+#### Try the `upgrade-react-native` skill! (Experimental)
+
+Alongside 0.84, we've shipped an [experimental Agent Skill](https://skills.sh/react-native-community/skills/upgrade-react-native) to automate upgrades for Community CLI projects.
+
+Install the skill and run `/upgrade-react-native 0.84` from your AI coding agent of choice (supports [Claude Code](https://www.anthropic.com/claude/code), [Cursor](https://cursor.com), [Codex](https://openai.com/codex/) and others).

+```sh
+npx skills add react-native-community/skills
+```
+
+This is an experimental tool — always review changes and test thoroughly.
