Process Overview

• Include the devise gem in your Gemfile

  gem 'devise'

• Install the gem

  bundle install

• Generate Devise files (e.g., the users model)

  rails generate devise:install
  rails generate devise User

• Review the generated migration file and then run the migration

  rails db:migrate

• Adjust the sign‑out method in config/initializers/devise.rb

  # Change the default sign out method
  config.sign_out_via = :get

• Start the Rails server and verify that the authentication routes work

  • Sign‑up page: http://localhost:3000/users/sign_up
  • Sign‑in page: http://localhost:3000/users/sign_in

• The initial setup succeeded.

• Continued development using Claude’s code window.

  • Noted high token consumption because Claude re‑read the entire file on each change.

• Asked Claude for a recommended next step (building a habit route) and leveraged First Draft Study Buddy to scaffold the code.

• Revised plan:

  1. Write as much code as possible with Study Buddy.
  2. Manually implement the core RCAV (Read‑Create‑Update‑Validate) functionality.

• When Claude credits become available again, use Claude to troubleshoot remaining bugs.
