Native Data Fetching

Expo Networking

You MUST use this skill for ANY networking work including API requests, data fetching, caching, or network debugging.

When to Use

• Use this skill when:
• Implementing API requests
• Setting up data fetching (React Query, SWR)
• Using Expo Router data loaders (useLoaderData, web SDK 55+)
• Debugging network failures
• Implementing caching strategies
• Handling offline scenarios
• Authentication/token management
• Configuring API URLs and environment variables

Core Workflow

1. Confirm the request matches this skill's trigger, scope, and risk profile.
2. Use the topic map to identify the relevant pattern, checklist, or example before writing detailed guidance or code.
3. Load references/full-guidance.md when implementation details, examples, anti-patterns, validation checks, or edge cases are needed.
4. Apply only the relevant guidance instead of loading or repeating the entire reference by default.
5. Verify the result against any validation checks, limitations, security notes, or platform constraints in the reference.

Limitations

• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Progressive Loading

Keep this SKILL.md as the compact routing and workflow entrypoint. Load the reference file only when the user task requires the deeper implementation material.
