Tools-First Agent Architecture: Shipping End-to-End Outcomes
A chat interface is not a workflow.
Business outcomes happen when agents can act: update CRM, prepare reports, send emails, follow SOPs.

- separate conversation from execution
- define strict I/O contracts
- keep explicit process state
- verify before risky actions
- design graceful degradation
Tools-first is how “smart chat” becomes a production worker.
