+
+# SQL Optimization Patterns
+
+Transform slow database queries into lightning-fast operations through systematic optimization, proper indexing, and query plan analysis.
+
+## Use this skill when
+
+- Debugging slow-running queries
+- Designing performant database schemas
+- Optimizing application response times
+- Reducing database load and costs
+- Improving scalability for growing datasets
+- Analyzing EXPLAIN query plans
+- Implementing efficient indexes
+- Resolving N+1 query problems
+
+## Do not use this skill when
+
+- The task is unrelated to sql optimization patterns
+- You need a different domain or tool outside this scope
+
+## Instructions
+
+- Clarify goals, constraints, and required inputs.
+- Apply relevant best practices and validate outcomes.
+- Provide actionable steps and verification.
+- If detailed examples are required, open `resources/implementation-playbook.md`.
