🚀 Claude Auto-Commit v0.1.4: Enhanced AI Git Commit Generation with Claude Code SDK

#claude #ai #git #productivity

Introduction

Ever struggled with writing Git commit messages?

I used to face these daily challenges:

"Can't think of the right English expression..."
"Commit message granularity is all over the place"
"Making it comply with Conventional Commits is tedious every time"
"Ending up with lazy messages like fix or update"

Especially during late-night coding sessions, I'd write commit messages like "it works now" and later wonder "what did this fix again?"

That's why I developed Claude Auto-Commit - a tool that leverages Claude AI to solve these problems once and for all.

GitHub: https://github.com/0xkaz/claude-auto-commit
Website: https://claude-auto-commit.0xkaz.com

Features & Demo

🚀 Key Features

Intelligent Message Generation: Claude AI understands code changes and generates appropriate messages
Multi-language Support: Supports 6 languages including Japanese, English, and Chinese
Safety Features: Pre-push confirmation to prevent accidental mistakes
Commit History Analysis (v0.0.5): Learns from past patterns for personalization
Smart File Grouping (v0.0.5): Logically categorizes related files
Auto-update Feature: Daily checks for the latest version
Lightweight Implementation: Fast operation with simple shell scripts

📺 Real Usage Example

# Before: My traditional commits
git commit -m "fix"
git commit -m "update user"
git commit -m "it works"  # This is embarrassing...

# After: Using Claude Auto-Commit
$ claude-auto-commit

# AI analyzes and generates messages like:
✨ Add user authentication feature with JWT tokens
- Implement login endpoint with email/password validation  
- Add JWT token generation and verification middleware
- Create protected route guards for authenticated users

# Pre-push confirmation feature
⚠️ About to push to remote repository (main branch)
Continue with push? (y/n):

The difference is remarkable!

Technical Stack

Technology Choices and Rationale

Language: Node.js (ES Modules)
- Modern JavaScript implementation
- Parallel processing for enhanced performance
- Rich ecosystem and tooling
AI: Claude Code SDK (Anthropic)
- High-quality natural language understanding/generation
- OAuth authentication for secure connections
- Exponential backoff for improved stability
Distribution: npm + GitHub Releases
- Easy execution via npx
- Automated version management
CI/CD: GitHub Actions
- Automated testing and releases

Installation & Usage

Easy Installation

# Direct execution with npm (recommended)
npx claude-auto-commit

# Or traditional installation method
curl -fsSL https://claude-auto-commit.0xkaz.com/install.sh | bash

Basic Usage

# Basic usage (OAuth authentication, auto-connect)
npx claude-auto-commit

# Japanese commit messages
npx claude-auto-commit --lang ja

# Conventional Commits format
npx claude-auto-commit --conventional

# Dry run mode (don't actually commit)
npx claude-auto-commit --dry-run

# Template system utilization (v0.1.4 new feature)
npx claude-auto-commit --template "feat: {description}"

# Show statistics
npx claude-auto-commit --summary

Configuration File

// ~/.claude-auto-commit/config.json
{
  "language": "en",
  "conventional": true,
  "templates": {
    "feature": "feat: {description}",
    "bugfix": "fix: {description}",
    "docs": "docs: {description}"
  },
  "auth": {
    "method": "oauth"
  },
  "advanced": {
    "maxDiffLines": 200,
    "timeout": 30,
    "retryCount": 3,
    "enableCache": true
  }
}

Performance & Optimization

Measured Performance Results

Average execution time: 1-2 seconds (significantly improved in v0.1.4)
Claude Code SDK communication: 0.8-1.5 seconds
Parallel processing: <0.3 seconds
Caching efficiency: 50% faster after initial run

Optimization Highlights

Parallel Processing & Caching

   // v0.1.4 parallel processing implementation
   const [diffAnalysis, historyData] = await Promise.all([
     analyzeDiff(gitDiff),
     getCachedHistory()
   ]);

Exponential Backoff

   // Improved stability with retry functionality
   const result = await retryWithBackoff(async () => {
     return await claudeCodeSDK.generateMessage(prompt);
   }, { maxRetries: 3 });

Intelligent Caching
- Persistent Claude Code SDK response caching
- Project-specific configuration caching
- Template result optimization

Real-World Impact

Development Efficiency Improvements

Results from 3 weeks of private beta testing:

Time Savings: 10 minutes saved per day (about 60 hours annually!)
History Quality: 80% improvement in readability (subjective evaluation)
Team Efficiency: 30% reduction in code review time
Stress Reduction: Almost zero hesitation during commits

User Feedback

"I can't develop without this anymore. My commit history became beautiful, making it easier to track my past work"

"I was bad at English, but now I can write professional messages with confidence"

"Our whole team adopted it, and the project's readability improved dramatically"

Architecture & Implementation

Processing Flow

graph LR
    A[Get Git diff] --> B[Analyze file changes]

Smart Change Analysis (v0.0.5)

# Smart file grouping
analyze_changes() {
    local changes=$(git diff --name-only)

    # Categorize by file type
    local frontend_files=$(echo "$changes" | grep -E "\\.(js|jsx|ts|tsx|vue|react)$")
    local backend_files=$(echo "$changes" | grep -E "\\.(py|go|java|rb|php)$")
    local test_files=$(echo "$changes" | grep -E "test|spec")

    # Analyze nature of changes
    local additions=$(git diff --numstat | awk '{sum += $1} END {print sum}')
    local deletions=$(git diff --numstat | awk '{sum += $2} END {print sum}')

    generate_context_prompt "$frontend_files" "$backend_files" "$test_files" "$additions" "$deletions"
}
