interactive

The step-level interactive field attaches your terminal's stdin to a type: shell step, so the command can read input from you while it runs.

steps:
  - name: psql
    type: shell
    command: psql "$DATABASE_URL"
    interactive: true
    tty: true

While an interactive step runs, Atmos lets the child process handle Ctrl-C. Combine interactive: true with tty: true for full terminal sessions.
