- Produce a verified list of decisions, open questions and deadlines, plus a draft of the one reply you owe.
You return from leave to a thread with forty messages and a vague “thoughts?” at the end. Summaries are tempting, but a summary that invents a decision or misses an open question is worse than reading it all. The safest approach is to ask for structured output tied to quotes.
Anthropic’s guidance suggests asking the model to extract word-for-word quotes first and base its analysis on them. Applied to email, that means every decision must come with the sender, the date and a quote you can check, and anything unclear is listed as open rather than guessed.

Before you start
- An email thread copied oldest first with sender names and dates
- A few minutes to remove private details and signatures
- Your own role in the thread

Prepare the thread oldest to newest
Copy the messages in time order and label each with sender and date. Delete signatures, disclaimers and quoted repeats. Replace private details if the content is sensitive. Tell the assistant who you are, so it can work out what is waiting on you.
Check your result
The thread is in order with sender and date on every message and no repeated quotes.
Ask for decisions, open items and waiting-on, each with a quote
Request four lists: decisions made, open questions, deadlines and who is waiting on whom. Require each item to include the sender, the date and an exact quote. Items without support go under “unclear”. Then ask for a draft of the single reply you need to send.
Below is an email thread in order. I am [your name/role]. Produce: 1) Decisions made (who, date, exact quote), 2) Open questions (who asked, date, quote), 3) Deadlines (date, who), 4) Who is waiting on whom, 5) Anything unclear. Use only the thread; do not infer decisions. Then draft the one reply I most need to send, under 120 words, with placeholders for facts not in the thread.
Thread:
[paste]Example / expected result
Illustrative example; not a recorded model result.
“Decision (Priya, 3 Oct): ‘We will ship on the 14th.’” Unclear: “Nobody confirmed who updates the website.”
Check your result
Each item has a sender, a date and a quote, and unsupported items sit under “unclear”.
Verify the quotes before you rely on them
Search the original thread for each quoted decision and deadline. Check dates and numbers, and read the last two messages yourself, because the newest ones often change earlier decisions. Edit the draft reply and send it yourself.
Check your result
Every decision and deadline matches the thread, and the reply is edited by you.
When it goes wrong
Models can misattribute who said what, so check names. Threads that mix topics may need separate summaries. Do not paste confidential threads into tools you have not checked. Never send the draft without reading it.
Make it your own
Run a real thread of at least ten messages through the prompt, check three quotes and note any decision the assistant listed that was not actually made.
