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 personamanagmentlayer/pcl at 79ccaa9820.

    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 guidance on C# development, specifically focusing on modern C# (version 12 and above), .NET 8+, ASP.NET Core, LINQ, asynchronous programming, and enterprise application development. It enables AI agents to generate clean, performant, and maintainable C# code adhering to industry best practices. The skill demonstrates features like primary constructors, collection expressions, record types (including immutable records, record classes with methods, and record structs), and pattern matching.

When to use it

  • Generating C# code snippets for backend applications.
  • Understanding and implementing modern C# language features (C# 12+).
  • Troubleshooting existing C# code or identifying areas for improvement.
  • Learning about best practices in .NET development, including LINQ and async programming.
  • Creating data structures using record types and understanding their immutability.

Key capabilities

  • Expert knowledge of modern C# (12+) features.
  • Proficiency in .NET 8+ and ASP.NET Core development.
  • Ability to write clean, performant, and maintainable code.
  • Understanding of LINQ for data querying and manipulation.
  • Experience with asynchronous programming techniques.
  • Knowledge of record types (immutable records, record classes, record structs).
  • Skill in utilizing pattern matching for conditional logic.

Example prompts

  • "Write a C# class representing a 'Person' using primary constructors."
  • "How can I use collection expressions to create an array of integers?"
  • "Show me an example of a record type with methods in C#."
  • “Explain how pattern matching works in switch expressions for customer discounts.”

Tips & gotchas

  • The skill focuses on modern C# features; older versions may not be fully supported.
  • It is designed specifically for backend development and might not cover all aspects of other .NET application types.
  • To get the best results, provide clear and specific instructions regarding desired functionality and coding style.
