OpenAI Agents SDK

Patterns this framework supports natively

• ★★ Tool Use — Let the LLM produce typed calls against an external toolkit instead of producing free-form text the surrounding system has to parse.
• ★★ ReAct — Interleave a single thought, a single tool call, and a single observation per step so the agent reasons over fresh evidence.
• ★ Handoff — Transfer the active conversation from one agent to another, carrying context across the switch.
• ★★ Structured Output — Constrain the model's output to conform to a JSON Schema (or similar typed shape).
• ★★ Step Budget — Cap the number of tool calls or loop iterations the agent is allowed within a single request.
• ★★ Input/Output Guardrails — Validate inputs before they reach the model and outputs before they reach the user.
• ★★ Decision Log — Persist the agent's reasoning trace alongside its actions so post-hoc review can explain why.
