Team briefing: Slack + Web
==========================

Cross-reference internal Slack discussion with external industry
news to produce a short briefing.

Workflow the agent performs:
  1. Pull recent messages from an engineering Slack channel
     (``query_slack`` → ``get_channel_history``).
  2. For each topic it surfaces, find a current external reference
     (``query_web`` → Parallel search).
  3. Return a briefing tying each internal thread to a supporting
     external source.

The compositional shape — one provider's output informing the next
provider's query — is the payoff of multi-provider. Parallel
"two unrelated questions" is a weaker demo; real workflows chain.

Requires:
    OPENAI_API_KEY
    PARALLEL_API_KEY   (https://platform.parallel.ai/)
    SLACK_BOT_TOKEN    (or SLACK_TOKEN fallback; scopes: channels:read,
                        channels:history, users:read)
    pip install parallel-web

Optional:
    SLACK_USER_TOKEN   (xoxp-) enables search_messages API
