Agent Skills: Capacitor App Upgrade v5 to v6

Capacitor App Upgrade v5 to v6

Upgrade a Capacitor app from version 5 to version 6.

When to Use This Skill

• User says the app is on Capacitor 5 and must move to v6
• User wants the exact v5 to v6 migration path
• User needs v6-specific native and package updates

Live Project Snapshot

Current Capacitor packages from package.json: !node -e "const fs=require('fs');if(!fs.existsSync('package.json'))process.exit(0);const pkg=JSON.parse(fs.readFileSync('package.json','utf8'));const out=[];for(const section of ['dependencies','devDependencies']){for(const [name,version] of Object.entries(pkg[section]||{})){if(name.startsWith('@capacitor/'))out.push(section+'.'+name+'='+version)}}console.log(out.sort().join('\n'))"

Procedure

1. Start from the injected package snapshot and confirm the current @capacitor/core version.
2. Update all @capacitor/* packages to the v6-compatible range.
3. Review the v5 to v6 migration notes before editing native files.
4. Run npm install.
5. Sync with npx cap sync.
6. Verify the iOS and Android builds.

Error Handling

• If the automated migration misses a package, update it manually before syncing again.
• If iOS fails, check the deployment target and Xcode compatibility for Capacitor 6.
• If Android fails, check the Gradle and Java requirements for Capacitor 6.
