Use when separating read and write models, optimizing query performance, or building event-sourced systems.","description":"# CQRS Implementation\n\nComprehensive guide to implementing CQRS (Command Query Responsibility Segregation) patterns.\n\n## Use this skill when\n\n- Separating read and write concerns\n- Scaling reads independently from writes\n- Building event-sourced systems\n- Optimizing complex query scenarios\n- Different read/write data models are needed\n- High-performance reporting is required\n\n## Do not use this skill when\n\n- The domain is simple and CRUD is sufficient\n- You cannot operate separate read/write models\n- Strong immediate consistency is required everywhere\n\n## Instructions\n\n- Identify read/write workloads and consistency needs.\n- Define command and query models with clear boundaries.\n- Implement read model projections and synchronization.\n- Validate performance, recovery, and failure modes.\n- If detailed patterns are required, open `resources/implementation-playbook.md`.\n\n## Resources\n\n- `resources/implementation-playbook.md` for detailed CQRS patterns and templates.\n\n## Limitations\n- Use this skill only when the task clearly matches the scope described above.\n- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.\n- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.","tags":["cqrs","implementation","antigravity","awesome","skills","sickn33","agent-skills","agentic-skills","ai-agent-skills","ai-agents","ai-coding","ai-workflows"],"capabilities":["skill","source-sickn33","skill-cqrs-implementation","topic-agent-skills","topic-agentic-skills","topic-ai-agent-skills","topic-ai-agents","topic-ai-coding","topic-ai-workflows","topic-antigravity","topic-antigravity-skills","topic-claude-code","topic-claude-code-skills","topic-codex-cli","topic-codex-skills"],"categories":["antigravity-awesome-skills"],"synonyms":[],"warnings":[],"endpointUrl":"https://skills.sh/sickn33/antigravity-awesome-skills/cqrs-implementation","protocol":"skill","transport":"skills-sh","auth":{"type":"none","details":{"cli":"npx
