List files changed by React Native Upgrade Helper / rn-diff-purge for a version upgrade.
AI agents call list_changed_files to retrieve information from Rn Upgrade Helper without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves and lists files that changed between React Native versions. It fetches diff data from an external source (rn-diff-purge) without modifying, executing, or deleting anything. Pure read/query operation with minimal blast radius.
