Cursor 2.0 Changed How I Work
Cursor 2.0 dropped last week, and unlike most recent AI updates, it's actually changed how I work. Two features in particular: Cursor's new Composer model that's 10-50x faster than any other coding model, and parallel agents that finally make running multiple autonomous builds practical. I'll show you Composer building and...

Claude Code vs. Cursor vs. Codex: Cloud Agents Showdown
Cloud-based coding agents from Claude Code on the Web, Cursor Cloud Agents, and Codex all promise the same thing: kick off a task, walk away, and come back to a completed pull request. But do they actually deliver? And more importantly, which one fits into your real-world development workflow?

Comparing Multiple Agents' Work with Git Worktrees & Cursor
I demonstrate my workflow for running multiple AI coding agents (Claude Sonnet 4.5 and Cursor's Composer 1) in parallel on the same feature, then comparing their work to choose the best implementation. The focus is on solving the practical challenges of reviewing agent work in git worktrees by using a branch-based approach that makes testing, debugging, and merging much more manageable.

3 New Features in Claude Code 2.0 I use DAILY
Claude Code 2.0 dropped with Sonnet 4.5, a VS Code extension, and new features. But I've been testing these updates in production for weeks to see what's actually useful for professional developers—not just demos. In this video, I share my honest impressions of what matters for building real products. I'll...
Is Codex CLI Worth The Switch (from Claude Code)?
I've been a daily Claude Code user for most of this year but I wanted to give Codex CLI a look, since OpenAI has been making an obvious effort to win back developers.
Best Practices for Managing and Customizing Agent OS Standards
In this video, I share a best practice for managing and customizing your standards in AgentOS, which simplifies the process of updating to the latest version (it was 2.0.5 at the time of this recording). I demonstrate how I commit my base installation to a private GitHub repo for easy...

Finding FLOW with AI Coding Agents
Remember what FLOW used to feel like? Hours would disappear. It felt amazing—that perfect flow state where you're crafting software with your hands. Well I'm noticing a new flow emerging when I'm building products using AI. I'm finding that this new rhythm of development has a repeating 3-step cycle.
Cursor Keyboard Shortcuts for POWER Users
As professionals, we have to master our tools. My daily driver for coding and building with AI? Cursor (a fork of VS Code). So I'm sharing all most frequently used Cursor keyboard shortcuts, how I've customized them and how you can customize your shortcuts in Cursor (or VS Code).
