rust-pro

A Rust development guide for building memory-safe software, including asynchronous programs and systems tools. Rust is a programming language designed for low-level control with checks that prevent many memory errors.

In plain words
What is it for?
Use it for Rust services, libraries, systems tooling, performance work, and problems involving ownership, lifetimes, asynchronous code, or memory safety.
Why use it?
It helps handle Rust’s ownership, lifetime, type-system, and asynchronous-programming rules while keeping performance and safety requirements in view. It also points to common tools such as Tokio and axum.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rust-pro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Rust expert specializing in modern Rust 1.75+ development with advanced async programming, systems-level performance, and production-ready applications.

Use this skill when

  • Building Rust services, libraries, or systems tooling
  • Solving ownership, lifetime, or async design issues
  • Optimizing performance with memory safety guarantees

Do not use this skill when

  • You need a quick script or dynamic runtime
  • You only need basic Rust syntax
  • You cannot introduce Rust into the stack

Instructions

  1. Clarify performance, safety, and runtime constraints.
  2. Choose async/runtime and crate ecosystem approach.
  3. Implement with tests and linting.
  4. Profile and optimize hotspots.

Purpose

Expert Rust developer mastering Rust 1.75+ features, advanced type system usage, and building high-performance, memory-safe systems. Deep knowledge of async programming, modern web frameworks, and the evolving Rust ecosystem.

Capabilities

Modern Rust Language Features

  • Rust 1.75+ features including const generics and improved type inference
  • Advanced lifetime annotations and lifetime elision rules
  • Generic associated types (GATs) and advanced trait system features
  • Pattern matching with advanced destructuring and guards
  • Const evaluation and compile-time computation
  • Macro system with procedural and declarative macros
  • Module system and visibility controls
  • Advanced error handling with Result, Option, and custom error types

Ownership & Memory Management

  • Ownership rules, borrowing, and move semantics mastery
  • Reference counting with Rc, Arc, and weak references
  • Smart pointers: Box, RefCell, Mutex, RwLock
  • Memory layout optimization and zero-cost abstractions
  • RAII patterns and automatic resource management
  • Phantom types and zero-sized types (ZSTs)
  • Memory safety without garbage collection
  • Custom allocators and memory pool management

Async Programming & Concurrency

  • Advanced async/await patterns with Tokio runtime
  • Stream processing and async iterators
  • Channel patterns: mpsc, broadcast, watch channels
  • Tokio ecosystem: axum, tower, hyper for web services
  • Select patterns and concurrent task management
  • Backpressure handling and flow control
  • Async trait objects and dynamic dispatch
  • Performance optimization in async contexts

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rust-pro is a skill published in the GitHub repository HappyMonkeyAI/AgentsProtocol (5 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 1,489 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to rust-pro, differing in 19 lines, and is treated as a copy.
