telegram-summarize

name	telegram-summarize
description	Use when Telegram summaries, unread catch-ups, or recaps are requested.

1. If the chat is unspecified, call list_dialogs and have the user pick the relevant dialog(s).
2. Resolve the time window before fetching history. Prefer explicit windows like today, last 24h, or ISO timestamps.
3. For known chats, prefer cache-backed summaries when the window is broad, old, repeated, or needs to be exhaustive: call sync_chat_cache if the chat is missing/stale, then iterate summarize_chat_history chunk-by-chunk (chunk_index 0..N-1). Summarize each chunk before fetching the next and merge the chunk summaries. Use get_history only for small, recent, one-off windows such as “today” or “last 24h”.
4. Group messages by speaker and sequence so the summary follows the conversation, not isolated quotes.
5. Attribute important decisions or claims to the sender when possible.
6. Produce this output shape unless the user asks otherwise:
   • TL;DR
   • Key decisions
   • Open questions
   • Action items
   • Notable quotes
7. If the user asks to compare multiple chats, keep each chat separate first, then add a cross-chat synthesis section.
