Before and after prompts for ChatGPT
Rough request on the left, the PromptDC rewrite on the right.
Before
What patterns do you see in these renewal call notes?
After
Analyze the pasted renewal call notes for recurring upgrade drivers. Group related themes and count how many notes support each one. Separate direct customer evidence from sales interpretation. Flag weak evidence, contradictions, and questions that need follow up.
Why this is better: The text adds evidence rules and a clear synthesis format so ChatGPT can produce defensible findings.
Before
Can this hotel get a Greek grant for heat pumps?
After
Research current Greek grants for a small hotel replacing oil heating with heat pumps. Prioritize official program pages and note the date each source was checked. Compare eligibility, program status, deadlines, subsidy rates, and required documents. State what remains uncertain and link every factual claim to its source.
Why this is better: The text adds source and comparison criteria so ChatGPT can return current, verifiable research.
Before
Why did this Postgres query get slow after I added row_number?
After
Analyze the pasted PostgreSQL query and its EXPLAIN ANALYZE output. Explain how the window function affects sorting, memory, and row processing. Do not invent measurements that are not present in the execution plan. Suggest two improvements, compare tradeoffs, and show safe ways to validate them.
Why this is better: The text anchors the diagnosis in supplied evidence so ChatGPT can suggest safer query improvements.
