# OpenAI Agents SDK over ACP

> Package a customer-owned OpenAI Agents SDK loop behind Checkfu's ACP v1 harness boundary.

Source: `examples/openai-agents-acp` in the repository. Its README carries the
complete build, digest pinning, adoption, and verification commands.

This is a bring-your-own-harness example, not a second managed Codex path.
The exact Codex recipe in Checkfu's generic Vercel workload remains the sole
curated Codex integration. Use this example when you own an `@openai/agents`
loop and want to package it as an OCI harness.

The example deliberately declares a narrow runtime contract:

* ACP v1 text prompts, one session, and `mcp_delivery: none`;
* the `openai_responses` model wire through Checkfu's injected gateway URL and
  short-lived token;
* process-wide and Runner-level SDK tracing shutdown so that gateway credential
  is not sent to a separate trace exporter;
* cooperative `session/cancel`, with only notification-send-completed optional
  same-session history and no remote delivery claim.

Start with the repository README, run its commit-tier tests, build the exact
locked image, then register it with `--model-wire openai_responses` and
`--mcp-delivery none`. For the protocol floor without any agent SDK, read the
[dependency-free custom ACP example](/examples/custom-acp).
