fetch-diff

Quick Review

A well-structured skill for fetching and formatting PR diffs with line numbers. The description and usage are clear enough for invocation, and the output format is well-documented. However, the skill provides moderate novelty since fetching diffs via gh CLI or API is straightforward, though the filtering and line numbering add some value. Task knowledge is adequate but could benefit from more details on filtering logic (what counts as auto-generated?) and error handling scenarios. The structure is clean and appropriate for a single-function skill. Overall, a solid utility skill that reduces some friction in code review workflows but doesn't represent a highly complex or novel capability.
