Rules with their reasons, a workflow, templates that compile in a real Expo app, and a definition of done that ends in a checker printing RESULT: PASS. Every checker is tested against planted bugs.
plugin marketplace add zakariaf/ReactNative-Skillsplugin install react-native@react-native-skillsAn example run: the forms-and-input checker reports onChange={field.onChange} on a TextInput at src/ui/form/code-field.tsx line 11 under rule field-on-change and prints RESULT: FAIL (1 problems); after the field binds onChangeText it prints RESULT: PASS.
Every checker is tested against planted bugs like these. One that stops catching its bug fails CI.
A zero-dependency Node script reads your repo and prints RESULT: PASS, or each problem with a file, line, rule and fix.
Each skill's self-test plants one bug per case that must fail for exactly its rule, and clean cases that must pass.
Complete files proven in a reference Expo SDK 57 app: strict TypeScript, ESLint with zero warnings, Jest and Prettier.
Expo Router, Zustand, TanStack Query, expo-sqlite, react-intl, Reanimated, Skia and EAS, with iOS and Android stated side by side.
A skill works installed alone, never points outside its folder, names every device it uses and stops to ask before anything outward-facing.
Claude Code plugins, a Codex manifest, AGENTS.md with an intent map, and a machine-readable skills.json.
A real one, from the catalogue below. Scroll through its parts.
A step-by-step workflow and a definition of done the agent can check, not a list of tips.
## Rules that must hold
9. Fields bind the React Native way: onChangeText, onBlur, ref.
Why: react-hook-form reads event.target.value, which a React Native change event lacks, so the field would hold undefined.
## Workflow
## Definition of done
☑ check-forms.mjs prints RESULT: PASS
Checked against Expo SDK 57 and React Native 0.86, and loaded only when the skill points to it.
Complete files, not snippets, proven inside a reference Expo app before they ship.
It reviews your code and prints RESULT: PASS or FAIL, each problem with a file, a line, a rule and a fix. Agents, CI and people read it the same way.
Start every task with react-native-conventions-index: it routes the task to the skills that apply and gives the build order.
# the marketplace, the core plugin, and the optional game skills
/plugin marketplace add zakariaf/ReactNative-Skills
/plugin install react-native@react-native-skills
/plugin install react-native-games@react-native-skillsSkills load on their own when a task matches; run one by name as /react-native:<skill> or /react-native-games:<skill>.
# the repository is a Codex plugin: .codex-plugin/plugin.json, skills in ./skills/
git clone https://github.com/zakariaf/ReactNative-SkillsInstall it the way your Codex version adds plugins from a Git repository. The Codex manifest ships all 79 skills; the game skills load only for game tasks.
# the open skills CLI places skills where your agent reads them
npx skills add zakariaf/ReactNative-Skills
npx skills add zakariaf/ReactNative-Skills --skill forms-and-inputThen give your agent AGENTS.md: how to pick, load and report, plus the intent map.
Search by task, file, error or tool. Each card says what the skill does, when to load it, and how to install it on its own.
