Engineering briefing: Slack + Workspace + Parallel Web

"""
Engineering briefing: Slack + Workspace + Parallel Web
======================================================

Three sources, one agent.

  Slack      what the team is talking about right now
  Workspace  what this repo already knows about it
  Web        fallback context when the repo has no clear match

The main agent does synthesis. Each provider owns its own mess.

Requires:
    OPENAI_API_KEY
    PARALLEL_API_KEY   https://platform.parallel.ai/
    SLACK_BOT_TOKEN    scopes: channels:read, channels:history,
                       users:read, chat:write
    pip install parallel-web
