    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.

    What you get

    Rename or remove columns using expand-contract workflowsAdd non-null constraints with safe backfills for existing dataIdentify deployment-breaking risks in proposed SQL migrationsMaintain compatibility between old and new application versions
