Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install capacitor-plugin-8-to-9-upgrade

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent runs the official migrator for version 9, then removes deleted Android and iOS APIs, such as @NativePlugin and CAPBridge. It updates the Gradle files for AGP 9.2 and Gradle 9.5, with compileSdk 37 and minSdk 26, and iOS 16 in the podspec and Package.swift. You get a plugin compatible with the prerelease, ideally published under the next tag until Capacitor 9 is stable.
