Clear context, constraints and review criteria usually matter more than elaborate prompt formulas.
State the outcome and audience
Explain what should be produced, who will use it and what decision or task it supports. This gives the system a practical target instead of a vague topic.
Provide boundaries and evidence
Specify length, tone, excluded claims and acceptable sources. If accuracy matters, ask for uncertainty to be identified and verify every important fact independently.
Improve one variable at a time
When a result misses the mark, change the clearest weakness rather than rewriting everything. Iteration becomes easier when examples and evaluation criteria remain stable.
