fetch-diff

Quick Review

A clear, well-structured skill for fetching PR diffs with line numbers. The description and usage example adequately explain invocation for a CLI agent. However, the skill provides moderate task knowledge - while the command is simple, details about the filtering logic, error handling, and what constitutes 'auto-generated files' are absent. The novelty is limited as fetching PR diffs is straightforward with GitHub APIs (though line numbering and filtering add some value). The structure is clean and appropriate for a single-function skill. Overall, a useful but relatively simple utility that doesn't represent significant complexity reduction.
