| # To workaroud https://github.com/actions/first-interaction/issues/10 in a secure way, | |
| # we take the following steps to generate and comment a performance benchmark result: | |
| # 1. first "performance tracking" workflow will generate the benchmark results in an unprivileged environment triggered on `pull_request` event | |
| # 2. then this "performance tracking (comment)" workflow will show the result to us as a PR comment in a privileged environment | |
| # Note that this workflow can only be modifed by getting checked-in to the default branch | |
| # and thus is secure even though this workflow is granted with write permissions, etc. | |
