Vitess safety review

Purpose

Recommend best practices for a PlanetScale Vitess database. Focus on production safety, deployability, observability, and agent-safe automation. Do not apply any changes.

Primary safety features to evaluate

Safe migrations

Check whether safe migrations are enabled on production and staging branches.

Recommend enabling safe migrations when:

• The branch receives production traffic.
• The team runs DDL outside deploy requests.
• There is no protected branch workflow.
• The application is expected to evolve schema frequently.
