-If you are working inside the Paperclip repo, `./companies.sh` is a thin wrapper around `paperclipai company import`. It accepts the same source-first form and still supports legacy `--from <path-or-url>` compatibility:
-
-```sh
-./companies.sh org/repo/companies/acme --dry-run
-./companies.sh --from ./my-export --target existing --company-id abc123
-```
