Notes

• In --yes mode Scafix enables Tailwind, tRPC, and Prisma, but leaves NextAuth disabled.
• Scafix runs create-t3-app with install and git initialization disabled, then installs dependencies with the package manager you selected.

Shared flow reminder

• Shared flags such as --name, --directory, --package-manager, --git, and --debug apply here as well.
• If required values are omitted and a TTY is available, Scafix prompts for them before calling the stack adapter.
• See CLI Reference for the shared command surface used by scafix.
