Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add mcart13/dev-skills --skill rust-performance-best-practices -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

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 mcart13/dev-skills at 87cfd2a8fa.

    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 guidance on optimizing Rust code for performance. It covers techniques to reduce memory usage, improve CPU efficiency, and minimize runtime overhead. The skill aims to help developers identify bottlenecks and apply best practices for writing faster and more efficient Rust programs.

When to use it

  • You're experiencing slow execution times in a Rust application and need to profile and optimize its performance.
  • You’re designing new Rust code and want to proactively incorporate performance-enhancing techniques from the start.
  • You are working on resource-constrained environments (embedded systems, mobile devices) where efficient memory usage is critical.
  • You're preparing a Rust application for production deployment and need to ensure it meets performance requirements.

Key capabilities

  • Profiling Rust code
  • Memory management optimization
  • CPU efficiency improvements
  • Runtime overhead reduction

Example prompts

  • "Analyze this Rust code snippet and suggest optimizations for memory usage."
  • "What are the best practices for avoiding unnecessary allocations in Rust?"
  • "How can I profile my Rust application to identify performance bottlenecks?"

Tips & gotchas

This skill assumes a basic understanding of Rust programming concepts. While it provides guidance, practical experience with profiling tools and code optimization is beneficial for applying its recommendations effectively.
