Big Michael in a channel

Big Michael — channel agent

Big Michael is the name of the agent embedded in Teams and Slack. He is a thin command dispatcher on top of BigLaw's orchestrator — not a separate system.

Commands (all prefixed @BigMichael):

• status [matter] — matter health score + active tasks + top risks
• briefing [client] — full hub-and-spoke client intelligence briefing (all systems)
• search [query] — semantic search across the knowledge store
• task [description] — submit a new roundtable task
• run [template-id] — run a named workflow template
• help — list available commands

Environment variables:

# Teams
TEAMS_WEBHOOK_SECRET=…           # HMAC-SHA256 signing token from Outgoing Webhook setup
TEAMS_INCOMING_WEBHOOK_URL=…     # default channel to post async results + proactive notifications
TEAMS_MATTER_WEBHOOKS='{"M-001":"https://…","M-002":"https://…"}'  # per-matter overrides

# Slack
SLACK_BOT_TOKEN=…                # Bot User OAuth Token (xoxb-…)
SLACK_SIGNING_SECRET=…           # App signing secret for HMAC verification
SLACK_DEFAULT_CHANNEL=…          # fallback channel ID for notifications
SLACK_MATTER_CHANNELS='{"M-001":"C0123ABCD"}'  # per-matter channel map

Proactive notifications — when any matter task completes, Big Michael automatically posts to the linked channel (Teams Incoming Webhook or Slack channel). Wire up at startup with attachTeamsTaskNotifier(orch) and attachSlackTaskNotifier(orch) — already done in src/mcp/server.ts.

Client intelligence briefing — launched by @BigMichael briefing [client]. Spawns 10 parallel spokes (12 s timeout each via Promise.allSettled):
