memory-safety-patterns
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.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Memory Safety Patterns Cross-language patterns for memory-safe programming including RAII, ownership, smart pointers, and resource management. ## When to Use This Skill - Writing memory-safe systems code - Managing resources (files, sockets, memory) - Preventing use-after-free and leaks - Implementing RAII patterns - Choosing between languages for safety - Debugging memory issues ## Core Concepts ### 1. Memory Bug Categories | Bug Type | Description | Prevention | | -------------------- | -------------------------------- | ----------------- | | **Use-after-free** | Access freed memory | Ownership, RAII | | **Double-free** | Free same memory twice | Smart pointers | | **Memory leak** | Never free memory | RAII, GC | | **Buffer overflow** | Write past buffer end | Bounds checking | | **Dangling pointer** | Pointer to freed memory | Lifetime tracking | | **Data race** | Concurrent unsynchronized access | Ownership, Sync | ### 2. Safety Spectrum ``` Manual (C) → Smart Pointers (C++) → Ownership (Rust) → GC (Go, Java) Less safe More safe More control Less control ``` ## Detailed patterns and worked examples Detailed pattern documentation lives in `references/details.md`.

What does the memory-safety-patterns skill do?
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.
How do I install it?
Run `npx skills add wshobson/agents --skill memory-safety-patterns --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From wshobson/agents, a repository with 38,479 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
