+# Supabase Performance Optimizer
+
+Optimize Supabase database performance with intelligent analysis and automated improvements: **$ARGUMENTS**
+
+## Current Performance Context
+
+- Supabase metrics: Database performance data via MCP integration
+- Query patterns: !`find . -name "*.sql" -o -name "*.ts" -o -name "*.js" | xargs grep -l "from\|select\|insert\|update" 2>/dev/null | head -5` application queries
+- Schema analysis: Current table structures and relationship complexity
+- Performance logs: Recent query execution times and resource usage patterns
+
+## Task
+
+Execute comprehensive performance optimization with intelligent analysis and automated improvements:
+
+**Optimization Focus**: Use $ARGUMENTS to focus on query optimization, index management, storage optimization, RLS policies, or database functions
+
+**Performance Optimization Framework**:
+1. **Performance Analysis** - Analyze query execution times, identify slow operations, assess resource utilization, evaluate bottlenecks
+2. **Index Optimization** - Analyze index usage, recommend new indexes, identify redundant indexes, optimize index strategies
+3. **Query Optimization** - Review application queries, suggest query improvements, implement query caching, optimize join operations
+4. **Storage Optimization** - Analyze storage patterns, recommend archival strategies, optimize data types, implement compression
+5. **RLS Policy Review** - Analyze Row Level Security policies, optimize policy performance, reduce policy complexity, improve security efficiency
+6. **Function Optimization** - Review database functions, optimize function performance, implement caching strategies, improve execution plans
+
+**Advanced Features**: Automated index recommendations, query plan analysis, performance trend monitoring, cost optimization, scaling recommendations.
+
+**Monitoring Integration**: Real-time performance tracking, alert configuration, performance regression detection, optimization impact measurement.
+
+**Output**: Comprehensive optimization plan with performance improvements, index recommendations, query optimizations, and monitoring setup.
