Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

The Problem with Git + AI Agents

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

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 - a modern VCS designed for parallel work:

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

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:

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

// 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

🧠 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

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

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

CLI AST Usage

# 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

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

{
  "command": "jj status",
  "__ai_metadata": {
    "complexity": "low",
    "riskLevel": "low",
    "suggestedActions": []
  }
}

High Complexity Conflict

{
  "type": "Conflict",
  "__ai_metadata": {
    "complexity": "high",
    "riskLevel": "high",
    "suggestedActions": ["resolve_conflict", "abandon", "squash"]
  }
}

Medium Complexity Multi-Step

{
  "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

# Terminal 1: Start MCP server
npx agentic-jujutsu mcp-server

Step 2: Connect Your AI Agent

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

// 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

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:

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

// 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:

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

// 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:

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

    // 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):

// 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:

// config/mcp-agent.js

    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',

🗄️ AgentDB - Operation Tracking & Learning

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

Quick Start

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

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

Query Operations

// 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

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

Operation Data Structure

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

// 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

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

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`);
    }
}

Tracked Operation Types

AgentDB tracks 30+ operation types including:

Read Operations: Status, Log, Diff Write Operations: New, Describe, Edit, Abandon, Rebase, Squash, Undo Branch/Bookmark: Branch, Bookmark Remote: GitFetch, GitPush, Push, Fetch Special: Resolve, Restore, Split, Duplicate, Merge

🧠 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

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:

// 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:

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:

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:

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:

// 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

// 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

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

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

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)

🎓 Advanced Concepts

Lock-Free Architecture

Jujutsu's lock-free design enables:

  • Concurrent operations by multiple agents
  • No waiting for locks
  • Automatic conflict resolution (87% success rate)
  • Instant context switching (50-100ms)

AI-Optimized AST

The AST transformation provides:

  • Complexity scoring for operation planning
  • Risk assessment for safety checks
  • Action suggestions for agents
  • Pattern learning from history

MCP Protocol Benefits

MCP integration enables:

  • Standardized tool calling across agents
  • Resource discovery for AI systems
  • JSON-RPC 2.0 compatibility
  • Extensible architecture for custom tools

🦀 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:

cargo add agentic-jujutsu

Or add to Cargo.toml:

[dependencies]
agentic-jujutsu = "2.0"

Basic Rust Usage:

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:

# 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 |
