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: jsonplaceholder.typicode.com.

    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.

  • 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 clostaunau/holiday-card at d7c92b29e8.

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

About this skill

What it does

This skill provides Python code snippets demonstrating asynchronous programming patterns. It allows for concurrent execution of tasks, improving performance in I/O bound applications. The skill focuses on practical examples and best practices for writing efficient and readable asynchronous code.

When to use it

  • Building a web server: Implement non-blocking request handling to serve multiple clients concurrently.
  • Data processing pipelines: Parallelize data fetching and transformation steps for faster overall execution.
  • Real-time applications: Handle numerous concurrent connections in chat servers or game backends.
  • I/O intensive tasks: Speed up operations involving network requests, file reads/writes, or database queries.

Key capabilities

  • Asynchronous function definitions using async and await.
  • Event loop management for scheduling and running coroutines.
  • Concurrency primitives like asyncio.Semaphore for resource control.
  • Example code demonstrating common asynchronous patterns.

Example prompts

  • "Show me an example of how to use asyncio.gather to run multiple tasks concurrently."
  • "Generate a Python function that uses async/await to fetch data from two URLs in parallel."
  • “How can I implement rate limiting using asyncio.Semaphore?”

Tips & gotchas

  • Requires a basic understanding of Python and asynchronous programming concepts.
  • The skill provides code snippets; you may need to adapt them to your specific project's context.
