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 aaronontheweb/dotnet-skills at e426ed93a9.

    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 implementing concurrency patterns in C#, such as using async/await, Task, and Parallel classes to write efficient, scalable, and thread-safe code. It covers best practices for managing asynchronous operations, handling race conditions, and optimizing performance in multi-threaded environments.

When to use it

  • Building high-performance backend services that handle multiple requests concurrently.
  • Writing applications that require parallel processing of large datasets or I/O-bound tasks.
  • Ensuring thread safety when working with shared resources in a multi-threaded C# application.

Key capabilities

  • Understanding and implementing async/await for asynchronous programming.
  • Using the Task class to manage background operations.
  • Applying synchronization primitives like lock, Semaphore, and Monitor.
  • Leveraging Parallel.For and Parallel.ForEach for data parallelism.

Example prompts

  • "Explain how to use async/await in C# to handle multiple HTTP requests concurrently."
  • "How can I prevent race conditions when updating a shared variable in a multi-threaded C# application?"
  • "Demonstrate the use of Task.Run and Task.WhenAll for parallel processing in C#."

Tips & gotchas

  • Be cautious with thread-local state and avoid blocking calls inside async methods.
  • Use ConfigureAwait(false) when calling async code from non-UI contexts to prevent deadlocks.
