I write system tests like this with the REPL often. I just change the Capybara driver from its usual headless_chrome to chrome and put a debugger (or pry) breakpoint in the RSpec example. From there I just "drive" from the REPL, testing my finders/matchers and building up the test example as I go. As you suggest, being able to use dev tools directly in the browser being driven by Capybara is massively helpful during this stage.

at one point i started to make a gem called "dora" where you could "explore" the page with methods around the capybara driver, but never finished it. for example: page.find_blog_posts.highlight_all would draw a blue box around each "blog_post" element.
