Read the official prompting guides
~15 minAnthropic and OpenAI both publish free prompt engineering guides that are better than any paid course. The core idea: be specific, give examples, assign a role, and break complex tasks into steps. That covers 80% of it.
Use prompt templates as starting points
~20 minDon't start from scratch. Sites like PromptHero and the ChatGPT prompt library have thousands of tested prompts. Copy one that's close to what you need, then modify it. Standing on the shoulders of giants.
Iterate with feedback loops
~25 minThe biggest prompt engineering secret: tell the AI what was wrong with its last answer and ask it to fix it. 'That was too formal, rewrite it casually' or 'Add more specific examples' works better than trying to write the perfect prompt upfront.
Test systematically for important prompts
~30 minIf a prompt matters (customer-facing, used repeatedly), test it 5-10 times with different inputs. Check for edge cases. Save your best prompts in a document. This is literally what professional prompt engineers do — there's no secret sauce.
When to hire instead
You're building a product that relies on AI and need production-grade prompts that work reliably at scale, with proper evaluation, guardrails, and edge case handling.
No time? Skip to hiringReal talk
You can learn 90% of prompt engineering in an afternoon. The free guides from Anthropic and OpenAI are better than most paid courses. The remaining 10% is just practice and iteration. Unless you're building a product with AI baked in, you almost certainly don't need to hire a prompt engineer.
