Performs comprehensive C/C++ security review for memory corruption, integer overflows, race conditions, and platform-specific vulnerabilities. Use when auditing native C/C++ applications, reviewing daemons or services for memory safety, or hunting integer overflow / use-after-free / race conditions in userspace code.
Create and control VFX in Unreal Engine 5 with Niagara: systems and emitters, modules and the spawn/update stages, exposed User parameters, and spawning or driving effects from Blueprints or C++. Use when building particle effects, NS_/NE_ assets, spawning a Niagara system at runtime, setting User parameters, or when the user mentions Niagara, VFX, or a particle system in Unreal.
CPU cache optimization skill for C/C++ and Rust. Use when diagnosing cache misses, improving data layout for cache efficiency, using perf stat cache counters, understanding false sharing, prefetching, or structuring AoS vs SoA data layouts. Activates on queries about cache misses, cache lines, false sharing, perf cache counters, data layout optimization, prefetch, AoS vs SoA, or L1/L2/L3 cache performance.
WebAssembly with Emscripten skill for C/C++ to WASM compilation. Use when compiling C/C++ to WebAssembly with emcc, configuring EXPORTED_FUNCTIONS, understanding the WASM memory model, using Asyncify for async C code, debugging .wasm with browser devtools or wasm-opt, or targeting WASI vs browser environments. Activates on queries about Emscripten, emcc, WebAssembly from C/C++, WASM memory model, Asyncify, EXPORTED_FUNCTIONS, WASI, or wasm-opt.
GDB debugger skill for C/C++ programs. Use when starting a GDB session, setting breakpoints, stepping through code, inspecting variables, debugging crashes, using reverse debugging (record/replay), remote debugging with gdbserver, or loading core dumps. Activates on queries about GDB commands, segfaults, hangs, watchpoints, conditional breakpoints, pretty-printers, Python GDB scripting, or multi-threaded debugging.
Use this skill when working with UMG, UI, widget, UserWidget, Slate, HUD, BindWidget, Common UI, menu, or UMG binding in Unreal Engine. See references/widget-types.md for widget type reference and references/common-ui-setup.md for Common UI plugin setup. For Slate in editor tools, see ue-editor-tools. For input mode management, see ue-input-system.
CMake build system skill for C/C++ projects. Use when writing or refactoring CMakeLists.txt, configuring out-of-source builds, selecting generators (Ninja, Make, VS), managing targets and dependencies with target_link_libraries, integrating external packages via find_package or FetchContent, enabling sanitizers, setting up toolchain files for cross-compilation, or exporting CMake packages. Activates on queries about CMakeLists.txt, cmake configure errors, target properties, install rules, CPack, or CMake presets.
C++ library for reducing tail latency in RAM reads by hedging across multiple DRAM channels with uncorrelated refresh schedules
Use when the user is working with material, shader, MID, dynamic material, material instance, post-process, render target, parameter collection, decal, Nanite, Lumen, or rendering in Unreal Engine. See references/material-parameter-reference.md for parameter patterns and references/post-process-settings.md for post-process settings. For particle rendering, see ue-niagara-effects.
Debug and trace C/C++/Rust programs with the GNU Debugger (GDB) without blocking the agent. Use when you need to set tracepoints, inspect variables, or monitor a running process while staying responsive to the user.
MSVC cl.exe and clang-cl skill for Windows C/C++ projects. Use when configuring Visual Studio builds, MSBuild, or clang-cl as a drop-in MSVC replacement. Covers translating GCC/Clang flags to MSVC equivalents, runtime library selection, Windows SDK setup, and diagnosing MSVC-specific errors. Activates on queries about cl.exe, clang-cl, /O flags, /MT vs /MD, PDB files, Windows ABI, or MSVC project settings.
GCC compiler skill for C/C++ projects. Use when selecting optimization levels, warning flags, debug builds, LTO, sanitizer instrumentation, or diagnosing compilation errors with GCC. Covers flag selection for debug vs release, ABI concerns, preprocessor macros, profile-guided optimization, and integration with build systems. Activates on queries about gcc flags, compilation errors, performance tuning, warning suppression, or cross-standard compilation.
