What it’s for
- Running coding tasks inside the IDE, with the project already indexed
- Planning before acting and following execution in real time, with the option to intervene
- Editing multiple files and adjusting tests and configuration
- Running on the command line (Junie CLI) and in GitHub Actions/GitLab CI
