CQRS Implementation

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

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.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
