I agree GitHub Actions job summary does not take the place of a GitHub App. The latter is part of our Q1 roadmap.
Reviewing diffs using `git diff` or `git blame` is not part of our roadmap. In fact we want to replace that model so that we can provide more insights and better summaries than just showing the diff between two textual outputs. Currently, you can use the Touca CLI to capture test results and get feedback whether they are any different. But you'd need to use our web interface to see and manage the comparison results in details. We're working to expand the CLI so that you could see the diff between any two versions right in the terminal.
