August 8, 2026 ยท View on GitHub
Callstack Agent Skills give AI coding assistants practical React Native knowledge drawn from our work on production apps.
What's included
The skills are organized into three bundles.
| Plugin bundle | Use it for | Skills included |
|---|---|---|
| Building React Native Apps | Building, optimizing, navigating, upgrading, and extending React Native apps | Performance, navigation, TV, library creation, and upgrades |
| Testing React Native Apps | Writing tests, producing CI artifacts, automating devices, and running exploratory QA | GitHub Actions, React Native Testing, agent-device, and dogfood |
| Migrating to React Native | Assessing migration readiness and adopting React Native incrementally | Migration assessment and brownfield migration |
Quick start
Choose your assistant:
| Assistant | Setup |
|---|---|
| OpenAI Codex | Install from Plugins |
| All assistants | Manual installation |
OpenAI Codex
Open Plugins, search for react native, and install the bundle you need.
Manual installation
For Claude Code, Cursor, GitHub Copilot, Gemini CLI, OpenCode, and other compatible assistants, install all Callstack-maintained skills with the skills CLI:
npx skills@latest add callstackincubator/agent-skills --skill '*'
The CLI will ask which assistant and installation scope to use. To install only one skill, select it interactively or pass its name:
npx skills@latest add callstackincubator/agent-skills --skill react-native-best-practices
If your assistant does not support the skills CLI, see the AI Assistant Integration Guide for direct setup instructions.
Try it
Once installed, ask your assistant naturally. It will select the relevant skill from the task context.
Review this React Native screen for performance problems.
Plan an upgrade from this project's React Native version to the latest supported release.
Assess whether this native iOS and Android product should migrate incrementally.
Build downloadable iOS simulator and Android emulator artifacts in GitHub Actions.
Verify this checkout flow on iOS and capture evidence for any failures.
