8Comprehensive guide to implementing CQRS (Command Query Responsibility Segregation) patterns.
9 
10## Use this skill when
11 
12- Separating read and write concerns
13- Scaling reads independently from writes
14- Building event-sourced systems
15- Optimizing complex query scenarios
16- Different read/write data models are needed
17- High-performance reporting is required
18 
19## Do not use this skill when
20 
21- The domain is simple and CRUD is sufficient
22- You cannot operate separate read/write models
23- Strong immediate consistency is required everywhere
24 
25## Instructions
26 
27- Identify read/write workloads and consistency needs.
28- Define command and query models with clear boundaries.
29- Implement read model projections and synchronization.
30- Validate performance, recovery, and failure modes.
31- If detailed patterns are required, open `resources/implementation-playbook.md`.
