+
+# CQRS Implementation
+
+Comprehensive guide to implementing CQRS (Command Query Responsibility Segregation) patterns.
+
+## Use this skill when
+
+- Separating read and write concerns
+- Scaling reads independently from writes
+- Building event-sourced systems
+- Optimizing complex query scenarios
+- Different read/write data models are needed
+- High-performance reporting is required
+
+## Do not use this skill when
+
+- The domain is simple and CRUD is sufficient
+- You cannot operate separate read/write models
+- Strong immediate consistency is required everywhere
+
+## Instructions
+
+- Identify read/write workloads and consistency needs.
+- Define command and query models with clear boundaries.
+- Implement read model projections and synchronization.
+- Validate performance, recovery, and failure modes.
+- If detailed patterns are required, open `resources/implementation-playbook.md`.
+
+## Resources
+
+- `resources/implementation-playbook.md` for detailed CQRS patterns and templates.
