What problem does it solve? Schemas often ship without row-level audit metadata, so teams cannot answer who created or last modified a record without replaying request logs. This Skill checks new and existing tables for the standard audit column pattern and distinguishes mutable domain rows from immutable event rows. ## Core Features & Use Cases - Schema auditing: Classifies every model as a mutable domain row or immutable event/log row, then reports gaps in createdAt, updatedAt, createdBy, and updatedBy as a structured table. - New table guidance: Applies the standard five-column pattern when creating models in Prisma, SQL, or any ORM, with correct nullability and Prisma directives like @updatedAt. - Soft-delete judgment: Advises when deletedAt is a real product requirement versus cargo-culted, avoiding permanent WHERE deletedAt IS NULL filters. - Use Case: Before adding a new Orders table in a Prisma schema, use this Skill to confirm it needs createdAt/updatedAt plus nullable createdBy/updatedBy actor FKs, while a webhook-events table gets createdAt only. ## Quick Start Review my Prisma schema for missing audit columns and tell me which tables need createdAt, updatedAt, createdBy, or updatedBy.
