@00rakhul: Comment "LEAK" and I will send you the repo. Someone collected the actual system prompts behind Claude Code, Cursor, Devin and Lovable, and put them in one public repo. Not summaries of them. The files. Claude Code opens with "You are an interactive CLI tool that helps users with software engineering tasks." Devin's opens with "You are Devin, a software engineer using a real computer operating system." Cursor's tells it that it operates in Cursor and names the model it runs on. Reading them is a fast way to stop guessing at structure, because you look at what shipped. Then you copy that structure into your own prompts and skills. Two things worth knowing before you go in. These are snapshots of specific versions, not whatever the tools are running today. And the repo publishes them; it does not claim the vendors handed them over. #systemprompts #claudecode #cursor #promptengineering #aitools
