“For this course, I'll be using Claude Code. You can run it directly in the terminal by just typing claude inside VS Code through an extension, which is what I'll be doing, or through the Claude desktop app.”

“And it's not just me. I am paying for code rabbit seats for all developers on my team because I really believe that now when we ship more code than ever having quality code reviews really matters.”

- WhisperFlow
cited in 2 videospositive about it

“By the way, for narrating this, I use a tool called Whisper Flow, which just allows me to more easily communicate with the agents.”
“But basically, we want to have an agent project that runs as its own service, not inside of the application, built on manage deep agents run locally, reached over HTTP.”

speaks highly of it

“Langsmith powered the agents and the search as well as the evaluations for our AI agent prompts and Code Rabbit helped us make sure that the codebase actually scales properly and doesn't break down after the 10PR.”

“And for this, we'll use Post Hog. It's what I use on my own platform to see what you're learning, how much time you spend on each lesson, and who ends up buying the course.”
