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 thebushidocollective/han at 19caa51d5f.

    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 enables AI agents to understand and utilize nullable types in C#. Nullable types allow value types (like int, bool, or DateTime) to be assigned a null value, which is crucial for representing missing or undefined data. It facilitates safer code by preventing potential NullReferenceException errors that are common when dealing with value types.

When to use it

  • Data validation: When processing user input where a field might legitimately have no value (e.g., optional age on a form).
  • Database interactions: Handling data from databases where columns can contain null values.
  • Legacy code migration: Converting older C# code that uses workarounds for representing missing value types to utilize nullable types.
  • API integration: Working with APIs that return value types which may be absent in certain scenarios.

Key capabilities

  • Understanding of Nullable<T> syntax.
  • Ability to assign and check for null values in value types.
  • Knowledge of the null-coalescing operator (??).
  • Awareness of nullable reference types (C# 8 and later).

Example prompts

  • "How do I declare an integer variable that can be null?"
  • "Explain the difference between int? and int in C#."
  • "Write a C# code snippet to safely access a nullable DateTime value, providing a default date if it's null."

Tips & gotchas

  • Requires a basic understanding of C# syntax.
  • Be mindful of potential null reference exceptions even when using nullable types; always check for null before dereferencing.
