The organization defines read permissions for tokens by default. You can assign specific permissions in your workflow for specific jobs, see:

https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs

That is the preferred way to do it instead of enabling write permissions by default which would also have to be enabled on organization level first.

In the long run we would like to enforce read permissions by default for every Eclipse project. Here you can see some example how you define that job level permissions:

Thank you, but I would like this way to be consistent with our other repositories like eclipse-sirius.

Ok I will update my workflows, thank you.
