Test

facebook/reactOfficial

This handles React's multi-channel testing setup so you don't have to remember which yarn command maps to which release channel. You can run tests against source, experimental, stable, www-modern, or www-classic with simple arguments like `/test experimental ReactFiberHooks`. The skill enforces the --silent and --no-watchman flags that prevent common sandboxing issues. It also reminds you about the two www variants when testing __VARIANT__ flags, which is easy to forget. If you're working on React core and need to verify behavior across different build configurations, this saves you from context-switching to documentation every time you want to run a test suite.
