In this masterclass I break down ten Claude Code “hacks” I pulled from Boris Churnney (the guy who literally created Claude Code) and translate his borderline-biblical X threads into stuff you can actually use inside your IDE. The big theme is simple: stop coding like it’s 2019. Parallelize everything, plan before you build, and make your agent smarter over time instead of re-explaining yourself every single project. First, I show Git worktrees: multiple Claude Code instances on separate branches/folders so you can build features in parallel (I demo spinning up about/contact/services pages at the same time, then merging them back into main). Then we hit plan mode—because one good plan saves hours of implementation and revision—plus the real power move: iterate your claude.md (your “system prompt”) so mistakes don’t repeat. From there I cover skills (and committing them to a shared repo), better prompts (“scrap this and implement the elegant solution”), Ghostty for running a ridiculous number of panes without melting your machine, and sub-agents (yes, I used to hate them) for clean, objective code reviews. Finally, I show output styles like Explanatory/Learning and how to generate quick ASCII diagrams so you actually understand what Claude just did. Net-net: you move 3–5x faster, your repos stay cleaner, and you ship real systems that make real money.
