## What it does

The skill runs `npx cap migrate` from `@capacitor/cli@latest-7`, then covers whatever the migration skipped or failed on. It carries a checklist for config, iOS, Android and official plugins, plus two references: `references/android.md` for hand-editing Gradle and the manifest, and `references/plugins.md` for broken types. A reference loads only when its topic is in play, so your context stays clean.

Check the environment before you start: Node 20+, Xcode 16+, Android Studio Ladybug with JDK 21, AGP 8.7.2 and Gradle 8.11.1. The skill reads your `@capacitor/*` versions from `package.json` and prints them in a project snapshot. It also flags that minSdk 23 and iOS 14 drop older devices — worth telling a client before the release, not after.

JDK is where things usually stall. Capacitor 7 Android modules compile against Java 21, so Gradle on JDK 17 dies with `invalid source release: 21`. Fix the JDK in your IDE and CI, not the code. Another trap: plugins that still peer on `@capacitor/core` `^6` throw `ERESOLVE` at install. Upgrade or replace them instead of reaching for `--legacy-peer-deps`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill capacitor-app-upgrade-v6-to-v7 -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/capacitor-app-upgrade-v6-to-v7/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/capacitor-app-upgrade-v6-to-v7/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill capacitor-app-upgrade-v6-to-v7 -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/capacitor-app-upgrade-v6-to-v7/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill capacitor-app-upgrade-v6-to-v7 -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/capacitor-app-upgrade-v6-to-v7/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Cap-go/capgo-skills capacitor-app-upgrade-v6-to-v7
```

2. **Manually: put the files in place**
- File: `.github/skills/capacitor-app-upgrade-v6-to-v7/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill capacitor-app-upgrade-v6-to-v7 -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Cap-go/capgo-skills --path skills/capacitor-app-upgrade-v6-to-v7
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/capacitor-app-upgrade-v6-to-v7/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill capacitor-app-upgrade-v6-to-v7 -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Cap-go/capgo-skills/tree/HEAD/skills/capacitor-app-upgrade-v6-to-v7/SKILL.md

## When to use it
- move an app from Capacitor 6 to 7 without skipped steps
- fix an Android build failing on the JDK 21 requirement
- strip `bundledWebRuntime` and `cordova.staticPlugins` from the config
- clear TypeScript errors on removed plugin types
- resolve `ERESOLVE` caused by plugins peering on `^6`

## Example prompts
- Upgrade my app from Capacitor 6 to 7
- The build fails with `Capacitor 7 requires JDK 21` — what do I do?
- \`Module '@capacitor/app' has no exported member 'AppUrlOpen'` — how do I fix it?

description: Upgrades a Capacitor app from v6 to v7 using `npx cap migrate` from `@capacitor/cli@latest-7`, then the manual checklist - Node 20+, Xcode 16+, iOS deployment target 14.0 (Xcode project and Podfile), Android Studio Ladybug with JDK 21, AGP 8.7.2, Gradle 8.11.1, minSdk 23, compile/target SDK 35, removed `bundledWebRuntime` and `cordova.staticPlugins` config, `navigation` in configChanges, and official plugin breaking changes (removed deprecated types like `AppUrlOpen`, `HapticsImpactStyle`, `DeviceBatteryInfo`; Device no longer returns disk sizes). Use when `@capacitor/core` is 6.x and the target is 7.x, or on errors like "Capacitor 7 requires JDK 21" or "Module 'X' has no exported member 'AppUrlOpen'". Do not use for other major versions, plugin library upgrades, or non-Capacitor apps.

# Capacitor App Upgrade v6 to v7

Move a Capacitor 6 app to Capacitor 7. Source of truth: https://capacitorjs.com/docs/updating/7-0

## When to Use

- `@capacitor/core` in the snapshot below is `6.x` and the user wants `7.x`.
- Build fails after bumping to 7 with JDK 21 / AGP 8.7 errors, iOS deployment target 13 errors, or TypeScript errors on removed deprecated plugin types.
- The user asks for the exact 6 -> 7 checklist.

Do not use:

- App on 5.x -> `capacitor-app-upgrade-v5-to-v6` first. On 7.x -> `capacitor-app-upgrade-v7-to-v8`. Multi-hop planning -> `capacitor-app-upgrades`.
- Plugin library upgrade -> `capacitor-plugin-upgrade-v6-to-v7`.
- CocoaPods to SPM -> `cocoapods-to-spm`.

## 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'))"`

## References

Only load a reference when its topic is in play.

| File | Load when |
| --- | --- |
| `references/android.md` | Editing `variables.gradle`, `build.gradle`, wrapper, manifest, or Kotlin by hand |
| `references/plugins.md` | The app uses official `@capacitor/*` plugins (App, Device, Haptics, Splash Screen, Status Bar, ...) |
