threejs-compatibility-fallbacks skillA
threejs-compatibility-fallbacks is agent-read markdown (skill) from linegel/threejs-complete-set-of-skill: Fallback unavailable WebGPU features through an isolated compatibility branch. Use only when the user explicitly asks how to handle an initialized non-WebGPU backend; then classify canonical behavior as preserved, weakened, or removed..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Three.js Compatibility Fallbacks Treat fallback as an explicitly authorized product branch. Canonical WebGPU/TSL work and native WebGPU quality tuning remain with their owning skills. ## 1. Activate the branch Record all of the following before selecting an implementation: - the user's explicit request for unavailable-WebGPU fallback; - proof from an initialized `WebGPURenderer` that `renderer.backend.isWebGPUBackend !== true` on the named target; - the canonical owner and exact feature; - the accepted scope of visual, physical, temporal, interaction, performance, and maintenance loss; - the compatibility branch's maintenance owner. Backend truth is available only after `await renderer.init()`. When WebGPU initializes, return to the canonical owner. When the explicit request is absent, report the unavailable-WebGPU blocker from the canonical path. Dispose the capability-probe renderer before constructing a separate compatibility renderer. This step is complete when the five activation facts are recorded and the canonical implementation remains unchanged. ## 2. Classify canonical behavior List the canonical feature's geometric, radiometric, color, temporal, …
