Turn a long discussion thread into a short reply draft with decisions and open questions.

Copy this prompt

Summarize this discussion thread and draft a short reply. Thread: [PASTE THREAD]. Output: 1) decisions already made, 2) questions still open, and 3) a draft reply under 120 words that confirms the decisions and asks only the open questions. Do not invent decisions that are not in the thread, and mark anything unclear as unclear.

How to use it

Read the last three messages first to find the latest decision, then check the earlier messages for context.

Replace every bracketed placeholder, such as [TOPIC], with your own details before running the prompt. Check facts, numbers, prices, and names in the output before you publish or send it.

Get a better result

• Be specific: one task, one audience, one desired outcome.
• Add one real example or constraint instead of leaving every field generic.
• If the output is too long, ask for a shorter version rather than starting over.
• If the output is too generic, ask it to use your example and cut anything that does not help the reader act.
