⚠️ Common mistakes

Too long: Asking for “a summary” without a length limit can give you a wall of text. Always say “in three bullet points” or “in one short paragraph”.
Opinions sneaking in: AI can sound confident but invent opinions. Add the phrase “keep the language neutral and factual” to stay safe.
Skipping the check: Always glance back at the original to make sure the AI didn’t miss or change an important detail.
