Prompt Engineering: Zero to Expert

Every great prompt has five components: Context (background info), Role (who the AI should be), Task (the specific action), Format (how you want the output structured), and Constraints (rules and boundaries). Not every prompt needs all five, but including more gives you more control. Think of it like ordering at a restaurant: the more specific your order, the closer the dish matches your expectation.

Zero-Shot means giving the AI a task with no examples. Few-Shot means providing 2-5 examples first so the AI learns the pattern. Use Few-Shot when: output format matters, the task is unusual, consistency is critical, or zero-shot gives inconsistent results.

Chain of Thought forces the AI to show reasoning before answering. Basic: add 'Let's think step by step.' Advanced: structure the reasoning with numbered steps. Tree of Thought: ask the AI to explore multiple reasoning paths and recommend the best. CoT is especially powerful for math, logic, analysis, planning, and debugging.

Writing: 'Act as [role]. Write [type] about [topic] for [audience]. Tone: [tone]. Length: [length].' Analysis: 'Analyze [data] for [focus]. Provide: key findings, patterns, implications, recommendations.' Code: 'Write [language] code that [does X]. Include comments, handle edge cases.' Brainstorming: 'Generate [number] ideas for [topic]. For each: summary, pros/cons, feasibility.' Summarization: 'Summarize in [number] key points. For each: main idea, supporting detail, why it matters.'

Meta-Prompting: ask the AI to write prompts for you. Prompt Chaining: break complex tasks into a series of simpler prompts where each output feeds into the next. Example: summarize → identify themes → suggest strategies → create timeline → write briefing. This gives much better results than one giant prompt. After each response, ask: 'Rate this 1-10. What would improve it?'

Image prompts: Subject + Style + Details + Mood + Technical. Be visual (describe what you see, not abstract concepts). Use style keywords: 'oil painting', 'cyberpunk', 'minimalist'. Add lighting: 'golden hour', 'dramatic'. Add camera: 'wide angle', 'macro'. Quality modifiers: 'highly detailed', '8K'. Negative prompts for what to avoid.

Professional cycle: Draft → Test (5-10 runs) → Analyze → Refine (one change at a time) → Document. Checklist: consistency, format match, edge cases, different inputs, correct tone. Save each version with date, changes, and result score. Build a prompt library organized by task type.
