Upgrades a Capacitor plugin library from v8 to v9 (prerelease, @next until GA). Runs `npx @capacitor/plugin-migration-v8-to-v9@latest`, then the manual checklist - peer/dev dependency ranges, removed Android APIs (@NativePlugin, saveCall, pluginRequestPermission, int-code startActivityForResult, CapConfig getters, PluginCall.save/isSaved/hasOption), removed iOS APIs (CAPBridge class, getWebView, isSimulator, presentVC, CAPNotifications), AGP 9.2.1 / Gradle 9.5.1 build.gradle edits…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Capacitor Plugin Upgrade v8 to v9 Capacitor 9 is a prerelease (`next` dist-tag, 9.0.0-alpha.x as of October 2026). Dependency ranges below target the prerelease; after 9.0.0 GA use `^9.0.0` / `from: "9.0.0"`. Tell the user before publishing a stable plugin release that only supports a prerelease core; a common choice is to publish it under an npm `next` tag. Canonical source: https://capacitorjs.com/docs/updating/plugins/9-0 ## When to Use TRIGGER when: - Plugin repo with `peerDependencies["@capacitor/core"]` at `^8` or `>=8` and the user wants Capacitor 9 support - Plugin fails to compile against Capacitor 9 on removed APIs (`CAPBridge`, `@NativePlugin`, `saveCall`, `getWebView()`, `isSimulator()`) - Plugin's `android/build.gradle` fails under AGP 9 / Gradle 9 (`jcenter()`, `kotlin-android`, `proguard-android.txt`, namespace collision) - A consuming app without Cordova plugins fails on the plugin's `Cordova` SPM product or `com.getcapacitor.cordova` imports Do not use: - App projects -> `capacitor-app-upgrade-v8-to-v9` - Plugin still on 7 or older -> `capacitor-plugin-upgrades` (chain majors) - Adding SPM to a CocoaPods-only plugin -> `capacitor-plugin-spm-support` …

How to install
mdr add cap-go/capgo-skills/capacitor-plugin-upgrade-v8-to-v9@sha256:e1b8a981d965ad12The line at the top of this page pins the label git:20261011.86834d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
