Agency AI Coordination Playbook
Coordination practices for agencies running AI agent teams that manage client advertising, call centers, project delivery, and sales pipelines. Battle-tested patterns from a 25-agent production deployment.
Communication
Agent Message Bus
Direct agent-to-agent communication via structured inbox files. Each agent has an inbox at a known path. Messages are typed: REQUEST, INFORM, PROPOSAL, RESPONSE, CHALLENGE. No human in the loop for inter-agent coordination.
What goes wrong without this
Every agent-to-agent handoff requires David to be in the middle. The sales agent finds a churn risk but cannot tell the retention agent directly. It sits in a report until David reads it 3 days later. The client has already left.
Slack Tiered Scanning
Not all Slack channels are equally important. Tier 1 channels (high-signal) are always scanned. Tier 2 channels are scanned with relevance filtering. Tier 3 channels are never scanned. This prevents the briefing from drowning in noise.
What goes wrong without this
The morning briefing includes 200 Slack messages from 40 channels. Most are irrelevant. David stops reading briefings because the signal-to-noise ratio is too low.
