Run local command with Ansible and share variable in the remote context - ansible

Question

I have the following logic that I would like to implement with Ansible:
Before to update some operating system packages, I want to check some other remote dependencies, which involve querying some endpoints and decide if the next version is good or not.
The script new_version_available returns 0 if there is something new and 1 if there isn't something new.
To avoid install unnecessary packages in production, or open unnecessary ports in my firewall in the DMZ, I would like to run this script locally in my host and if it succeeds, then we run the next task remotely.
tasks:
- name: Check if there is new version available
command: "{{playbook_dir}}/new_version_available"
delegate_to: 127.0.0.1
register: new_version_available
ignore_errors: False
- name: Install our package
command:
cmd: '/usr/bin/our_installer update'
warn: False
when: new_version_available is succeeded
Which gives me the following error:
fatal: [localhost -> 127.0.0.1]: FAILED! => {"changed": false, "cmd": "/home/foo/ansible-deploy-bar/new_version_available", "msg": "[Errno 2] No such file or directory", "rc": 2}
That means that my command cannot be found, however my script exists and i have permission to access it.
My Development environment where I'm testing the playbook, is running in a virtual machine, via NAT, where forward the Guest port 22 to my host 2222, so if i want to login in my VM I do ssh root#localhost -p 2222. My inventory looks like:
foo:
hosts:
localhost:2222
My Question is:
What would be the Ansible way to achieve what I want, i.e run some command locally and pass the results to a register and use it as condition in a task? Run the command and pass the result as environment variable to Ansible?
I'm using this documentation as support https://docs.ansible.com/ansible/latest/user_guide/playbooks_delegation.html
