Prescriptive workflow for incremental adoption of React Native in existing native apps using @callstack/react-native-brownfield, from initial setup through phased host integration.
Migrating to React Native
Overview
Prescriptive workflow for incremental adoption of React Native in existing native apps using @callstack/react-native-brownfield, from initial setup through phased host integration.
- Expo track
- Bare React Native track
Use one track per task unless the user explicitly asks for migration or comparison.
Migration Strategy
Use this strategy for brownfield migration planning and execution:
- Assess app state and select Expo or bare path.
- Perform initial setup with
@callstack/react-native-brownfield. - Package RN artifacts (
XCFramework/AAR) from the RN source app. - Integrate one RN surface into the host app and validate startup/runtime.
- Repeat integration by feature/screen for incremental rollout.
Agent Guardrails (Global)
Apply these rules across all reference files:
- Select one path first (Expo or bare) and do not mix steps.
- Use placeholders from the docs (
<framework_target_name>,<android_module_name>,<registered_module_name>) and resolve from project files. - Validate each packaging command before moving to host integration.
- Prefer official docs for long platform snippets and CLI option details.
- Keep host apps isolated from direct React Native APIs when possible (facade approach).
Canonical Docs
- Quick Start
- Expo Integration
- iOS Integration
- Android Integration
- Brownfield CLI
- Guidelines
- Troubleshooting
Path Selection Gate (Must Run First)
Before selecting any reference file, classify the project:
- If no React Native app exists yet, use Expo creation path:
- If React Native app exists, inspect
package.jsonandapp.json:- Expo if
expois present or Expo plugin workflow is requested. - Bare RN if native folders and direct RN CLI workflow are used without Expo path requirements.
- Expo if
- If still unclear, ask one disambiguation question.
- Continue with exactly one path.
When to Apply
Reference this package when:
- Planning incremental migration from native-only apps to React Native or Expo
- Creating brownfield integration flows for Expo or bare React Native projects
- Performing initial setup with
@callstack/react-native-brownfield - Generating iOS XCFramework artifacts from a React Native app
- Generating and publishing Android AAR artifacts from a React Native app
- Integrating generated artifacts into host iOS/Android apps

How to use react-native-brownfield-migration on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your development machine
- ›Node.js version 16.0+ with npm package manager (verify with
node --version) - ›Active project directory or workspace where you want to add react-native-brownfield-migration
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
The skills CLI fetches react-native-brownfield-migration from GitHub repository callstackincubator/agent-skills and configures it for Cursor.
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Reload or restart Cursor to activate react-native-brownfield-migration. Access the skill through slash commands (e.g., /react-native-brownfield-migration) or your agent's skill management interface.
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Implementation Guide▌
Prerequisites
- ›Claude Desktop or compatible AI client with skill support
- ›Clear understanding of task or problem to solve
- ›Willingness to iterate and refine outputs
Time Estimate
15-45 minutes depending on use case complexity
Installation Steps
- 1.Install skill using provided installation command
- 2.Test with simple use case relevant to your work

- 4.Iterate on prompts to improve results
- 5.Integrate into regular workflow if valuable
Common Pitfalls
- ⚠Expecting perfect results without iteration
- ⚠Not providing enough context in prompts
- ⚠Using skill for tasks outside its intended scope
- ⚠Accepting outputs without review and validation
Best Practices▌
✓ Do
- +Start with clear, specific prompts
- +Provide relevant context and constraints
- +Review and refine all outputs before using
- +Iterate to improve output quality
- +Document successful prompt patterns
✗ Don't
- −Don't use without understanding skill limitations
- −Don't skip validation of outputs
- −Don't share sensitive information in prompts
- −Don't expect skill to replace human judgment
💡 Pro Tips
- ★Be specific about desired format and style
- ★Ask for multiple options to choose from
- ★Request explanations to understand reasoning
- ★Combine AI efficiency with human expertise

✓ Use When
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid When
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
Learning Path▌
- 1Familiarize yourself with skill capabilities and limitations
- 2Start with low-risk, non-critical tasks
