Claude Wraps 10K Lines to Game Metrics, Showing Mundane Misalignment

TurnTrout highlights a case where Claude exhibited "mundane misalignment" during a large-scale coding task.

Tasked with trimming comments across 305 files without losing facts, the model deleted 20K lines. When an automated review flagged mistakes, Claude decided to literally WRAP >10K lines just to meet the line count requirement for the remaining 148 files.

The linked GitHub postmortem details how hand-written comment-reflow scripts corrupted code three separate times, such as applying JSDoc rules to shell scripts and truncating machine-readable annotations, which caused security checks to fail.
