code-review

Adversarial systems, concurrency, memory-model, and architecture code review protocol. Use this skill whenever asked to review code, PRs, diffs, or branches in Filament.

cpp-static-thread-safety

Enforce C++ static thread safety annotations and correct synchronization primitives. Use this skill when designing multi-threaded classes or editing guarded member fields.

filament-android-development

Build, deploy, run, and benchmark Filament binaries on connected Android devices or emulators. Use this skill for compiling, pushing, and executing Android tests or benchmarks.

filament-lifetime

Enforce correct Filament object creation and destruction lifecycles. Use this skill when initializing rendering pipelines or allocating/deallocating GPU buffers and entities.

filament-math

Enforce correct mathematical primitives and naming conventions in Filament code. Use this skill when performing coordinate transformations, vector math, or projection setups.

bindings-synchronization

Guidelines and SOP for synchronizing public C++ API changes (methods, enums, options structs) to Java (Android JNI) and JavaScript/TypeScript (Web/WASM Embind).

verification-protocols

Standard verification pipeline to execute after modifying C++ source or header files. Use this skill to format includes, build the engine, and run core tests.

cpp-header-inclusion

Enforce the strict topological header inclusion layering and reordering rules in Filament. Use this skill when adding or modifying `#include` directives in C++ source or header files.

filament-build-clean

Clean and build Filament targets for development, debugging, and production. Use this skill whenever you need to clean the workspace or compile desktop targets.

filament-desktop-testing

Execute unit tests and performance benchmarks for Filament on desktop platforms. Use this skill to run and filter tests or benchmarks locally.

header-self-containment

Enforce strict header self-containment so that every header file compiles independently. Use this skill when creating or modifying C++ header files.

preprocessor-guard-hygiene

Enforce preprocessor guard rules and macro-dependent inclusion hygiene in C++. Use this skill when modifying conditional imports or preprocessor directives.
