"""
Channel Summarizer
==================
An agent that reads channel history and produces structured summaries.
Supports follow-up questions in the same thread via session history.
Key concepts:
- ``SlackTools`` with ``enable_get_thread`` and ``enable_search_messages``
lets the agent read Slack data as tool calls.
- ``add_history_to_context=True`` + ``db`` enables follow-up questions
within the same Slack thread — the agent remembers previous exchanges.
- ``num_history_runs=5`` includes the last 5 exchanges for context.
Slack scopes: app_mentions:read, assistant:write, chat:write, im:history,
channels:history, channels:read, search:read, users:read
