## What it does

The skill reads the `@capacitor/core` version from `package.json` — `devDependencies` or `peerDependencies` — and works out the current major. Then it asks for the target version and defaults to 8. Each major jump maps to its own reference file: `references/upgrade-v4-to-v5.md`, `upgrade-v5-to-v6.md`, `upgrade-v6-to-v7.md`, `upgrade-v7-to-v8.md`.

Multi-version jumps run sequentially, and skipping intermediate versions is not allowed. After every step the agent runs `npm install && npx cap sync`, builds, and checks the plugin's test app. The guides cover Android SDK targets, Gradle configuration, Java/Kotlin versions and iOS deployment targets, plus a manual fallback for each version when the official migration tools fail.

Node.js and npm are required, and the minimum Node version depends on the target: 16+ for Capacitor 5, 18+ for 6, 20+ for 7, 22+ for 8. The project has to be a plugin, not an app — app projects belong to the separate `capacitor-app-upgrades` skill. If an Android build breaks after the upgrade, the skill points to **Tools > AGP Upgrade Assistant** in Android Studio.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add capawesome-team/skills --skill capacitor-plugin-upgrades -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add capawesome-team/skills --skill capacitor-plugin-upgrades -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/capacitor-plugin-upgrades/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add capawesome-team/skills --skill capacitor-plugin-upgrades -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/capacitor-plugin-upgrades/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install capawesome-team/skills capacitor-plugin-upgrades
```

2. **Manually: put the files in place**
- File: `.github/skills/capacitor-plugin-upgrades/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add capawesome-team/skills --skill capacitor-plugin-upgrades -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/capawesome-team/skills --path skills/capacitor-plugin-upgrades
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/capacitor-plugin-upgrades/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add capawesome-team/skills --skill capacitor-plugin-upgrades -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/capawesome-team/skills/tree/HEAD/skills/capacitor-plugin-upgrades/SKILL.md

## When to use it
- upgrade a Capacitor plugin from 4 to 8
- move a plugin from Capacitor 5 to 6 without skipping steps
- fix an Android build that fails after the upgrade
- apply manual steps where the automated migration tool broke
- verify the plugin's test app after each version jump

## Example prompts
- upgrade this Capacitor plugin to version 8
- move the plugin from Capacitor 5 to 7
- the Android build fails after the upgrade — what now

# Capacitor Plugin Upgrade

Upgrade a Capacitor plugin to a newer major version (4→5, 5→6, 6→7, or 7→8).

## Prerequisites

| Target Version | Node.js |
| -------------- | ------- |
| 5              | 16+     |
| 6              | 18+     |
| 7              | 20+     |
| 8              | 22+     |

The project must be a Capacitor plugin (not an app project).

## Procedures

### Step 1: Detect Current Version

Read `@capacitor/core` version from `package.json` (`devDependencies` or `peerDependencies`). Determine the current major version.

Ask the user for the target version. Default to the latest (8) if not specified.

### Step 2: Execute Upgrade

For each major version jump between the current and target version, apply the corresponding upgrade guide **sequentially**:

| Current → Target | Reference                            |
| ---------------- | ------------------------------------ |
| 4 → 5            | `references/upgrade-v4-to-v5.md`   |
| 5 → 6            | `references/upgrade-v5-to-v6.md`   |
| 6 → 7            | `references/upgrade-v6-to-v7.md`   |
| 7 → 8            | `references/upgrade-v7-to-v8.md`   |

For multi-version jumps (e.g., 5 → 8), apply each upgrade in order:
1. Read and apply `references/upgrade-v5-to-v6.md`
2. Run `npm install && npx cap sync`, build, and verify the plugin's test/example app
3. Read and apply `references/upgrade-v6-to-v7.md`
4. Run `npm install && npx cap sync`, build, and verify the plugin's test/example app
5. Read and apply `references/upgrade-v7-to-v8.md`
6. Run `npm install && npx cap sync`, build, and verify the plugin's test/example app

Do **not** skip intermediate versions.

### Step 3: Final Verification

After completing all upgrade steps:

```bash
npm install
npx cap sync
```
