What it does
Rnn Codebase is an agent skill from wix/react-native-navigation, published by the product's own GitHub organization. Navigate and work with the react-native-navigation (RNN) codebase. Use when fixing bugs, adding features, tracing command flows, understanding options resolution, or working across JS/iOS/Android layers in this repo.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Cross-platform mobile apps. It works with React Native, iOS and Android. The repository describes itself as: A complete native navigation solution for React Native. The licence is MIT.
When your agent uses it
- Adding features
- Tracing command flows
- Understanding options resolution
- Working across JS/iOS/Android layers in this repo
Example prompts
- “/rnn-codebase”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Navigation.push() → Commands.ts → processing pipeline → NativeCommandsSender.ts
- TurboModule: RNNTurboModule (iOS) / NavigationTurboModule.kt (Android)
- iOS: RNNCommandsHandler → RNNViewControllerFactory → UIKit controllers
- Android: Navigator → LayoutFactory → View-based controllers (no Fragments)
What it can do on your machine
Read from SKILL.md and the folder at commit 1de39e0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
yarn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use yarn, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Rnn Codebase loads about 2k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 610 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

React Native Navigation Codebase
Architecture Overview
RNN has three layers that mirror each other:
JS/TS (src/) → TurboModule bridge → iOS native (ios/)
→ Android native (android/)A navigation command (e.g. push) flows:
Navigation.push()→Commands.ts→ processing pipeline →NativeCommandsSender.ts- TurboModule:
RNNTurboModule(iOS) /NavigationTurboModule.kt(Android) - iOS:
RNNCommandsHandler→RNNViewControllerFactory→ UIKit controllers - Android:
Navigator→LayoutFactory→ View-based controllers (no Fragments)
Read ARCHITECTURE.md for the full overview.
Key Cross-Layer Mappings
Layout Types → Native Controllers
| JS Layout Type | iOS Controller | Android Controller |
|---|---|---|
component | RNNComponentViewController | ComponentViewController |
stack | RNNStackController (UINavigationController) | StackController |
bottomTabs | RNNBottomTabsController (UITabBarController) | BottomTabsController |
sideMenu | RNNSideMenuViewController (MMDrawerController) | SideMenuController (DrawerLayout) |
topTabs | RNNTopTabsViewController | TopTabsController (ViewPager) |
splitView | RNNSplitViewController | N/A (iOS only) |
externalComponent | RNNExternalViewController | ExternalComponentViewController |
Options → Presenters
Each controller type has a Presenter that applies options to views:
| iOS Controller | iOS Presenter | Android Presenter |
|---|---|---|
RNNComponentViewController | RNNComponentPresenter | ComponentPresenter |
RNNStackController | RNNStackPresenter + TopBarPresenter | StackPresenter |
RNNBottomTabsController | RNNBottomTabsPresenter | BottomTabsPresenter |
RNNSideMenuViewController | RNNSideMenuPresenter | SideMenuPresenter |
Events (same names both platforms)
| Event | Trigger |
|---|---|
RNN.ComponentDidAppear | Screen becomes visible |
RNN.ComponentDidDisappear | Screen hidden |
RNN.NavigationButtonPressed | TopBar button tap |
RNN.BottomTabSelected | Tab changed |
RNN.ModalDismissed | Modal dismissed |
RNN.ScreenPopped | Screen popped from stack |
RNN.CommandCompleted | Any command finished |
Where to Find Things
By task: "I need to fix/change X"
| Task | JS File(s) | iOS File(s) | Android File(s) |
|---|---|---|---|
| Command execution | src/commands/Commands.ts | ios/RNNCommandsHandler.mm | react/NavigationTurboModule.kt |
| Layout creation | src/commands/LayoutTreeParser.ts | ios/RNNViewControllerFactory.mm | options/LayoutFactory.java |
| Options processing | src/commands/OptionsProcessor.ts | ios/RNNNavigationOptions.mm | options/Options.java |
| Options application | — | ios/*Presenter.mm | viewcontrollers/*Presenter.java |
| TopBar | src/interfaces/Options.ts (TopBarOptions) | ios/TopBarPresenter.mm, ios/RNNUIBarButtonItem.mm | views/stack/topbar/ |
| Bottom tabs | src/interfaces/Options.ts (BottomTabsOptions) | ios/RNNBottomTabsPresenter.mm | viewcontrollers/bottomtabs/ |
| Modals | src/commands/Commands.ts | ios/RNNModalManager.mm | viewcontrollers/modal/ModalStack.java |

| Component registration | src/components/ComponentRegistry.ts | — | — |
| Deep linking (URL → screen) | src/linking/ (LinkingHandler, URLParser, RouteMatcher, DeferredLinkQueue, ModalLayoutBuilder) | ios/RNNAppDelegate.mm (dispatchDeepLinkURL:, cold-start queue, RCTContentDidAppearNotification) | NavigationActivity.onNewIntent → ReactGateway |

Options Resolution Order
Options are applied in ascending priority:
- Default options (from
Navigation.setDefaultOptions()) — lowest priority - Static options (from component class or
Navigation.registerComponent) - Options passed in the layout call (e.g.
push,setRoot) mergeOptions()— runtime override, highest priority
JS Processing Pipeline (exact order)
API layout → OptionsCrawler.crawl() → LayoutProcessor.process()
→ LayoutTreeParser.parse() → LayoutTreeCrawler.crawl()
→ OptionsProcessor (colors, assets, custom) → NativeCommandsSenderShow full SKILL.md (262 more words)Show less
iOS Patterns
- All controllers conform to
RNNLayoutProtocol RNNBasePresentersubclasses apply options —applyOptionsOnInit:,applyOptions:,mergeOptions:resolvedOptions:- Commands run on main thread (
RCTExecuteOnMainQueue) - React views:
RNNReactViewwrapsRCTSurfaceHostingView(new arch) - Overlays use separate
UIWindowinstances (RNNOverlayWindow) RNNReactComponentRegistrycaches React component instances
Android Patterns
- View-based, NOT Fragment-based
- All commands dispatched via
UiThread.post() ViewController<T extends ViewGroup>is the base —createView()is abstractParentControllerextendsChildControllerextendsViewController- Bottom tabs use
AHBottomNavigationlibrary - Three root layouts in
NavigationActivity: rootLayout, modalsLayout, overlaysLayout - Tab attachment modes:
Together,OnSwitchToTab,AfterInitialTab

Common Gotchas
- iOS uses UIKit subclasses (UINavigationController, UITabBarController); Android uses custom View hierarchy
splitViewis iOS-only- Side menu: iOS uses MMDrawerController (3rd party); Android uses DrawerLayout (native)
- Options that exist in JS types may not be implemented on both platforms — check the presenter
passPropsare stored in JSStore, not sent to native (cleared before bridge crossing)- The
lib/folder is generated — never edit it, editsrc/instead - Deep links are processed only after the first
setRoot()resolves; pre-bridge URLs on iOS are queued natively inRNNAppDelegateand flushed onRCTContentDidAppearNotification(bridgeless mode —RCTJavaScriptDidLoadNotificationdoes NOT fire) ModalLayoutBuilderstrips React-reserved keys (ref,key) from URL query params before they reachpassProps, to avoid React 19 ref-validation crashes
