fetch-diff

Quick Review

This skill provides a focused utility for fetching PR diffs with filtering and line numbering. The description is clear and the usage is straightforward, making it easy for a CLI agent to invoke. The structure is clean and appropriate for a single-purpose skill. However, it provides moderate novelty since basic PR diff fetching can be done with standard git/GitHub CLI commands, though the auto-filtering and line numbering adds some value. Task knowledge is adequate with clear examples, but lacks details on what constitutes 'auto-generated files' and filtering criteria, which could be important for understanding the skill's behavior.
