The request names GitHub Actions on Ubuntu runners, so GitHub comes first; its source shows an AI-powered developer platform with workflow-related actions such as efficiency audits 212, but none of the indexed actions clearly frees disk space on runners. Ubuntu 1 is the runner operating system itself, and no product here is confirmed to do the disk-cleanup job, so a clarifying question is raised.
A question back: Do you want a GitHub Actions step or action that removes unused packages and caches on Ubuntu runners, and should it work on the default GitHub-hosted image?
