Codex SDK
Bring the power of the best coding agent to your application.
Installation
npm install @openai/codex-sdk
Usage
Call startThread() and run() to start a thead with Codex.
import { Codex } from "@openai/codex-sdk";
const codex = new Codex();
const thread = codex.startThread();
const result = await thread.run("Diagnose the test failure and propose a fix");
console.log(result);
You can call run() again to continue the same thread.
const result = await thread.run("Implement the fix");
console.log(result);
Streaming
The await run() method completes when a thread turn is complete and agent is prepared the final response.
You can thread items while they are being produced by calling await runStreamed().
const result = thread.runStreamed("Diagnose the test failure and propose a fix");
Resuming a thread
If you don't have the original Thread instance to continue the thread, you can resume a thread by calling resumeThread() and providing the thread.
const threadId = "...";
const thread = codex.resumeThread(threadId);
const result = await thread.run("Implement the fix");
console.log(result);
Working directory
By default, Codex will run in the current working directory. You can change the working directory by passing the workingDirectory option to the when creating a thread.
const thread = codex.startThread({
workingDirectory: "/path/to/working/directory",
});
To avoid unrecoverable errors, Codex requires the working directory to be a git repository. You can skip the git repository check by passing the skipGitRepoCheck option to the when creating a thread.
const thread = codex.startThread({
skipGitRepoCheck: true,
});
