zjucc2005/slime_crm — reverse-engineered prompt

Build me a simple custom CRM web app in Ruby on Rails 6, using Ruby 2.6. I want it to feel like a practical internal tool for a small team, not a marketing site.

The main goal is to help staff keep track of customers, contacts, conversations, status, notes, and next actions. Make the screens clean and easy to understand, with basic pages to add, edit, view, search, and organize CRM records. Include sensible sample data so I can see how it works right away.

Please set up the database, routes, models, controllers, views, and any basic styling needed. Keep it straightforward and maintainable, since this is a customized CRM that may grow later. Add clear setup instructions so someone can clone it, install dependencies, create the database, run migrations, and start the app locally.

If you need details about Rails 6 behavior, look up the current docs online.
