SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill provides automated comparison of schema states to identify risky changes before applying migrations or after model changes, helping to mitigate potential issues.

Core Features & Use Cases

  • Schema Comparison: Compare old and new schema states.
  • Risk Assessment: Flag changes with high risk such as dropped columns, narrowed types, or new NOT NULL constraints.
  • Pre-deploy Check: Use as a pre-deployment check to ensure schema changes are safe.
  • Use Case: Before deploying a new version of a database, use this Skill to identify any schema changes that could cause issues, such as dropped columns that contain data.

Quick Start

Run the schema-diff skill on the current and proposed schema files to check for risky changes.

FAQPage Schema
How do I check for risky database schema changes before a migration?▼

Comparing two schema states identifies risky changes before database migrations. It assesses the impact of schema modifications on data integrity and system stability by parsing schema files and flagging high-risk changes like dropped columns or new NOT NULL constraints.

What database schema changes are considered high risk during a comparison?▼

High-risk database schema changes include dropped columns containing data, narrowed types, and new NOT NULL constraints. Running a pre-deployment schema comparison flags these modifications to prevent potential data loss and system instability.

How do I run a pre-deployment schema comparison for my database?▼

To run a pre-deployment schema comparison, execute the comparison logic on your current and proposed schema files. This identifies risky changes, verifying that schema modifications are safe before deploying a new database version.

Can I use schema comparison scripts without additional database dependencies?▼

Yes, you can use schema comparison scripts without additional database dependencies. The comparison logic operates by parsing schema files directly, requiring no external dependencies to assess migration risks and data integrity impacts.

What is the best way to automate database maintenance risk assessment for migrations?▼

The best way to automate database maintenance risk assessment is to run automated schema comparison checks on proposed schema files. This pre-deploy check flags risky changes, ensuring schema modifications maintain system stability before deployment.
