Prompting skill is mostly pattern recognition: the same eight structures cover most marketing work a chatbot will ever do for you. Learn them once, reuse them forever — the difference between "the AI is useless" and "the AI is my intern" is almost always which pattern the human used.

1. The Persona Brief. "You are a [role] with [expertise], writing for [audience] who believes [misconception]." Roles constrain voice and vocabulary instantly — the single highest-leverage sentence in prompting. 2. The Few-Shot Style Lock. Paste two paragraphs of your own writing: "Match this voice exactly — rhythm, length, attitude." Models imitate samples far better than adjectives; "make it professional" means nothing, your actual paragraphs mean everything.

3. The Constraint Stack. Specify the fences: length, reading level, forbidden phrases, must-include facts, structure. "Under 150 words, no adjectives ending in -ing, must mention the 2026 price change, end with a question." Constraints convert generic output into deliverables. 4. The Critic Loop. Generate, then follow with: "Now critique this as a skeptical [editor/customer] — what's weak, generic or unverified?" Then regenerate against the critique. One self-review cycle reliably upgrades drafts.

5. The Table Forcer. Ask for output as a table with named columns — decisions become comparable, gaps become visible. "Five landing page variants: headline | angle | proof element | risk." 6. The Chain-of-Steps. "First list the customer's objections, then address each." Forcing the intermediate step produces reasoning the one-shot prompt skips.

7. The Anti-Generic Mandate. "List the six things every competitor says on this topic. Exclude all of them." Inverting the consensus is the fastest originality trick that exists. 8. The Source Discipline. "Only use facts from the text below; say 'not specified' otherwise." Grounding instructions cut hallucination dramatically for anything factual.

Combine freely — the real power is stacks: persona brief, style lock, constraints, table output, critic loop. That five-layer prompt is the difference between a toy and a staff writer who works in seconds and never gets tired of revisions.
