I asked Claude Code to run my tests, merge a PR, and cut a release. It did all of it—no GitHub UI, no manual commands. Just me and a terminal shipping a feature to production. Plan Mode spawned five sub-agents, researched my codebase, asked clarifying questions, then built exactly what I described. Not what I coded. What I described. That's the shift. This isn't a 101 for absolute beginners. If you're already engineering with Cursor, Copilot, or another tool and you've heard the hype—this is for you. Three things will get you to Level 20 with Claude Code faster than anything else, and I'm skipping the 8-feature settings tour to show you exactly what they are. What you'll see in action: - Building a welcome screen feature from PRD to production - Plan Mode spawning multiple sub-agents to research my codebase - The exact moment to use /clear and why context isolation matters - Running tests (including headed E2E so you see the browser go bananas) - Creating a PR, merging it, and cutting a release—all from the terminal - The what vs. how mindset that separates frustration from flow The secret? Stop thinking about code changes. Start thinking about outcomes. Define what you want—not how to build it—and let the planning system figure out the implementation. This shift is why I went from rarely using Plan Mode to using it on almost everything. If you're a Cursor user wondering whether Claude Code is actually different: yes, but not in the way you might expect. It's not just another agent panel. It's a different way of working—one where you become better at defining targets, and the system handles increasingly complex work autonomously. Heads up: I'm running with bypass permissions on in this repo. Be careful with that. Let it ask you before approving actions until you build confidence. Drop a comment if you want me to go deeper on any of these topics. There's a follow-up video coming that covers my full workflow and process—this is just the taste.
