New Arch Check

description: Audit dependencies for New Architecture compatibility and maintenance status. Use when the user asks whether their libraries support the New Architecture or which dependencies are risky.

Audit the project's dependencies for New Architecture readiness and abandonment risk.

1. Read `package.json` and collect dependencies that ship native code or are React Native specific. Skip pure-JS utility packages; they are not the risk.

2. Run `npx expo-doctor@latest` and capture what it flags. It checks packages against React Native Directory metadata and catches known-incompatible and unmaintained ones. It needs the expo package; in a bare React Native project without it, skip to step 3 and query the directory for every native dependency.

3. For each remaining native dependency not covered by doctor output, query React Native Directory:
   `https://reactnative.directory/api/libraries?search=<package-name>`
   Note the New Architecture flag and the last-release recency. A package missing from the directory is not automatically bad, but combined with an old last-publish date it goes in the risk column.

4. Produce a single table: package, version, New Architecture status (supported / interop-expected / unsupported / unknown), last release age, and verdict. Three verdicts only:
   - keep: maintained and compatible
   - watch: works today via interop or unclear, has a pulse; recheck at the next SDK upgrade
   - replace: abandoned or incompatible; name the standard replacement (the new-architecture skill lists the usual swaps)

5. End with the two or three highest-risk items and one concrete next step for each. No generic advice; name packages and replacements.
