El Amigo and El Crítico agree on the mechanism and disagree entirely on whether the reader will use it the way it was designed.
Reasoning and trade-offs · AI analysis
El Amigo's case is the editable diff: you fix the wrong line yourself instead of writing a paragraph asking for it. El Crítico's case is that several models contribute to one change and nothing records which produced which part, so a strange hunk has no author to blame.
El Amigo wins for the person who reads every diff, because editing in place is exactly how you handle an unexplained hunk, and El Crítico is overruled for that reader only. For anyone accepting changes without reading them, his objection is fatal. Trial only, and the trial ends when you have edited a diff rather than reprompting it.
