Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add nonameplum/agent-skills --skill swift-async-stream-patterns -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

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 nonameplum/agent-skills at 26f9ebd26d.

    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 work with asynchronous streams in Swift, leveraging the latest concurrency features. It allows for efficient handling of data sequences that arrive over time, such as from network requests or file processing. The agent can transform, filter, and combine these streams to produce meaningful results.

When to use it

  • Real-time Data Processing: Analyzing live sensor readings or stock market updates as they become available.
  • Networked Applications: Handling data fetched from APIs that return streaming responses.
  • File Parsing: Efficiently processing large files by reading and acting on chunks of data incrementally.
  • Reactive Programming: Building responsive user interfaces that react to changes in asynchronous data sources.

Key capabilities

  • Asynchronous stream creation
  • Stream transformation (map, filter)
  • Stream combination (merge, zip)
  • Error handling within streams
  • Cancellation of ongoing operations

Example prompts

  • "Create a stream from this URL and print each line as it arrives."
  • "Filter the incoming data stream to only include values greater than 100."
  • “Combine two data streams, one containing user input and another with server responses.”

Tips & gotchas

  • Requires a working knowledge of Swift concurrency and asynchronous programming.
  • Be mindful of resource management when dealing with potentially infinite data streams to avoid memory leaks.
