Step-by-Step: Build Your First Agent with OpenAI’s Agent Builder

Agent Builder provides a visual, guided canvas for composing multi-step agent workflows without heavy engineering. It lets you prototype logic with drag-and-drop nodes, attach tools and data sources, add safety guardrails, and test behavior before deploying to users.:contentReference[oaicite:8]{index=8}

1. Sign in and open Agent Builder: Log in to the OpenAI Platform and choose Agents → Agent Builder to start a new workflow. The interface launches a canvas where you can add nodes for reasoning, tool calls, and branching logic.:contentReference[oaicite:9]{index=9}
2. Sketch the agent goal: Define a single clear task for your agent (for example: schedule meetings, summarize documents, or run a data lookup). Keep the first prototype small so you can iterate quickly.:contentReference[oaicite:10]{index=10}
3. Compose nodes and connect tools: Drag nodes for prompts, conditionals, and tool integrations (APIs, databases, webhooks). Connect the flow so the agent can call tools when needed and return results to users.:contentReference[oaicite:11]{index=11}
4. Set memory and safety rules: Decide what the agent should remember and enforce guardrails to prevent undesired actions. Use versioning so you can compare iterations safely.:contentReference[oaicite:12]{index=12}
5. Preview and test locally: Use the built-in preview and testing tools to step through example runs, confirm tool behavior, and refine prompts and branching logic. Prototyping small scenarios catches logic errors early.:contentReference[oaicite:13]{index=13}
6. Deploy and monitor: Publish once tests look good, then monitor real usage, collect feedback, and iterate. Instrument the agent with logs and evaluation checks to ensure reliability in production.:contentReference[oaicite:14]{index=14}

Agent Builder is part of a broader agent developer stack that makes it easier to go from prototype to production. Start with a minimal working agent, add tools and guardrails as you validate outcomes, and use automated evaluations to keep quality high as usage grows.:contentReference[oaicite:15]{index=15}
