript
{
  "command": "jj rebase -r feature -d main",
  "__ai_metadata": {
    "complexity": "medium",
    "riskLevel": "low",
    "suggestedActions": ["backup", "verify"]
  }
}
```

## 🤖 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
}
```

  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'
    }
  }
};
```

## 🎯 Exotic Usage Examples

### 1. Multi-Agent Swarm Coordination

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

// Agent swarm controller
class AgentSwarm {
  async coordinateOperation(operation) {
    // Transform to AST
    const agentData = ast.operationToAgent(operation);
    
    // Assess complexity
    if (agentData.__ai_metadata.complexity === 'high') {
      // Delegate to multiple agents
      return this.parallelExecution(operation);
    }
    
    // Single agent execution
    return this.singleExecution(operation);
  }
  
  async parallelExecution(operation) {
    // Split operation across agents
    const agents = ['agent-001', 'agent-002', 'agent-003'];
    const results = await Promise.all(
      agents.map(agent => this.executeAs(agent, operation))
    );
    
    return this.mergeResults(results);
  }
}
```

### 2. Conflict-Free Collaborative Editing

```javascript
// Multiple agents editing simultaneously
const agents = ['writer', 'reviewer', 'formatter'];

await Promise.all(agents.map(async (agent) => {
  // Each agent gets its own working copy
  const agentData = ast.operationToAgent({
    command: `jj new -m "Changes by ${agent}"`,
    user: agent,
  });
  
  // Check for conflicts (should be 0 with jj)
  const risks = agentData.__ai_metadata.riskLevel;
  console.log(`${agent} risk level: ${risks}`);
}));

// No locks, no conflicts!
```

### 3. AI-Driven Code Review Automation

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

async function aiCodeReview() {
  // Get changes
  const diff = mcp.callTool('jj_diff', {});
  
  // Analyze with AST
  const analysis = ast.operationToAgent({
    command: 'jj diff',
    user: 'review-bot',
  });
  
  // Get recommendations
  const recommendations = ast.getRecommendations(analysis);
  
  // Apply suggestions
  for (const rec of recommendations) {
    console.log(`[${rec.type}] ${rec.message}`);
    // Auto-apply safe changes
  }
}
```

### 4. Performance-Critical ML Training

```javascript
// Checkpoint ML model during training
class MLCheckpoint {
  async saveCheckpoint(epoch, model) {
    const operation = {
      command: `jj new -m "Checkpoint epoch ${epoch}"`,
      user: 'ml-trainer',
      metadata: {
        epoch,
        accuracy: model.accuracy,
        loss: model.loss,
      }
    };
    
    // Transform to AST for analysis
    const agentData = ast.operationToAgent(operation);
    
    // Fast commits (23x faster than Git)
    await this.commitCheckpoint(agentData);
  }
}
```

### 5. Distributed Task Queue with Version Control

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

const taskQueue = new Queue('vcs-tasks');

taskQueue.process(async (job) => {
  const { operation } = job.data;
  
  // Transform operation
  const agentData = ast.operationToAgent(operation);
  
  // Assess before execution
  if (agentData.__ai_metadata.riskLevel === 'high') {
    // Request human approval
    await requestApproval(agentData);
  }
  
  // Execute with full AST metadata
  return executeOperation(agentData);
});
```

### 6. Real-Time Collaboration Dashboard

```javascript
import init from 'agentic-jujutsu/web';

    const mcp = await loadMCPClient();
    
    setInterval(async () => {
      const status = mcp.callTool('jj_status', {});
      const log = mcp.callTool('jj_log', { limit: 5 });
      
      this.updateUI({
        activeAgents: this.countAgents(log),
        operations: log.commits,
        conflicts: 0, // Always 0 with jj!
      });
    }, 1000);
  }
}
```

### 7. Automated Rollback System

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

class AutoRollback {
  async monitorDeployment(deployOperation) {
    const agentData = ast.operationToAgent(deployOperation);
    
    // Set rollback trigger
    const rollbackTrigger = this.createTrigger(agentData);
    
    // Monitor health
    const health = await this.checkHealth();
    
    if (!health.ok) {
      console.log('Rolling back...');
      // Instant rollback with jj (no Git revert complexity)
      await this.rollback(agentData);
    }
  }
}
```

## 🔗 Rust/Cargo (Advanced Use)

### For Rust Developers

If you're building Rust applications or need native performance, you can use the Rust crate directly instead of the npm package.

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

**Or add to Cargo.toml:**
```toml
[dependencies]
agentic-jujutsu = "0.1"
```

**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(())
}
```

**WASM Compilation:**

The npm package uses WASM compiled from this Rust crate. If you want to build custom WASM bindings:

```bash
# Install wasm-pack
cargo install wasm-pack

# Build for different targets
wasm-pack build --target web       # Browser
wasm-pack build --target nodejs    # Node.js
wasm-pack build --target bundler   # Webpack/Vite
wasm-pack build --target deno      # Deno
```

**Why Use Rust Instead of npm?**

| Feature | npm/npx (WASM) | Rust (Native) |
|---------|---------------|---------------|
| **Setup** | `npx` instant | Cargo install |
| **Performance** | Fast (WASM) | Fastest (native) |
| **Use Case** | AI agents, scripts | Rust apps, native tools |
| **Dependencies** | Node.js required | Rust only |
| **Best For** | Quick prototyping | Production systems |

**Cargo Resources:**
- **📦 crates.io**: https://crates.io/crates/agentic-jujutsu
- **📖 Rust Docs**: https://docs.rs/agentic-jujutsu
- **🔧 Examples**: See `examples/` directory in repo

**Most users should use npm/npx** - it's easier and works great! Only use Cargo if you're already building Rust applications.
