How does it handle frontend technologies like Tailwind?

It aligns with your current setup. If you use Tailwind, it continues using Tailwind; if you use vanilla CSS, it follows that convention.

Does it support RSpec or only Minitest?

The skill is pragmatic; if your team uses RSpec, it will write RSpec tests rather than suggesting a switch to Minitest.

Does this skill work with existing Rails projects?

Yes. While it follows DHH's ideal patterns, it is designed to respect your existing codebase's history and will not force changes to your current testing frameworks or CSS libraries.

Can this skill help with Rails architectural decisions?

Yes, it provides guidance based on the 'Majestic Monolith' philosophy, helping you make decisions that simplify your stack and improve maintainability.
