Many businesses start agent experiments by pasting an SOP into a prompt and asking the model to follow it. That can be useful for a demo, but it is fragile when the workflow touches customers, refunds, records, contracts or publishing. Google's explanation of ADK 2.0 is direct about the risk: production agents can get stuck in loops, bypass business logic through hallucination, or fail without a clean exception path. Those are operating risks, not copywriting problems. ## What changed in Google ADK 2.0? Google describes ADK 2.0 as moving agent development toward a structured workflow runtime and a task-collaboration model. In business terms, that means separating flexible reasoning from predictable execution. > Implementation note: before an agent touches a live system, describe the workflow as states and transitions: what starts it, what evidence it needs, where it can branch, what can be retried, and what requires approval. ## How does ADK for Go 2.0 make this pattern more concrete? Google's ADK for Go 2.0 announcement makes the workflow pattern more explicit through a graph-based workflow engine. Developers can describe applications as nodes and edges, then use a scheduler to run the graph. The source material highlights routing, fan-out and fan-in, loops, state persistence, pause and resume, retries, timeouts and concurrency controls. Those features matter because real agent work is rarely a single chat turn. ## Where should human review sit in an agent workflow? Human-in-the-loop review is often the control that makes automation deployable. Google's Go 2.0 announcement describes workflow nodes that can pause for human approval, correction or additional information, then resume durably after the response. For SMBs, approval points include refunds, contract changes, ad spend, customer complaints, public posts, compliance-sensitive advice and destructive changes in a business system. ## What should SMBs map before they automate? - Map the current workflow from trigger to final record or customer response. - Mark every fixed step that should run the same way each time. - Mark every judgement step where an LLM can classify, summarise, draft or recommend. - Add approval gates for high-risk decisions and external-facing actions. - Define retry, timeout and escalation rules before the workflow goes live. - Log inputs, decisions, approvals, failures and outcomes so the workflow can be improved. ## How should an SMB start safely? Start with a narrow workflow where the value is visible and the risk is contained. Good first candidates include form triage, support categorisation, quote preparation, content drafting, inbox summaries or internal task routing. RxAI helps businesses turn these ideas into practical systems: scoped workflows, clear permissions, human review, monitoring and a rollout plan that matches the risk of the process.

Google ADK 2.0 is Google's updated Agent Development Kit direction for building production agents with structured workflows, task collaboration and more deterministic control over application flow. ### Why should SMBs care about graph-based agent workflows? Graph-based workflows make the agent process visible and controllable. They help teams define routes, retries, approval points, state and recovery paths before automation touches live business systems. ### Does this mean every AI task needs a complex workflow engine? No. Simple drafting or summarisation tasks may not need one. Workflow design matters when the agent takes multi-step actions, uses tools, handles customer records or affects money, compliance or public communication. ### Where should human approval be added? Add approval before external messages, refunds, contract changes, ad spend, publishing, destructive system changes and any decision where the business would normally require manager review.
