Claude Code Infrastructure Showcase

A curated reference library of production-tested Claude Code infrastructure.

Born from 6 months of real-world use managing a complex TypeScript microservices project, this showcase provides the patterns and systems that solved the "skills don't activate automatically" problem and scaled Claude Code for enterprise development.

This is NOT a working application - it's a reference library. Copy what you need into your own projects.

What's Inside

Production-tested infrastructure for:

• ✅ Auto-activating skills via hooks
• ✅ Modular skill pattern (500-line rule with progressive disclosure)
• ✅ Specialized agents for complex tasks
• ✅ Dev docs system that survives context resets
• ✅ Comprehensive examples using generic blog domain

Time investment to build: 6 months of iteration Time to integrate into your project: 15-30 minutes

Quick Start - Pick Your Path

🤖 Using Claude Code to Integrate?

Claude: Read CLAUDE_INTEGRATION_GUIDE.md for step-by-step integration instructions tailored for AI-assisted setup.

🎯 I want skill auto-activation

The breakthrough feature: Skills that actually activate when you need them.

What you need:

1. The skill-activation hooks (2 files)
2. A skill or two relevant to your work
3. 15 minutes

👉 Setup Guide: .claude/hooks/README.md

📚 I want to add ONE skill

Browse the skills catalog and copy what you need.

Available:

• backend-dev-guidelines - Node.js/Express/TypeScript patterns
• frontend-dev-guidelines - React/TypeScript/MUI v7 patterns
• skill-developer - Meta-skill for creating skills
• route-tester - Test authenticated API routes
• error-tracking - Sentry integration patterns

👉 Skills Guide: .claude/skills/README.md

🤖 I want specialized agents

10 production-tested agents for complex tasks:

• Code architecture review
• Refactoring assistance
• Documentation generation
• Error debugging
• And more...

What Makes This Different?

The Auto-Activation Breakthrough

Problem: Claude Code skills just sit there. You have to remember to use them.

Solution: UserPromptSubmit hook that:

• Analyzes your prompts
• Checks file context
• Automatically suggests relevant skills
• Works via skill-rules.json configuration

Result: Skills activate when you need them, not when you remember them.

Production-Tested Patterns

These aren't theoretical examples - they're extracted from:

• ✅ 6 microservices in production
• ✅ 50,000+ lines of TypeScript
• ✅ React frontend with complex data grids
• ✅ Sophisticated workflow engine
• ✅ 6 months of daily Claude Code use

The patterns work because they solved real problems.

Modular Skills (500-Line Rule)

Large skills hit context limits. The solution:

skill-name/
  SKILL.md                  # <500 lines, high-level guide
  resources/
    topic-1.md              # <500 lines each
    topic-2.md
    topic-3.md

Progressive disclosure: Claude loads main skill first, loads resources only when needed.
