## What it is
Khronos' official Vulkan validation layers that intercept Vulkan API calls to verify correct usage of the explicit Vulkan API, catching errors that drivers deliberately do not check. Includes core checks, synchronization validation, and GPU-assisted validation, and ships with the Vulkan SDK.

## Use cases
- debug invalid Vulkan API usage in my renderer
- catch synchronization errors between GPU commands
- find why my Vulkan app crashes on the GPU
- validate Vulkan descriptor and pipeline usage during development
- enable Vulkan validation on Android
- check correct use of Vulkan API without driver error checking

## When to choose
- developing or debugging Vulkan applications or engines
- you need authoritative, spec-compliant Vulkan error checking
- building on Windows, Linux, macOS, or Android with the Vulkan SDK

## When to avoid
- shipping in production release builds where overhead is unacceptable
- working with OpenGL, DirectX, or Metal instead of Vulkan
- you need a debugger/profiler UI rather than API validation

## Facets
- artifact type: library
- maturity: active
- function: testing, developer-tools, graphics
- domain: graphics, developer-tools, cross-platform
- platform: windows, cpp
- tags: vulkan, validation-layers, gpu, api-debugging, khronos, graphics-debugging, game-development, linux, macos, android
