Getting what you need from something long.
STEP ONE: DECIDE WHAT YOU NEED
Not "summarise this" but "what do I need to know from this".
Obligations? Deadlines? Costs? Changes from a previous version?
STEP TWO: UPLOAD OR PASTE IT
For very long documents, split into sections.
STEP THREE: ASK SPECIFICALLY
"Summarise this, focusing on [what you need]. Answer only from the document. If something is not in it, say so."
STEP FOUR: ASK FOR THE SOURCE
"Quote the passage supporting each main point."
STEP FIVE: CHECK THE QUOTES
Against the document. Confirm they exist and mean what is claimed.
STEP SIX: EXTRACT WHAT MATTERS
"List every date, deadline and amount mentioned."
STEP SEVEN: READ THE RELEVANT PART YOURSELF
If you will act on it, read that section properly.
WHAT THIS ACHIEVES
Reading a document you would otherwise not read, and knowing which part needs your attention.
