Plan, track and check one change at a time
Plan one change
Pick one outcome, such as “People can reset their password”. Write down what should happen and how you will check it. Leave unrelated ideas for later.
Keep the record with the task
Give the task and the expected result to whoever does the work, a teammate or Claude. Keep what changed, the links and the check results with that task.
Check before people use it
Try the new behaviour, then the existing behaviour it could affect. Write down what you tested and what is still open.
