Key takeaways
- Context you supply matters more than clever wording.
- Always specify the output format you want.
- A self critique pass is the cheapest quality gain available.
- Ask for options and tradeoffs rather than one confident answer.
- Reusable saved instructions beat retyping long prompts.
The four patterns
Role and audience. Say who is answering and who is reading. Answer as a tax accountant explaining to a first time freelancer changes vocabulary, depth and assumptions in one line.
Context dump. Paste the actual material. Real numbers, real constraints, real prior attempts. This is where most quality comes from.
Explicit output shape. Name the format, the length and the sections. A table with named columns produces far more accurate output than an open request.
Self critique. Ask for the answer, then ask what is weakest about it and to revise. Two passes beat one long prompt almost every time.
Writing and editing prompts
Rewrite this so a busy reader gets the point in the first sentence, cut every adjective that is not load bearing and keep my voice. Show the edited version and a short list of what you cut and why.
Here is my draft and here is the audience. List the three questions this reader will have that the draft does not answer, then write the missing sections.
Turn these rough notes into a structured brief with a summary, the decision required, the options with tradeoffs and a recommendation.
Research and analysis prompts
Give me a table of the main options for this problem with columns for the option, the strongest argument for it, the strongest argument against it and who it suits. Mark anything you are unsure about.
Argue the opposite of my current position as strongly as you can, using the same evidence I have given you.
Read these documents and list only the claims that contradict each other, with the page or section for each.
Work and productivity prompts
Here is my meeting transcript. Produce decisions made, owners with dates, open questions and anything a person disagreed with that was not resolved.
Act as a sceptical reviewer of this plan. List the assumptions it depends on, then rank them by how much damage a wrong assumption would cause.
Turn this process description into a step by step checklist a new hire could follow without asking questions, and flag the steps where mistakes are most likely.
Learning prompts
I will explain this topic in my own words. Do not correct me until I finish, then list what I got wrong, what I got right and what I left out.
Quiz me on this material with one question at a time, increasing difficulty, and do not give me the answer until I have attempted it.
Explain this at three levels, one for a beginner, one for a practitioner and one for an expert, and tell me which level my question came from.

Frequently asked questions
Do long prompts work better?
Longer context works better. Longer instructions do not. Add facts and constraints, not adjectives.
What is the single best ChatGPT prompt?
There is no single best prompt, but the highest return habit is asking the model to critique and revise its own first answer.
Should I still learn prompt engineering in 2026?
Yes, though it is now about supplying context and defining output rather than magic phrasing. Models fix wording, not missing information.
How do I reuse prompts?
Save them as custom instructions or projects in the tool so the context loads automatically instead of being pasted each session.
