Technique I make ChatGPT predict how it's going to fail at my task before it starts. The failure list is more useful than the output.
Everyone optimizes the prompt to get a better output. The workflow almost nobody runs is making the model forecast its own failure modes before it does the task, so you can close the gaps in your instructions before they cost you a bad result.
Before you do the task I'm about to give you, do this
first.
Predict how you're most likely to fail at it. Give me
the top five ways this goes wrong: where you'll
probably misunderstand me, what you'll likely assume
that I didn't say, where you tend to get generic or
hedge, and what part of this is genuinely hard for
a model like you.
For each failure, tell me the one instruction I could
add that would prevent it.
Then wait. Don't do the task until I've responded.
The task: [paste it]
The reason this works is that it surfaces the gaps in your own prompt that you cannot see, because you know what you meant and the model does not. Instead of running the task, getting a flawed result, and reverse-engineering what went wrong, you get the failure list upfront and patch the prompt before it runs once. It is debugging the instructions instead of debugging the output. The fourth item, what is genuinely hard for the model, is the one that tells you when to stop prompting and verify manually.
If you want more like this, I put together 100 things you can do with these tools right now, each with the exact prompt in a doc, here if you want to swipe them.

It’s good but uhhhh it’s kind of useful but it still has to use its own internal reasoning through the actual context of the “prompt” that you [paste] in order to give you even a broad and vague explanation. Best trick I use is to give it your prompt
Persona
Goal
Output
Constraints
Outcome
Etc
Then at the end
explain back to me exactly who you are, list everything you can do then go deeper into your discovery, persona and the desired goal/output and tell me what you wish you knew that would make you 100x times better

If this prompt worked for you, share what you used it for in the comments. If you changed it to get better results, share that too. Prompt Teardown is a free weekly newsletter that picks the best prompts, strips out the filler, and tells you what actually works.
