    Sample input

    User request: "I need to split the large orders table by moving order items into a separate table."

    Sample output

    Generated Output (excerpt):

    Database Change Plan

    Change Summary Split the monolithic orders table by extracting order_items into its own table for better normalization and query performance.

    Risk Level High — Large table (12M rows), many existing queries, financial data.

    Current State Analysis

    • Tables affected: orders (12M rows)
    • Consumers impacted: Order service, reporting jobs, customer portal, analytics pipeline
    • Risks: Long-running migration, potential locking, complex backfill

    Target Schema Design

    • New order_items table with foreign key to orders
    • Move product_id, quantity, unit_price into the new table
    • Add indexes on order_id and product_id

    Migration Strategy | Step | Type | Operation | Risk | Rollback Plan | Verification Method | |------|------------|----------------------------------------|----------|------------------------|------------------------------| | 1 | Additive | Create order_items table + indexes | Low | Drop table | Schema validation | | 2 | Backfill | Batch copy data (10k rows at a time) | High | Truncate + re-run | Row count + checksum | | 3 | Dual-write | Modify app to write to both | High | Revert application code| Compare row counts | | 4 | Contract | Drop old columns after 2 weeks | Critical | Full DB restore | Confirm no queries reference old columns |

    Data Backfill / Transformation Plan Use batched migration script with 2-second pauses. Run during low-traffic window (02:00–04:00 UTC).

    Verification Checklist

    • [ ] Row counts match between old and new structures
    • [ ] All reporting queries updated and tested
    • [ ] Performance tests show improvement on order detail queries
    • [ ] Rollback procedure tested in staging

    About This Skill

    Professional Database Evolution Strategy

    Database schema changes are high-stakes operations where a single mistake can lead to data loss or system downtime. This skill provides a disciplined, safety-first methodology for designing database architectures and executing migrations with production-grade rigor.

    What it does

    It transforms your AI agent into a senior database engineer. Instead of generating simple SQL scripts, it follows a multi-phase engineering process:

    • Impact Analysis: Identifies all affected consumers, from application services to analytics pipelines.
    • Safety Design: Architectures "Expand/Contract" or "Dual-Write" patterns to ensure zero-downtime deployments.
    • Rollback Planning: Mandates explicit, tested recovery steps for every destructive operation.
    • Performance Guardrails: Plans batched backfills and index optimizations to prevent table locking on large datasets.

    Why use this skill

    Standard AI prompts often overlook the complexities of production environments. This skill enforces professional standards like row-count verification, checksums, and staging-to-production parity. It is ideal for developers managing PostgreSQL, MySQL, or SQL Server environments where data integrity is non-negotiable.

    Output

    The skill produces a comprehensive Database Change Plan, including risk assessments, step-by-step migration tables (Additive vs. Contract), and specific verification queries to run after deployment.

    Use Cases

    • Execute zero-downtime migrations for high-traffic production databases.
    • Design future-proof schemas with optimized indexing and normalization.
    • Generate comprehensive rollback plans and verification scripts for SQL changes.
    • Audit application code to identify all consumers impacted by a schema change.

    This skill carries high responsibility. While it has write access for creating migrations and models, any destructive operation (DROP, destructive ALTER, large-scale data deletion) must be explicitly approved by the user after reviewing the rollback plan.This skill carries high responsibility.
