It reads everything. Literally.
A model predicts the most likely next words from all the text in front of it. It can't see your inbox, your policies or yesterday's meeting.
Only what's on the page
Rule 01
No hidden knowledge of your company, customers or projects unless you paste it, attach it or it's in the tool's memory.
THE FIX
Include the facts it needs. Don't assume it knows.
Every word is a signal
Rule 02
Your tone, examples and even your typos get echoed back. Casual prompt, casual answer.
THE FIX
Write the prompt in the style you want back.
Order matters
Rule 03
With long material, the model handles it best when the document comes first and your question comes last.
THE FIX
Paste the source, then ask.
Plausible isn't true
Rule 04
It generates what sounds right. When a fact is missing, it can fill the gap with a confident guess.
THE FIX
Give it the facts, then check the ones that matter.

If it's not in the prompt, it's a guess.
