Codex React Native skills
Codex React Native skills give a React Native team a fixed set of rules for Codex to follow, so screens come out the same way every time. Page one has one card for the stack, the free react native best practices architect. Per its page it covers native primitives, typed React Navigation 7 param lists and fast lists, and it audits existing screens for web habits; it leaves out React Native for Web, testing and accessibility. Run the audit on one existing screen before you ask for new ones. mobile app master is the broader option, so read its page before you pick.
iOS skills for Codex
A Codex iOS skill is the quickest way to get consistent SwiftUI. Start with iOS Swift Master and the free swiftui microinteractions; ask for one interaction at a time and check it on a device. Before you submit to the App Store, we would run App Privacy Manifest Consistency Gate and Mobile Store Compliance Auditor on the build you plan to submit. These iOS skills for Codex check your app, they do not replace the review. The two checks are paid and the microinteractions skill is free.
Android, Flutter and .NET MAUI
Other stacks are covered too. Android has Kotlin Android Master, plus Android Auth Pro and Android Networking for authentication and networking; add those when the app reaches that layer. Flutter has Flutter Cross Master and .NET MAUI has .Net MAUI Master. Check each against your framework version before the first task.
How to use mobile skills in Codex
Pick a skill by job: React Native, native iOS, native Android, cross-platform or store compliance. Mobile developers, iOS and Android specialists and app agencies use them. Connect Codex to Agensi once, then ask for a skill by name or let Codex choose it when the task matches its description. The latest approved version loads and nothing is saved to .agents/skills or $HOME/.agents/skills, so every app repo and teammate gets the same version. The MCP setup guide covers the connection. For skills you keep locally, see where Codex CLI skills are stored, and read using AGENTS.md with Codex.
How to choose a mobile skill in Codex
Pick the skill for your stack first and add a compliance check before each store submission. A broad skill such as mobile app master suits a team that works across stacks; a stack skill gives tighter rules. Check that the skill names your stack and version, read the preview and the security scan, and weigh free against paid. Our best mobile development skills for AI agents compares more.
