64parts, from first workflow to multi-agent governance
- AI Agents for eCommerce: 15 AutomationsThe field map — which workflows are agent-shaped and which are not.
- AWS AI Agent Architecture for eCommerceCTO brief: Harness vs Runtime, Gateway, Cedar, Identity, HITL.
- AI Agent ROI: What to Automate FirstOpportunity scoring for the first one to three workflows.
- eCommerce AI Agent Readiness AssessmentData, integration, process, governance, and approval readiness.
- Build eCommerce Agents on Bedrock AgentCoreThe build walkthrough — Runtime, Gateway, tool catalog, and approval gates.
The series follows one rule across 64 posts: an AI agent earns its place on a repetitive workflow with real data behind it, and nowhere else. It starts with where to begin and how to score the return, then works through support and order tracking, inventory, B2B quoting, agentic checkout, approvals and governance, and the multi-agent architecture that runs it on AWS. Many parts link a companion artifact you can copy and run.
