The test runs, the merge waits for him
Ryan Carson uses Devin to test a feature, record the screen and fix bugs it finds. When he thinks the PR is ready, he types land, and it merges to main. Interface work that needs close control he does locally with Codex.

What was done
On 25 April 2026 Ryan Carson writes that he uses Devin when he is going to ship code. Test App records the screen and narrates while it clicks through the feature. It finds bugs from the test. It fixes them. When the PR is ready to ship, he types the command land. It merges to main, after reviewing the findings and fixing them. He writes that he only codes locally when the feature is heavy on the interface and needs close control. For that he uses Codex with a browser. The profile says Connecticut, USA.
How it went
He describes land merging to main after review. The post does not name the product. It does not name a bug the test found.
Worth knowing
The post does not say he read the diff before land. It does not say how often the test found a bug.
How to do it
- Let the agent test the feature, record what it clicks, and list the bugs.
- Read the diff. Say which bugs it may fix.
- Do not merge to main and do not publish until you say yes.
Try it with Valgfri agent
Test [feature] in [repo]. Record what you click, and list the bugs. Fix only what I have approved. Do not merge to main and do not publish until I say yes.
Replace text in brackets with your own.
Done when. The diff has been read, and nothing was merged to main before you said yes.
Safety rule. No merge to main and no publishing until you have said yes.
