memory-safety-patterns makes Claude reach for safer ways to manage memory and resources in Rust, C++ and C. It names six bug types (use-after-free, double-free, leaks, buffer overflow, dangling pointers and data races) and pairs each with a prevention, such as ownership, RAII, smart pointers, bounds checking or lifetime tracking.

The detailed reference has six patterns: RAII and smart pointers in C++, ownership in Rust, safe resource management in C, bounds checking and preventing data races. SKILL.md also lists debugging commands using AddressSanitizer, Valgrind, Rust Miri and ThreadSanitizer. The skill bundles no scripts.

Good for

  • C and C++ developers who want fewer leaks and use-after-free bugs
  • Rust developers who want to keep unsafe code to a minimum
  • Anyone choosing between manual memory, smart pointers, ownership and garbage collection

Install memory-safety-patterns

Claude Code

  1. 1

    Copy this prompt.

    Install the memory-safety-patterns skill in Claude Code. Run this command:

/plugin marketplace add wshobson/agents
/plugin install systems-programming@claude-code-workflows

Then check that it loaded and tell me how to use it.
  2. 2

    Paste it into Claude Code. It shows the change and asks before running it.

The plugin adds 3 skills, 4 agents (c-pro, cpp-pro, golang-pro, rust-pro) and 1 command (counted from the repo). Its marketplace entry lists no hooks or MCP servers. The skills CLI command installs only this skill, without the plugin's agents or commands (the README says so).

Built from the package data we hold. Not yet tested by us. Source.

What's in the skill

When it loads

Implement memory-safe programming with RAII, ownership, smart pointers, and resource management across Rust, C++, and C. Use when writing safe systems code, managing resources, or preventing memory bugs.

What it includes

  • Six bug types with a prevention for each.

    Use-after-free, double-free, memory leak, buffer overflow, dangling pointer and data race.

    Memory bug categories

  • Manual C, C++ smart pointers, Rust ownership, then garbage-collected languages.

    Trades control against safety.

    Safety spectrum

  • Prefer RAII and smart pointers; avoid raw pointers and careless unsafe.

    Also says not to return local references or ignore compiler warnings.

    Do and do not lists

  • Commands for AddressSanitizer, Valgrind, Miri and ThreadSanitizer.

    Compiles and runs your program under these tools. Miri uses cargo +nightly.

    Runs code · Debugging tools

  • Six patterns: RAII, smart pointers, Rust ownership, safe C, bounds checks, data races.

    Worked code examples in C++, Rust and C.

Permissions

Low risk

The skill is notes, but it lists commands that compile and run your program under debugging tools. Run them on code you trust, in a build folder you can delete.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • Debug commands build and run your code

    SKILL.md lists clang++ with -fsanitize, valgrind and cargo +nightly miri run. They run your program, so check it first. github.com

Questions

What does memory-safety-patterns do?

It gives Claude patterns for managing memory and resources safely in Rust, C++ and C. It covers RAII, smart pointers, ownership, bounds checking and avoiding data races.

How do I install memory-safety-patterns?

Use the install box above. On Claude Code the README route is the systems-programming plugin, which also adds 2 other skills, 4 agents and a command (counted from the repo). The skills CLI command installs only this skill.

Which languages does it cover?

Rust, C++ and C. SKILL.md also mentions Go and Java in its safety spectrum, as garbage-collected examples.

Does it need an API key?

SKILL.md names none, and the folder bundles no scripts. It holds SKILL.md and one reference file.

Is it safe to install?

The folder is two markdown files. SKILL.md lists commands for AddressSanitizer, Valgrind and Miri that run your own program, so run them on code you trust. The plugin route also adds agents and a command.

Which tools does it suggest for finding memory bugs?

AddressSanitizer on Clang or GCC, Valgrind, Rust Miri and ThreadSanitizer, with the commands in SKILL.md.
