Claude Code erne-feature for scoped Expo feature units

Keep React Native or Expo work to one screen, component, or hook with explicit types, states, and integration points.

Install in Claude Code

Use a full ERNE React Native or Expo project in Claude Code, including the configured feature-builder project agent. Confirm the agent variant in the generated configuration.

Review `.claude/skills/erne-feature/SKILL.md` and its requirements at the pinned GitHub commit.
Create `.claude/skills/erne-feature/` in your project and save the reviewed file as `.claude/skills/erne-feature/SKILL.md`.
Start Claude Code from that project's root, then select `/erne-feature` in the slash menu.

Example task

Feature feature-19 adds CourseEmptyCard only. Input is {loading: false, courseCount: 0, error: null}. The parent list already fetches data.

What to check

Deliver the presentation card and integration note, with {component: 'CourseEmptyCard', visibleText: 'No courses yet'}. Keep the parent fetch and established loading, error, and success behavior.

Frequently asked question

When does a feature need a broader implementation workflow?

Check the files and state boundaries first. Changes to navigation scaffolding, cross-screen state, or data layers call for the project’s broader workflow.
