| # This workflow monitors any run completed on the GitHub Bot workflow and | |
| # checks if the event that triggered it is limited to read-only permissions | |
| # (e.g 'pull_request_review' on a pull request opened from a fork). | |
| # In this case, it reruns the GitHub Bot workflow using a 'workflow_dispatch' | |
| # event, thereby allowing it to run with write permissions. | |
| # | |
| # Complete flow: | |
| # 'pull_request_review' from fork on bot.yml (read-only) -> 'workflow_run' on bot-proxy.yml (write) -> 'workflow_dispatch' on bot.yml (write) | |
