A concrete starting point
Split pipe-delimited fields with backslash escapes for pipes and backslashes. Preserve empty fields and reject unknown escapes or a trailing backslash before returning any result.
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.
