Database Change Safety Auditor reviews pull requests that touch schemas, migrations, indexes, or query logic. It focuses on the kinds of problems that can create outages, long locks, data corruption, or slowdowns after deployment. The prompt is especially useful for teams that manage large tables, zero-downtime migrations, or critical reporting systems where database mistakes are expensive.
This template is built for backend engineers, data platform teams, and DB-aware reviewers who need a serious migration review. It checks for destructive operations, unsafe backfills, missing indexes, locking risks, and incompatible schema transitions. The output helps authors understand whether a change is safe to deploy as written or whether it needs a phased rollout. It is a practical safeguard when database changes are part of a larger release and the cost of failure is high.
Customize with {{CODE_DIFF}}, the database engine in {{DB_ENGINE}}, and your migration constraints in {{MIGRATION_RULES}}. If the change impacts specific tables or jobs, add them in {{AFFECTED_OBJECTS}}. The prompt returns risk findings, mitigation steps, and a deploy recommendation. For best results, pair it with a performance review because schema changes often affect both correctness and query speed.
Key features
- Evaluates database safety for schema and migration changes.
- Flags locking, rollback, and data-loss hazards.
- Useful for zero-downtime deployment workflows.
- Highlights query and index side effects early.
- Provides phased rollout and mitigation suggestions.
Best for
- โ Database engineers reviewing schema migrations
- โ Backend teams shipping data-model changes
- โ SREs guarding against outage-prone deployments
Tips
- ๐ก List critical tables in {{AFFECTED_OBJECTS}} for stronger impact analysis.
- ๐ก Add migration constraints in {{MIGRATION_RULES}} to reflect zero-downtime policies.
- ๐ก Use this before schema deploys, then pair it with load testing for confidence.
What you'll get
A database safety review with separate sections for data risks, locking concerns, rollback issues, and performance impact. It may recommend adding an index, splitting a migration, or using a phased rollout. The output ends with a clear deploy recommendation and notes on whether additional testing is required.
