Universal resources
Universal resources skip vendor syntax, tool names and system-prompt tricks. They use plain instructions, an explicit output shape and clearly marked input, and every instruction-tuned model reads those. When a prompt needs a tweak to run somewhere else, the tweak is in the usage notes, not buried in the text.
