Java Kotlin Migration Assistant — Agent Skill by JetBrains

From the author

Migrate Java code to Kotlin in Spring-based codebases without changing behavior, public contracts, framework compatibility, or binary assumptions unless explicitly intended. Use when converting classes incrementally, replacing Lombok patterns, managing platform types and nullability, preserving JPA and proxy behavior, or planning the safe migration order of a mixed Java and Kotlin codebase.

Cardputer Buddy

Iterate on the Cardputer-Adv MicroPython app bundle (Claude Buddy, Snake, Hello) after the device is already provisioned via m5-onboard.

Trigger on "add an app", "push to the cardputer", "tail the device", "run on the device", or follow-up work after /maker-setup.
