A concrete starting point
Visit every coordinate of a rectangular grid in a clockwise spiral starting at the top left. Check zero dimensions and single rows or columns, rejecting dimensions outside zero through 100 and proving each coordinate appears once.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
