100+ OpenAI Codex CLI Tricks & Tips (from beginner to advanced)
The Complete Guide for Creative Professionals . Codex-CLI version 0.29 (September 2025) - [update - 0.39]
Last week's updates fundamentally shifted which tools actually work
While most developers were perfecting their Claude Code workflows, Codex CLI quietly evolved into something different. Not through marketing. Not through hype. Through actual capabilities that weren't there before.
The evidence is clear: developers using these specific Codex CLI techniques are completing projects in hours that take others days. Not because they're better programmers. Because they know new commands and workflows that transform how the tool operates.
Here's what makes this significant: these aren't advanced techniques requiring years of experience. Beginners are implementing them in minutes. Senior developers are discovering shortcuts they should have known years ago.
What follows is the complete collection, every command, workflow, and configuration that matters. From basic setup that takes 30 seconds to advanced orchestration that changes how you build software. Each one tested, documented, and actively used by developers shipping production code today.
The shift already happened. Claude Code's advantages evaporated with the latest updates. Codex CLI emerged as the tool that actually delivers.
Most developers will figure this out eventually.
