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 mohitmishra786/low-level-dev-skills at bdc58472fa.

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

About this skill

What it does

The rust-unsafe skill enables AI agents to write and reason about Rust code that utilizes the unsafe keyword. This allows for direct memory manipulation, interacting with C libraries, and implementing low-level optimizations where standard Rust safety guarantees are insufficient. It facilitates tasks requiring fine-grained control over system resources and hardware interactions.

When to use it

  • Interfacing with C Libraries (FFI): When you need your Rust code to call functions from a C library that doesn't have safe Rust bindings.
  • Implementing Custom Memory Management: For scenarios requiring manual memory allocation, deallocation, or custom allocators beyond what the standard library provides.
  • Low-Level Hardware Access: When interacting directly with hardware devices where you need to bypass Rust’s safety checks for performance or compatibility reasons.
  • Optimizing Performance-Critical Code: In situations demanding maximum speed and efficiency, even at the cost of increased complexity and potential unsafety.

Key capabilities

  • Writing unsafe blocks in Rust code.
  • Working with raw pointers.
  • Implementing custom memory safety rules within unsafe contexts.
  • Interacting with foreign functions (FFI).

Example prompts

  • "Write a function that uses unsafe to call the C function 'my_c_function'."
  • "Generate Rust code for a custom allocator using raw pointers and unsafe operations."
  • “Show me how to create an unsafe block to access memory directly.”

Tips & gotchas

  • Requires a strong understanding of Rust's ownership system and borrowing rules. Incorrect use of unsafe can lead to undefined behavior.
  • Thoroughly document all unsafe code with clear explanations of the safety invariants being maintained.
