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.

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 deep understanding and practical application of Rust's asynchronous programming internals. It allows for optimization of async code, debugging complex concurrency issues, and building custom async runtimes or primitives. The skill focuses on the underlying mechanisms like futures, executors, and context switching within the async framework.

When to use it

  • Performance Tuning: Identify bottlenecks in existing asynchronous Rust applications and optimize critical sections for speed.
  • Debugging Async Code: Troubleshoot deadlocks, race conditions, or unexpected behavior in complex concurrent systems.
  • Custom Runtime Development: Build specialized async runtimes tailored to specific hardware or application requirements.
  • Compiler/Tooling Development: Develop tools that analyze and manipulate asynchronous Rust code.

Key capabilities

  • Understanding of Future traits and their implementation.
  • Knowledge of different executor types and their trade-offs.
  • Ability to debug async tasks and pinpoint concurrency issues.
  • Familiarity with context switching mechanisms in async runtimes.

Example prompts

  • "Explain how the select! macro works internally."
  • "What are some common causes of deadlocks in asynchronous Rust code?"
  • "How can I profile an async runtime to identify performance bottlenecks?"

Tips & gotchas

This skill requires a strong foundation in Rust fundamentals. A good understanding of ownership, borrowing, and lifetimes is essential for effectively utilizing the rust-async-internals skill.
