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 goooice/rust-skills at 57af2e8da9.

    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, goooice-m03-mutability, focuses on enabling AI agents to understand and work with mutable data structures in Rust. It allows the agent to reason about how changes to variables affect program state, and to write code that correctly manages ownership and borrowing when dealing with mutability. The skill provides a foundational understanding of Rust's core concepts related to data modification.

When to use it

  • Refactoring existing Rust code: The agent can identify sections where mutable variables are used and suggest improvements for clarity or safety.
  • Implementing algorithms requiring in-place modifications: For tasks like sorting or searching, the skill helps write efficient code that modifies data directly.
  • Debugging issues related to shared mutable state: When encountering unexpected behavior due to concurrent access, the agent can analyze the code and pinpoint potential problems.
  • Writing tests for functions modifying data: The agent can generate test cases specifically designed to verify correct mutation of variables.

Key capabilities

  • Understanding of mutable variable declarations (mut)
  • Reasoning about ownership and borrowing in relation to mutability
  • Identifying potential race conditions related to shared mutable state
  • Generating code that correctly modifies data structures

Example prompts

  • "Explain how mut affects the lifetime of a borrowed value."
  • "Refactor this function to avoid unnecessary copying by using mutable references."
  • "Write a unit test for this function that verifies it correctly updates the counter variable."

Tips & gotchas

This skill assumes a basic understanding of Rust syntax and data types. Incorrect use can lead to memory safety issues, so careful review of generated code is essential.
