Cursor AI Beyond Prompting

Cursor AI went from a promising code editor to a sixty billion dollar acquisition target for SpaceX in under two years. This field guide covers both the headline story and the daily reality of using it: what Cursor actually is and how its four modes differ, how to set up project rules that stop it from guessing wrong, why it loses track of large projects and the exact recovery sequence to fix it, a disciplined staged workflow for Composer and Agent mode, a full enterprise network troubleshooting decision tree, and a plain-language breakdown of the disclosed GhostApproval security vulnerability (CVE-2026-50549) along with what SpaceX's acquisition of Anysphere actually means. Every claim is sourced and dated, verified through July 2026.
