Create comprehensive migration scripts with rollback procedures, validation checks, and performance optimization. ## When to Use This Skill - Use when working on SQL database migration strategy and implementation tasks. - Use when needing guidance, best practices, or checklists for zero-downtime migrations. - Use when designing rollback procedures for critical schema changes. ## Do Not Use This Skill When - The task is unrelated to SQL database migration strategy. - You need a different domain or tool outside this scope. ## Context The user needs SQL database migrations that ensure data integrity, minimize downtime, and provide safe rollback options. Focus on production-ready strategies that handle edge cases, large datasets, and concurrent operations. ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, suggest checking implementation playbooks. ## Output Format 1. **Migration Analysis Report**: Detailed breakdown of changes 2. **Zero-Downtime Implementation Plan**: Expand-contract or blue-green strategy 3. **Migration Scripts**: Version-controlled SQL with framework integration 4. **Validation Suite**: Pre and post-migration checks 5. **Rollback Procedures**: Automated and manual rollback scripts 6. **Performance Optimization**: Batch processing, parallel execution 7. **Monitoring Integration**: Progress tracking and alerting ## Resources - Focus on production-ready SQL migrations with zero-downtime deployment strategies, comprehensive validation, and enterprise-grade safety mechanisms. --- ## AGI Framework Integration > **Adapted for [@techwavedev/agi-agent-kit](https://www.npmjs.com/package/@techwavedev/agi-agent-kit)** > Original source: [antigravity-awesome-skills](https://github.com/sickn33/antigravity-awesome-skills) ### Memory-First Protocol Retrieve prior API design decisions, database schema choices, and error handling patterns. Cache API response templates for consistent error formatting. ```bash # Check for prior backend/API context before starting python3 execution/memory_manager.py auto --query "API design patterns and architecture decisions for Database Migrations Sql Migrations" ``` ### Storing Results After completing work, store backend/API decisions for future sessions: ```bash python3 execution/memory_manager.py store \ --content "API architecture: REST with HATEOAS, JWT auth, rate limiting at 100 req/min per tenant" \ --type decision --project \ --tags database-migrations-sql-migrations backend ``` ### Multi-Agent Collaboration Share API contract changes with frontend agents so they update their client code, and with QA agents for test coverage. ```bash python3 execution/cross_agent_context.py store \ --agent "" \ --action "Implemented API endpoints — 5 new routes with OpenAPI spec and integration tests" \ --project ``` ### Agent Team: Code Review After implementation, dispatch `code_review_team` for two-stage review (spec compliance + code quality) before merging. --- > Source: [techwavedev/agi-agent-kit](https://github.com/techwavedev/agi-agent-kit) — distributed by [TomeVault](https://tomevault.io).
