🚀 Better Code with Claude: 4 AI-Powered Plugins for Code Quality

I'm excited to announce better-code (v0.1.0) - a curated collection of Claude Code plugins designed to enforce code quality practices, TDD workflows, performance analysis, and documentation standards.

Why I Built This

As developers, we often struggle with:

  • 📝 Enforcing TDD discipline across teams
  • 🐢 Missing performance bottlenecks until production
  • 📚 Outdated or missing documentation
  • 🎯 Maintaining consistent code quality

I built better-code to solve these problems using Claude Code's plugin system.

What's Inside? 📦

🧪 tdd-dev (v0.2.1)

Enforce Red→Green→Refactor TDD Cycles

Tired of tests being an afterthought? This plugin enforces writing tests before implementation.

Features:

  • Multiple strictness levels: strict, standard, relaxed
  • Supports features, bugs, and refactoring modes
  • Real-time feedback on TDD compliance 
/tdd-dev:start          # Enable TDD mode
/tdd-dev:feature "add auth"  # Write feature with TDD
/tdd-dev:bug "fix #123"      # Fix bug with regression test first

⚡ n1-optimizer (v0.1.3)

Detect N+1 Queries & Performance Issues

4 parallel agents analyze your codebase across different layers:

What it detects:

  • 🗄️ Database: N+1 queries, missing indexes, unbatched writes
  • 🔧 Backend: O(n²) algorithms, blocking I/O, memory issues
  • 🎨 Frontend: Re-render loops, large bundles, missing memoization
  • 🔗 API: Over-fetching, missing pagination, chatty endpoints

Catches performance issues before they hit production!

/n1-optimizer:analyze
Enter fullscreen mode Exit fullscreen mode

Example Output:

Analysis Complete

Database Layer: 3 issues found
HIGH: N+1 query in UserService.getOrders()

Backend Layer: 1 issue found
MEDIUM: Sequential awaits could be parallelized

Frontend Layer: 2 issues found
HIGH: Missing React.memo on ExpensiveList

API Layer: 1 issue found
MEDIUM: Missing pagination on /api/products
Enter fullscreen mode Exit fullscreen mode

📚 readme-writer (v0.1.0)

Generate Professional READMEs

Follows PRD-README v1 standard with automated scoring (0-10):

/readme-writer:generate   # Generate README from codebase analysis
/readme-writer:audit      # Score existing README (0-10)
Enter fullscreen mode Exit fullscreen mode

Audit Score: 7/10 ✓ Test 1: What is it? - PASS ✓ Test 2: Is it maintained? - PASS ✗ Test 3: Quick start works

📖 doc-master (v0.2.1)

9 Specialized Documentation Agents

Diátaxis-structured documentation covering:

/doc-master:setup       # Choose framework (Diátaxis/Traditional/Custom)
/doc-master:generate "API"  # Generate API documentation
/doc-master:audit       # Audit existing docs
/doc-master:plan        # Create documentation plan
Enter fullscreen mode Exit fullscreen mode

Agents include:

  • api-docs: REST/GraphQL endpoints, schemas
  • backend-docs: Services, data flows, deployment
  • frontend-docs: Components, state management
  • database-docs: Schema, migrations, ER diagrams
  • architecture-docs: System design, ADRs
  • test-docs: Test strategy, coverage
  • user-guide-docs: Tutorials, help articles
  • compliance-docs: Security, audit, regulatory
  • mobile-docs: iOS/Android, app stores

Quick Start ⚡ 

# 1. Add the marketplace
/plugin marketplace add hculap/better-code

# 2. Install your first plugin
/plugin install tdd-dev

# 3. Use it!
/tdd-dev:start
Enter fullscreen mode Exit fullscreen mode

That's it! You're now enforcing TDD in your workflow.

Real-World Impact
