Install target

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 mindrally/skills at 7682ca7771.

    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 enables AI agents to write, debug, and refactor code specifically within the Kotlin programming language. It supports generating new modules, fixing syntax errors, and optimizing backend logic tailored for JVM environments.

When to use it

  • You need to generate a new Android library module or a Spring Boot service from scratch.
  • Your agent must refactor legacy Java codebases to improve type safety and null handling.
  • You require unit test generation for existing Kotlin functions using JUnit or Kotest.
  • The project needs migration assistance from older Kotlin versions to the latest stable release.

Key capabilities

  • Writing idiomatic Kotlin syntax with proper data classes and coroutines.
  • Debugging runtime exceptions specific to the JVM ecosystem.
  • Refactoring code to utilize modern features like sealed classes and extension functions.
  • Generating comprehensive unit tests for backend logic.

Example prompts

  • "Create a Spring Boot controller that accepts JSON payloads and returns a 201 status code."
  • "Refactor this function to use suspend functions instead of callbacks for asynchronous database calls."
  • "Write a unit test for the UserService class using Kotest with mocked repositories."

Tips & gotchas

Ensure your agent has access to the Kotlin compiler and standard library documentation to avoid version-specific errors. While powerful, complex concurrency patterns in Kotlin may require specific context about your project's threading model to implement correctly.
