I paste a 400 line component and ask for a change. It gives the file back but with // ... rest of your code unchanged ... in random places. When I copy it over my file, stuff is missing and the app breaks. Sometimes I don't notice for a day.
Asked 'give the full file without skipping'. It does, but then it gets cut off at the end.
Raj's approach, plus: split the 400-line component. That's also why the AI struggles; smaller files mean smaller, complete answers.
And use git (even locally): after pasting, git diff shows immediately if 80 lines disappeared. That's the part that bites you a day later.
Stop asking for full files. Ask only for what changes:
Only show the functions you change, complete, with the function name as a heading. Don't return unchanged code.
Then paste those in yourself. Smaller answers, nothing gets silently dropped.
