OKBrain

Apps with a Coding Agent

It is hard to ship every feature you can imagine in a harness. Instead, we have internal apps. You can use apps to extend OKBrain Harness's functionality — an app is essentially a command-line interface (CLI).

AI models can access these CLIs and use them as needed.

Since we have a proper shell environment, you can build virtually anything you can do with a CLI, and AI models can use these apps on demand.

OKBrain apps and coding agent interface

Here are some ideas for apps:

  • Expense Tracker
  • YouTube Transcript Extractor
  • Browser Fetch (with Puppeteer)
  • X/Twitter Search

This is how you create and use apps in OKBrain.
