Expert Prompt Engineer with Context Engineering, Meta-Prompting, Chain-of-Thought, Few-Shot, Agent Design, 50+ Template Library, and A/B Testing
Expert Next.js 16 + React 19 with App Router, Server Components, Prisma 7, and Better Auth
Claude Code update watcher: changelog tracking, breaking changes detection, community pulse via Exa, plugin compatibility analysis
Expert React 19 with hooks, TanStack Router, Zustand, React Hook Form, Testing Library, shadcn/ui, and SOLID principles
A plugin ecosystem that turns Claude Code into a supervised, multi-agent development environment. Expert agents write code, hooks enforce quality in real-time, skills inject framework-specific knowledge, and intelligent cartography auto-maps plugins and projects — so Claude never guesses, never duplicates, and always follows your architecture.

Without plugins: Claude Code writes code based on its training data. It can hallucinate APIs, duplicate existing code, ignore your project structure, and produce inconsistent quality.

# Setup (hooks + API keys + MCP servers)

User prompt → Hook detects project type → Expert agent activated
→ Hook loads SOLID references → Agent reads docs via MCP
→ Hook blocks if DRY violation → Agent writes code
→ Hook checks file size → Sniper validates quality
→ Hook blocks secrets → Commit with version bump
Every step is intercepted. Claude cannot skip research, cannot duplicate code, cannot exceed file size limits, and cannot commit without security validation.
Each plugin provides an expert agent that auto-activates when it detects the framework in your project. The agent has access to official documentation via MCP servers and follows SOLID principles enforced by hooks.
