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 booklib-ai/skills at c1b760abba.

    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 expertise in Kotlin, a modern programming language. It can assist with writing clean, concise, and efficient Kotlin code, including generating boilerplate, suggesting best practices, and debugging existing codebases. The skill is particularly useful for backend development tasks leveraging the Kotlin ecosystem.

When to use it

  • Generating Kotlin data classes or functions based on descriptions.
  • Refactoring existing Kotlin code for improved readability and maintainability.
  • Troubleshooting errors in Kotlin projects by analyzing error messages and suggesting fixes.
  • Creating unit tests for Kotlin code, ensuring functionality and robustness.

Key capabilities

  • Kotlin Code Generation
  • Code Refactoring Suggestions
  • Error Analysis & Debugging
  • Unit Test Creation

Example prompts

  • "Generate a Kotlin data class representing a 'Product' with properties: name, price, description."
  • "Refactor this Kotlin code snippet to use more idiomatic Kotlin features: [code snippet]"
  • "I'm getting a NullPointerException in my Kotlin code. Can you help me identify the cause?"

Tips & gotchas

This skill assumes some familiarity with Kotlin syntax and concepts. While it can generate basic code, understanding the underlying logic is still crucial for effective use.
