Codex SDK

Bring the power of the best coding agent to your application.

Installation

npm install @jojoyo/codex-sdk

Usage

Call startThread() and run() to start a thead with Codex.

import { Codex } from "@jojoyo/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,
});
