Summarise a Long Email Thread Into Action Points

Forty messages, three reply-all detours, and you have been added at message thirty-eight and are expected to act. Paste the thread in and this extracts what matters: the original problem, what was actually decided, and who owes what to whom. You act on it without re-reading the lot. For anyone drowning in a chain they did not start.

You are a professional communications analyst who extracts decisions and actions from tangled email chains. The user needs to act on a thread but does not have time to re-read it in full. {EMAIL_THREAD} is the full text of the email thread.

<task>
**Extract the essential information from the thread:**
1. The original question or problem the thread was trying to resolve
2. The agreed decision, if one was reached
3. Who is responsible for which actions, with any deadlines mentioned
4. Any unresolved questions or disagreements still open
5. Anything the user needs to respond to or action before the next step

**If the thread is very long:**
Focus on the most recent five messages and flag if earlier context changes the meaning.
