    Example session with this skill installed

    I need to rename the user_email column to email in my Postgres database without any downtime during the deployment.

    • Read your context and instructions
    • Compiled the make database changes

    I have analyzed your schema. To avoid downtime, I created a three-stage plan:

    1. Add new 'email' column (nullable).
    2. Update models for dual-writing to both fields.
    3. Added a resumable backfill script. See the generated migration files in /migrations.

    Connects securely to your tools. The creator never sees your data.

    About this skill

    Safely prepare database schema changes for live apps without breaking existing code.

    This skill detects risky migrations, replaces destructive changes with expand-contract steps, creates resumable backfills, preserves compatibility, and checks rollout order.

    • Detect deployment-breaking migrations
    • Plan safe schema changes
    • Create resumable backfills
    • Preserve old and new app compatibility
    • Validate rollback and rollout order

    Ideal for SaaS apps, APIs, and frequently deployed systems.

    What's inside

    Frequently Asked Questions

    It uses an expand-contract workflow: adding new fields, dual-writing data, backfilling, and then removing old fields in separate stages.

    Yes, it detects risky migrations like dropping columns or adding non-null constraints and suggests safer alternatives.

    The skill focuses on planning and generating migration files. It does not apply changes directly to production databases.

    It works with most major ORMs and SQL dialects by inspecting your existing codebase and migration history.
