cedmandocdoc Composing React Native Application
Overview
Extends one complete Expo core app into product variants through declared slots. Variants fill those slots; they keep the app rather than forking it. A host that prebuilds wraps the core’s toolchain factories so the filled variant can run. That wrap is host duty, not a slot.
Two unrelated apps that share a UI kit are a library plus managing-monorepo, not this skill.
Dependencies
Resolve every required row before composing. Skill discovery and missing-skill stop text: composition-contract.md → Require managing-monorepo.

Agent workflow
Follow this skill when one Expo core app is extended into product variants through slots. Match Entry points. When the variant package prebuilds, creating-variant.md points at host wrap. Core screens and src/ui use building-react-native-application when that optional skill is installed.
Entry points
Use the first matching row; combine when the task spans types.
| Entry | When | Go to |
|---|---|---|
| Fill slots / new variant | Identity, home tab, theme, extra routes | creating-variant.md |
| New slot on the core | Product behavior every variant should be able to pass in | creating-slot.md |
| Lookup | Known doc name or single reference | Reference index |
Task types
Match every row that applies. Open every local link in Docs before coding.
| Task type | Docs |
|---|---|
| Identity-only product | creating-variant.md |
Swap Main for an existing screen |
creating-variant.md |
| New home screen or shell-only feature | creating-variant.md; also building-react-native-application when installed |
| Declare a new slot | creating-slot.md |
Reference index
Contract
composition-contract.md — naming, structure, slots, host toolchain, skill dependencies.
| Doc | When to use |
|---|---|
| composition-contract.md | Naming, structure, product slots, kinds, dependency invoke |
| creating-variant.md | Fill declared slots |
| creating-slot.md | Add an extension point on the core |
| managing-shared-config.md | Host wrap after filling slots (prebuild package) |
