OpenAI Agents SDK Makes Sandboxes A First-Class Boundary

Intro

OpenAI’s Agents SDK update is a practical reminder that production agents need explicit workspaces, isolated compute, durable state, and credential boundaries.

Takeaways

  • OpenAI says the Agents SDK now includes a model-native harness with configurable memory, sandbox-aware orchestration, Codex-like filesystem tools, MCP tool use, skills, AGENTS.md…
  • One script passes a folder path.
  • The harness owns the agent loop: instructions, memory, tool orchestration, resumable state, and coordination across files and tools.
  • The next important step is whether this workspace-manifest idea becomes portable across agent stacks.
