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 passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • 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 undeclared network calls: passed

    Makes no network calls.

    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.

  • 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 personamanagmentlayer/pcl at 79ccaa9820.

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

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides expert guidance for Kotlin development, covering a wide range of areas including Android application development, Kotlin Multiplatform projects, and modern JVM backend solutions. It can assist with code generation, debugging, refactoring, and architectural decisions related to Kotlin programming. The skill demonstrates proficiency in core Kotlin concepts like null safety, extension functions, data classes, and coroutines, as well as frameworks such as Jetpack Compose and Retrofit.

When to use it

  • You're building an Android application using Jetpack Compose or other modern Android technologies.
  • You need help designing a shared business logic layer for Kotlin Multiplatform projects targeting both iOS and Android.
  • You are refactoring existing Kotlin code to improve its readability, maintainability, or performance.
  • You want assistance with implementing coroutines and Flow for asynchronous operations and reactive programming.
  • You're developing backend services using modern Kotlin syntax and best practices.

Key capabilities

  • Kotlin Fundamentals (Null safety, Extension functions, Data classes, Sealed classes)
  • Android Development (Jetpack Compose, ViewModel, LiveData, Room database, Retrofit, Dependency Injection with Hilt, Android lifecycle)
  • Kotlin Multiplatform (Shared business logic, Platform-specific implementations, iOS and Android targets, Common module architecture)
  • Modern Kotlin Syntax (data classes, sealed classes, extension functions, scope functions, when expressions)
  • Coroutines and Flow for asynchronous programming.

Example prompts

  • "Generate a data class representing a User with fields for id, name, email, and creation date."
  • "How can I use Kotlin's safe call operator to avoid null pointer exceptions?"
  • "Show me an example of using coroutines and Flow to fetch user data from a remote API."

Tips & gotchas

  • The skill is focused on Kotlin development; it won’t help with other programming languages.
  • While the skill covers Android development, it's not a complete replacement for dedicated Android development tools or expertise.
