vitorpamplona·vlatest·backend·MIT

Generates Kotlin Multiplatform code for shared mobile, desktop, and server backends, optimizing cross-platform development.

Repository

Install on your platform

This skill no longer installs under the name kotlin-multiplatform. SKILL.md frontmatter is not valid YAML, so the skills CLI skips it.

We check each listing against its upstream repository with the rules the skills CLI uses, last on 2026-10-22. We don't show a command we know will fail.

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: ktor.io.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    Hosts contacted

    github.comsource hostktor.ioundeclared

    What it found

    • .claude/skills/kotlin-multiplatform/scripts/suggest-kmp-dependency.sh:162contacts ktor.io
      echo "  - ktor: https://ktor.io/docs/client.html"

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned vitorpamplona/amethyst at c9670dfffa.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

The Kotlin Multiplatform skill enables AI agents to write and execute code that shares business logic across multiple platforms, including Android, iOS, Web, and Desktop. It allows a single codebase to target different operating systems while maintaining native performance through Kotlin/Native compilation.

When to use it

  • You need to share business logic between mobile (iOS/Android) and web applications without duplicating code.
  • Your project requires high-performance native execution on specific devices rather than relying solely on JavaScript bridges.
  • You want to leverage a single language ecosystem for cross-platform development while targeting diverse hardware architectures.
  • You are building backend services or shared libraries that must run efficiently on various client-side environments.

Key capabilities

  • Shares business logic across Android, iOS, Web, and Desktop platforms using a single codebase.
  • Compiles to native machine code via Kotlin/Native for optimal performance on each target platform.
  • Supports interoperability with existing Java, Swift, Objective-C, and C++ codebases.
  • Enables development of shared libraries that can be consumed by different build systems simultaneously.

Example prompts

  • "Create a Kotlin Multiplatform module to handle user authentication logic that works on both iOS and Android."
  • "Write a shared data model in Kotlin that serializes JSON responses for a web frontend and native mobile apps."
  • "Generate a cross-platform utility function to format dates consistently across all supported platforms."

Tips & gotchas

Ensure your AI agent understands the distinction between common code (shared logic) and platform-specific implementations when generating multiplatform projects. Be aware that while business logic is shared, UI code typically remains separate for each target platform to leverage native capabilities.
