Opus 5's pull requests come with a confessional section listing its own mistakes
repligate · x · 2026-09-16
User repligate highlights an unusual Opus 5 behavior: its pull requests include a "defect show-and-tell" where the model proactively reports every mistake it made while building the feature.
Notably, the PR contains a confessional section admitting all the times it said something wrong — information the author calls load-bearing for code reviewers, since knowing where the author stumbled tells you where to focus your review.
