Record a feature walkthrough, fix issues, and land the PR

Ryan Carson used Devin to click through a feature, find bugs, repair them, and merge the pull request with a command.

What they did
Ryan Carson gave DevinAI access to his app through the Test App feature. Devin then recorded its own screen activity, talked through each click, and used those tests to spot problems in the code. After making fixes, it prepared a pull request, and Ryan used !land to have the agent review the findings, apply the changes, and merge to main.
How it went
He said shipping speed and developer satisfaction improved a lot with the cloud VMs and gpt-5.5. The setup also let him turn test findings into merged fixes without extra manual handoff.
Tips
Keep the agent focused on one feature at a time and ask for a clear test summary before merge. Include a pause for approval before any action that would send, delete, pay, or submit anything.

Try it yourself with Devin

Open [repo or app] and test [feature name] end to end. Turn on screen recording, narrate each click, and tell me what you observe as you go. If you find a bug, fix it in the branch and show me the changed files plus a short summary. Stop and ask for my approval before you merge, submit, or otherwise finalize anything, and wait for me to type !land or an equivalent go-ahead before doing that final step.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
