What problem does it solve? When you fix only the exact spot a reviewer pointed out, the same class of mistake keeps coming back. This Skill turns every review comment or self-detected failure into a learning loop: classify why the issue escaped self-review, sweep the whole diff for similar problems, embed the new viewpoint into review criteria or hooks, and record the lesson. ## Core Features & Use Cases - Feedback Classification: Categorizes each comment as a criteria gap, missing review lens, skipped review, or detection miss, so the root cause is explicit. - Horizontal Sweep: Searches the entire diff and surrounding code with Grep/Read for the same class of problem instead of fixing one location. - Prevention Embedding: Adds the new viewpoint to diff-review lens criteria, hooks, tests, lint, or PR templates, and appends a one-line entry to tasks/lessons.md. - Use Case: After a reviewer flags a missing null check, use this Skill to find every similar unchecked call in the diff, add the pattern to the review lens criteria, and log the lesson so it never recurs. ## Quick Start Use the review-feedback skill to handle this review comment and make sure the same kind of issue is caught everywhere and prevented next time.
