- description
- Guides the agent through general Capacitor app development topics. Covers core concepts (native bridge, plugins, web layer), Capacitor CLI usage, app configuration (capacitor.config.ts, splash screens, app icons, deep links), platform management (Android, iOS, Electron, PWA), edge-to-edge and safe area handling on Android, live reload setup, storage solutions, file handling, security best practices, CI/CD references, iOS package managers (SPM, CocoaPods), and troubleshooting for Android and iOS. Do not use for creating new Capacitor apps, Capacitor plugin APIs, creating Capacitor plugins, in-app purchases, upgrading Capacitor versions, Cordova or PhoneGap migration, or framework-specific patterns (Angular, React, Vue).

Capacitor App Development
General guidance for developing cross-platform apps with Capacitor, covering core concepts, CLI usage, app configuration, platform management, and troubleshooting.
Prerequisites
- Capacitor 6, 7, or 8 app already created and initialized.
- Node.js and npm installed (Node 18+ for Cap 6, Node 20+ for Cap 7, Node 22+ for Cap 8).
- For Android: Android Studio installed.
- For iOS: Xcode installed on macOS.
Agent Behavior
- Auto-detect before asking. Inspect the project for platforms (
android/,ios/), framework (vite.config.ts,angular.json,webpack.config.js,next.config.js), Capacitor version (@capacitor/coreinpackage.json), and iOS dependency manager (ios/App/Podfilefor CocoaPods vs. SPM). - Route to the right reference file. Use the topic index below to identify the correct reference file and read it before providing guidance.
- One topic at a time. Address the user's specific question. Do not provide a general overview unless explicitly requested.
- Prefer actionable instructions. Provide exact file paths, commands, and diff blocks rather than conceptual explanations.
Procedures
Step 1: Identify the Topic
Match the user's request to a topic from the index below. If the request spans multiple topics, address them sequentially.
If the request matches a topic covered by a different skill, redirect the user to that skill (see Related Skills at the bottom).
Step 2: Analyze the Project
Auto-detect the following by reading project files:
- Capacitor version: Read
@capacitor/coreversion frompackage.json. - Platforms: Check which directories exist (
android/,ios/). - Framework: Check for build tool config files.
- Capacitor config format: Check for
capacitor.config.tsorcapacitor.config.json. - iOS dependency manager: Check for
ios/App/Podfile(CocoaPods) or SPM usage.
Step 3: Read the Reference File and Apply Guidance
Read the reference file for the matched topic and apply the instructions to the user's project.

Error Handling
npx cap syncfails: Verify@capacitor/coreand@capacitor/cliversions match. On iOS with CocoaPods, runcd ios/App && pod install. On Android, sync Gradle files in Android Studio.- Android build fails after configuration changes: Clean the build with
cd android && ./gradlew clean, then rebuild. - iOS build fails after configuration changes: Clean the build folder in Xcode (Product > Clean Build Folder) or delete
ios/App/Podsand runcd ios/App && pod install. - Plugin not found at runtime: Run
npx cap syncafter any plugin installation. Verify the plugin appears incapacitor.configor the native project. - Live reload not connecting: Verify the device and development machine are on the same network. Check that the server URL in
capacitor.configuses the correct LAN IP address. - Deep links not working: Verify the site association file is accessible at
https://<domain>/.well-known/apple-app-site-association(iOS) orhttps://<domain>/.well-known/assetlinks.json(Android). Verify the app is signed with the correct certificate.
