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.

Item	Required	When	How
managing-monorepo e0e993e7-a5f9-4bea-9923-166b503df045	required	Always	npx skills add cedmandocdoc/awesome-skills --skill managing-monorepo
building-react-native-application ddfed93c-f419-4c5f-8832-85acc8f85f00	optional	Screens, src/ui, navigation, forms	npx skills add cedmandocdoc/awesome-skills --skill building-react-native-application

Install both: npx skills add cedmandocdoc/awesome-skills --skill composing-react-native-application --skill managing-monorepo

Setup

Item	Required	When	How
Standing rule	required	Fill slots / new variant	Add - Variants of `<core>` follow composing-react-native-application; load it before adding a variant or slot. to root AGENTS.md (create when missing) and to root CLAUDE.md when it exists without importing AGENTS.md; skip a file that has it

Agent workflow

Follow this skill when one Expo core app is extended into product variants through slots. Resolve every required Dependencies and Setup row, then 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)
