What happened
This article walks through five real examples of using computer and browser use features in Codex, including app QA, LinkedIn management, and online shopping. It also shares an 'under-prompting' technique intended to make frontier models work harder. The focus is practical demonstration rather than theory.
Why it matters
For Malaysian developers, vibe coders, and AI agent users, hands-on examples of browser/computer use in Codex are directly applicable to automating repetitive workflows like QA testing, social media management, and research. The under-prompting trick is a useful prompt engineering tactic worth testing in local projects and SaaS operations.
Discussion angle
Which local workflows (QA, admin, research) are realistic candidates for browser/computer use agents today, and where do they still break down in practice?
