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.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

    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-level assistance with Kotlin coroutines. It can help debug complex asynchronous code, optimize performance bottlenecks related to concurrency, and generate idiomatic coroutine implementations for various tasks. The skill understands advanced coroutine concepts like channels, flows, and structured concurrency.

When to use it

  • Debugging Asynchronous Code: You're encountering unexpected behavior or errors in your Kotlin coroutines-based application and need help identifying the root cause.
  • Performance Optimization: Your coroutine code is slow or inefficient, and you want suggestions for improving its performance through better concurrency patterns.
  • Implementing Complex Flows: You need to create a complex data pipeline using Kotlin flows but are unsure of the best approach.
  • Understanding Structured Concurrency: You're trying to implement structured concurrency with CoroutineScope and supervisor/launch and require guidance on proper usage.

Key capabilities

  • Debugging coroutine code
  • Optimizing coroutine performance
  • Generating Kotlin flow implementations
  • Explaining structured concurrency concepts
  • Understanding channels and actors

Example prompts

  • "My coroutine is throwing a CancellationException. Can you help me debug it?"
  • "How can I optimize this Kotlin flow to reduce latency?"
  • "Can you show me an example of using supervisor to handle multiple tasks concurrently?"
  • “Explain the difference between launch and async in coroutines.”

Tips & gotchas

  • The skill assumes a working knowledge of Kotlin programming. A basic understanding of asynchronous programming concepts is also beneficial.
