Lesson 60 — Project 4: Collaborative Agent Team

Highlights

What we build

• A five-agent MarketResearchCrew that performs end-to-end competitive intelligence: industry landscape → competitor mapping → data synthesis → strategic recommendations → executive report

• A FastAPI backend with a CrewWebSocketBridge that tunnels synchronous CrewAI step callbacks into async WebSocket streams

• A dark-themed React dashboard with live agent status indicators, a real-time activity feed, and a rendered markdown report viewer

• SQLite WAL persistence for every crew run, surfacing CrewExecutionRecord structs consumed by L61’s MLOps pipeline

• Full integration of L59’s LoguruInteractionTracer wrapping every step_callback event for structured inter-agent communication logs

Connection to L59 (MAS Evaluation & Debugging)

L59 equipped us with LoguruInteractionTracer for structured inter-agent communication capture and MASProfiler for execution timeline analysis. Here those tools move from test harness to production path: every step_callback event fired by the crew is intercepted, logged through the L59 tracer, and forwarded over WebSocket. The AgentCallGraph built in L59 maps directly onto CrewAI’s sequential task chain.

Enables L61 (Introduction to MLOps for Agentic AI)

Every crew run persists a RunTelemetryBundle — a structured record containing the role registry, task artifact chain, execution durations, token counts, and final output. L61’s MLOps pipeline ingests this bundle as its canonical “agentic run” unit. The CrewExecutionRecord schema defined here becomes the version-trackable artifact that MLOps will govern.

Architecture Context

Place in the 90-lesson VAIA path

L60 is the capstone project of the multi-agent systems arc (L46–L60). It synthesizes every pattern from that arc — role specialization (L47), task decomposition (L48), sequential orchestration (L50), tool use (L52), evaluation (L59) — into a production-ready crew. Module 5 then opens at L61 with MLOps, treating this crew as the system under governance.

Module 5 alignment

Module 5 (Enterprise MLOps, L61–L75) requires a fully instrumented agentic system to govern. L60 builds that system. The RunTelemetryBundle is the unit of currency in Module 5 — without it, concepts like model versioning, drift detection, and deployment gates are abstract. This lesson makes them concrete.
