Technology Explorations in Data & AI

Emil shows how to let his Cursor AI access and manipulate multiple projects at the same time.
He does this by leveraging the Cursor Workspace feature, which enables you to link multiple repositories together. His demo shows how to increase application resources, which also needs a Terraform change in a second project. Along the way, we discover how important human involvement still is...
You'll learn how to:
  • Set up Cursor workspaces with multiple projects
  • Let your agent access and manipulate multiple codebases
  • Leverage best practices from previous projects
  • Be mindful that human involvement is still important
