Unsafe migrations fail quietly until they do not.

One unsafe migration can drop customer data.
AI agents can miss deployment context without a strict workflow.
Rollbacks are often unclear until it is too late.

What DB Preflight checks

A practical deployment safety checklist for common database migration hazards.

/DROP COLUMN / DROP TABLE
/ALTER TYPE / enum changes
/NOT NULL additions
/missing defaults
/foreign key changes
/index creation risk
/table locks
/data backfill risk
/missing rollback plan
/production connection string exposure

Sample audit preview

DB Preflight guides the agent toward concise, PR-ready findings: severity, evidence, deployment sequence, and manual verification. It reduces risk without pretending to guarantee safety.

Migration safety review

HIGH RISK
BLOCKER

New NOT NULL column has no default or backfill plan.

HIGH

Enum change may break older app versions during rolling deploy.

MEDIUM

DROP COLUMN removes recoverable user metadata after deploy.

ROLLBACK GAP

No down migration or data recovery note found.

LOCKING RISK

Constraint validation can block writes on larger tables.

Recommendation: use an expand/contract sequence, deploy nullable first, backfill in batches, verify on staging, then remove legacy fields in a later migration after app compatibility is proven.

FAQ

Is this a SaaS?

No. DB Preflight is a downloadable SKILL.md package for AI coding agents. You keep it in your local workflow or agent skill folder.

Does it connect to my database?

No. The workflow is read-only by default and reviews files, migrations, schema diffs, and deployment notes. It should not connect to production unless you explicitly request that.

Does it run migrations?

No. It is a preflight audit workflow. It must never instruct an agent to run destructive commands or automatically apply migrations.

Does it guarantee zero migration risk?

No. It is a risk-reduction and structured review tool. You are still responsible for production review, backups, staging checks, and deployment decisions.

Which agents does it work with?

It is designed for Codex, Claude Code, Cursor, OpenClaw, Gemini CLI, and other SKILL.md-compatible or prompt-workflow AI coding agents.

Can I use it in client projects?

Yes, a single-user or single-organization license allows internal use and commercial use of outputs, including client delivery work.

What happens if I lose the download link?

Contact support with your PayPal order ID. The MVP uses expiring links, and support can help verify and reset access.
