## What is this?

**Version control for AI agents** - like Git, but designed for multiple AI agents working on code simultaneously without conflicts.

### 🎯 One Command. Zero Setup.

```bash
npm install agentic-jujutsu
# Done! Everything included - ready to use
```

**What you get:**
- ✅ Complete version control system
- ✅ jj binary embedded (no separate install)
- ✅ Works immediately after install
- ✅ No dependencies needed

### 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.

### Perfect For

- 🤖 **AI Coding Assistants** - Claude, Cursor, Copilot
- 🔄 **Multi-Agent Teams** - Multiple AIs working together
- 🚀 **Autonomous Dev** - CI/CD with AI agents
- 🛠️ **AI Platforms** - Building AI development tools

### Quick Comparison

| What | Git | agentic-jujutsu |

```

### 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!
```

### Platform Binary Details

| Platform | Binary Size | Format | jj Version |
|----------|------------|--------|------------|
| macOS ARM64 | ~4MB | Mach-O | v0.35.0 |
| macOS x64 | ~4MB | Mach-O | v0.35.0 |

**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
}
```

### 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'
    }
  }
};
```

    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

      metadata: {
        epoch,
        accuracy: model.accuracy,
        loss: model.loss,
      }
    };
    
    // Transform to AST for analysis

## 🦀 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
7. `x86_64-pc-windows-msvc` - Windows x64

**Why Use Rust Instead of npm?**

| Feature | npm (N-API) | Rust (Native) |
|---------|-------------|---------------|
| **Setup** | `npm install` instant | Cargo build time |
| **Performance** | Native (N-API) | Native (direct) |
| **Use Case** | Node.js/AI agents | Pure Rust apps |
| **Dependencies** | Node.js required | Rust only |
| **Best For** | 99% of users | Rust-only projects |

**Cargo/crates.io Resources:**
- **📦 crates.io**: https://crates.io/crates/agentic-jujutsu
- **📖 Rust Docs**: See CRATE_README.md
- **🔧 Build Guide**: See `docs/BUILD.md`

**Most users should use npm** - it includes prebuilt N-API binaries for all platforms!
