Write and review Rust, C++, and C code with safer memory and resource management. Covers ownership, automatic cleanup tied to scope, and smart pointers to help prevent leaks, double frees, and access to freed memory.
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.
Review the instructions the agent will receive before you install.
Cross-language patterns for memory-safe programming including RAII, ownership, smart pointers, and resource management.
| 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 |
Manual (C) → Smart Pointers (C++) → Ownership (Rust) → GC (Go, Java)

Build and review interfaces against WCAG 2.2 accessibility guidelines. Covers keyboard navigation, screen readers that read interface content aloud, accessible forms, mobile support, and display preferences, helping identify and fix barriers to using a website or app.
Review AI-generated code for problems hidden behind successful runs. Check failure handling, resource cleanup, unusual inputs, nonexistent dependencies, and departures from project conventions to identify missing safeguards before merging or accepting the work as complete.
Build Apache Airflow workflows for data pipelines and scheduled jobs. The skill guides task dependencies, retries, waiting for conditions, testing, and deployment, with patterns for tasks that can be safely rerun.
Plan and carry out an AngularJS to Angular migration, from choosing a rewrite strategy to converting components, services, and routes. Includes a hybrid approach that runs both frameworks together while individual features are migrated.
Identify software protections that hinder inspection, such as debugger detection and obfuscation that makes code harder to understand. Support authorized binary analysis and CTF security challenges with protection findings, bypass strategies, reports, and analysis scripts.
Design and review REST and GraphQL APIs with consistent naming, data structures, error responses, pagination for large result sets, and versioning strategies. Helps teams define shared standards and plan changes that existing clients can adopt gradually.
