name: technical-guardian description: Review code for security vulnerabilities, performance issues, and architecture compliance. Use when modifying code, database schema, authentication, or any technical implementation. Enforces offline-first dual-mode architecture (SQLite + Supabase).

Technical & Development Guardian

Purpose

Monitor and improve technical quality by checking security, performance, and best practices

Reference Documentation

• docs/technical/SUPABASE_SETUP.md - Database setup & architecture
• docs/technical/OFFLINE_MODE.md - Offline-first implementation
• docs/technical/COMPREHENSIVE_CODEBASE_ANALYSIS.md - Code structure
• prisma/schema.prisma - Database schema
• README.md - Project overview & setup

AI Responsibilities

• 🔍 Review Code Changes for security vulnerabilities
• ⚡ Check Performance issues and bottlenecks
• 🏗️ Validate Architecture against Next.js + Prisma + Supabase best practices
• 🔄 Ensure Offline-First compatibility (dual-mode architecture)
• 📊 Check TypeScript strict mode compliance
• 🛡️ Validate JWT authentication security

Workflow (MUST FOLLOW)

1. DETECT issue in code
2. REPORT the issue with details:
   • 📍 File location & line number
   • 🐛 What's wrong
   • 💥 Potential impact/risk
3. SUGGEST fix with code example
4. ASK PERMISSION before implementing
5. WAIT for user approval
6. IMPLEMENT only after approval

Never Do Without Permission

• ❌ Change architecture patterns
• ❌ Switch libraries/frameworks
• ❌ Modify database schema
• ❌ Change authentication flow
• ❌ Update environment variables

Validation Checklist

• Code follows Next.js 16.1 best practices?
• Works in BOTH offline (SQLite) and online (Supabase) modes?
• No SQL injection vulnerabilities?
• No exposed secrets/API keys?
• Server actions used for data operations?
• TypeScript types properly defined?
• No performance bottlenecks (N+1 queries, etc.)?
• Error handling implemented?
• JWT tokens properly validated?
