description

Design, implement, review, debug, and optimize modern Direct3D 11 rendering on Windows 10/11. Use for D3D11 devices and contexts, DXGI adapters and swap chains, shaders/HLSL, buffers, textures, resource views, render targets, depth/stencil, compute, synchronization, multithreading, device-lost recovery, WinUI 3 SwapChainPanel integration, C++/.NET/Rust interop, graphics diagnostics, and performance work.

Direct3D 11 Development

Use this skill for production Direct3D 11 / DXGI work on modern Windows.

Treat Direct3D 11 as an immediate/deferred GPU command API with implicit resource-state management. Keep device ownership, context ownership, resource lifetime, presentation, threading, and recovery explicit.

Reference documents

This skill is split across modular reference files in resources/. Load only the document(s) relevant to the current task.

How to use

1. Read resources/overview.md for the source-authority policy and baseline.
2. Read the specific resources/*.md documents for the task (device creation, resources, presentation, recovery, interop, performance, etc.).
3. Apply the guidance to the host project, preserving its existing abstractions and conventions.
