Been getting messages asking how I use Codex in my projects. Finally made a video about it!

I break down my entire workflow and share the tips and tricks that make the biggest difference in my daily coding.
Hope it helps 👍

To the right, there’s a screenshot of the OpenAI Codex interface displaying the text 'What should we code next?' with a red arrow pointing to the input box. Above, bold text reads 'TIPS & TRICKS' in purple and pink gradient letters.

If you’re using Windsurf and not adding MCP servers you’re missing out on serious power.

I’ll show you how to add them from the store and manually (including Snyk!)

I asked Claude Sonnet 4.5 to build a secure Node.js note taking app from scratch. The results surprised me!

Watch here 👇

Clarkio wearing a backward black Snyk cap looking surprised, set against a bright purple and blue background. To his right is an editor window titled 'SECURITY_REPORT.md' displaying a Markdown document describing a 'production-ready, security-hardened Node.js notes application.' Above him is the orange starburst logo for Anthropic, and bold gradient text at the bottom reads 'BEST IN THE WORLD?!' in blue and purple letters.

Stop using .env files for your API keys. They’re not safe anymore.

Here’s why and what to do instead 👇

Clarkio with a thoughtful face wearing a backwards Snyk cap, resting his chin on his hand. At the top is a code editor showing .env, package.json, and index.js tabs, with code that logs API_KEY from process.env. To the right is a tweet screenshot that says 'Cursor steals your dev creds,' with a red arrow pointing at it. At the bottom, bold red text reads '.ENV IS BAD' against a purple background.

Spec-driven development + AI = the future? 🤔

I explored Amazon’s new Kiro IDE paired with Claude Sonnet 4 to find out.

Watch and tell me if you’d code like this 👇

Bright thumbnail image featuring a surprised clarkio on the left side, with wide eyes and open mouth. The background is a vibrant mix of purple and pink hues with binary code pattern. Bold text at the top reads 'SPEC DRIVEN DEVELOPMENT' in blue and white. On the right, a UI screenshot shows two options: 'Vibe' and 'Spec,' with the 'Spec' option highlighted, which says 'Plan first, then build. Create requirements and design before coding starts.' A red arrow points to the highlighted option.

I put Replit to the test and was honestly shocked by the outcome. If you care about what AI coding tools can (and can’t) do, you’ll want to see this.

On the right-hand side is text in bold letters "This is crazy!" overlayed on the Replit logo. Above that is a screen shot of the application that was built in the video. On the left-hand side is an image of clarkio smiling. The background is a gradient from purple to blue with circuit lines and 1's and 0's

This has been a fun loop🤪

Agent: Everything is done let me run the app
Terminal: App running
Agent: Perfect! Let me test it with curl
*kills app for curl*
Agent: Let me start the server again and test it
Terminal: App running
Agent: Perfect! Let me test it with curl

Agent mode (preview) is here for GitHub Copilot in VS Code!

In agent mode in Copilot Edits, Copilot can now iterate on its own output, execute terminal commands, and even self-heal from runtime errors.

Try it in VS Code Insiders: https://code.visualstudio.com/updates/v1_97#_agent-mode-experimental

Folks making videos, don't tell your audience to leave a comment/question where you'll reply with your answer and then don't reply to any of them.

Of course, there are some exceptions to this like trolls or hate comments...
