You're getting help designing PostgreSQL schemas through structured prompts. This comes from davila7's template collection, which has a solid 27.7K stars and 233 installs so far. There's no SKILL.md in the repo, so you're working with whatever prompt patterns they've set up for table design, relationships, indexes, and constraints. Useful when you're starting a new project or refactoring an existing schema and want Claude to guide you through normalization, data types, and foreign key decisions. It won't replace knowing Postgres, but it'll save you from forgetting the basics or making obvious mistakes with indexes.
