Every prompt prefix worth keeping — across Claude, ChatGPT, Gemini, Copilot & DeepSeek. Most are community conventions, not official features: the model reads the intent. A handful (marked native) are real documented commands. Tap any card to copy.

How these work. No major AI lab ships an official registry of conversational prompt prefixes — they're shorthand the community converged on, and the model recognizes them because it saw them constantly in training. The top dozen are consistent; long-tail ones are hit-or-miss and can drift with model updates. They're portable: most work across any capable chat model (Claude, ChatGPT, Gemini, Copilot Chat, DeepSeek, Perplexity). Codes stack — try ACT AS: PM | SWOT | FORMAT AS: Table or /skeptic + ULTRATHINK. Pipe (|) chains them in order.
