What is this?

Quantum-ready, self-learning version control for AI agents - like Git, but designed for multiple AI agents working on code simultaneously without conflicts, with built-in intelligence that learns from experience and quantum-resistant security for the future.

$3

``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

$3

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
`

$3

Built on Jujutsu - 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.

🧠 AST Capabilities (AI Agents)

$3

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

$3

- 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

$3

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

$3

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

$3

`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"
}
}
`

$3

`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);
`

$3

#### 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

$3

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

$3

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
`

$3

#### 🔍 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);
}
}
}
`

$3

#### ⚙️ 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
}

`

$3

`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);
`

$3

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);
}
`

$3

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'
}
}
};

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

$3

`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);
`

$3

#### 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);

🧠 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.

$3

`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});
`

$3

#### 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

$3

#### 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..."
`
