Developer jarrodwatts had Opus 5.5 set up his own Linux box as a GitHub Actions runner for private repos in 10 minutes, replacing GitHub-hosted runners. Result: saving a few hundred dollars a month with much faster runs — pnpm install dropped from 24-31s to 2-3s (10x), test runs are 4.9x faster, builds 4.8x, with lint/typecheck between 2.5-3.2x.
