Create Safe Backend Migrations
Database schema changes can break deployments when migrations lack rollback plans or compatibility checks. This skill guides Claude, Codex, and Claude Code toward focused migrations.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "backend-migrations" from https://skillstore.io/skills/devanb-backend-migrations.md and its manifest at https://skillstore.io/api/skills/devanb-backend-migrations/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "backend-migrations". Add a nullable customer reference to invoices with a rollback plan.
Expected outcome:
A migration plan with a clear file name, forward change, rollback behavior, and compatibility notes for older application code.
Using "backend-migrations". Review a migration that renames a column used by production services.
Expected outcome:
A risk review that recommends staged compatibility, temporary dual writes, rollback limits, and deployment order.
Using "backend-migrations". Add an index to a high-volume activity table.
Expected outcome:
A production-focused checklist covering index creation strategy, locking risk, monitoring, and rollback expectations.
Security Audit
SafeThe inline backticks on SKILL.md line 12 are markdown formatting, not shell execution. The parent-directory documentation link on line 28 is a confirmed concern because it points outside the packaged skill content.

Plan a New Schema Change
Create a focused migration with clear naming, reversible steps, and deployment considerations.
Review a Risky Migration
Check an existing migration for rollback gaps, large-table index risks, and backwards compatibility concerns.
Separate Data and Schema Work
Design safer release steps when schema changes and record updates should not run together.
Try These Prompts
Create a reversible backend migration for this schema change: [describe the table, columns, and constraints].
Plan a migration to add this index on a large table: [table and columns]. Include deployment risks and rollback steps.
Review this migration plan for reversibility, naming, backwards compatibility, and zero-downtime concerns: [paste summary].
Design a safe migration sequence for this feature: [describe schema change, data migration, and application rollout].
Best Practices
- Keep each migration focused on one logical schema change.
- Write a rollback path before treating the migration as complete.
- Plan large-table indexes and incompatible changes as staged deployments.
Avoid
- Do not mix broad schema refactors with unrelated data updates.
- Do not edit deployed migrations without understanding downstream environments.
- Do not assume a column rename is safe for running application code.
