This is great, it means you can set up complex concrete rules about commands CC is allowed to run (and with what arguments), rather than trying to coax these via CLAUDE.md.

E.g. you can allow

    docker compose exec django python manage.py test
but prevent

    docker compose exec django python manage.py makemigrations

You can already do this in .Claude/settings.json

That's limited to simple string matching with `*` so it can't handle anything complex.
