How I use Claude Code for real engineering

Matt Pocock demonstrates how he uses Claude Code to add a CLI command to an internal CLI for his AI Hero courses. He emphasizes the importance of creating a plan first, using Claude Code's plan mode to explore the codebase and clarify requirements through multi-step forms. Pocock customizes his rules file to ensure concise interactions and questions, storing unresolved questions for later. He breaks down the implementation into a multi-phase plan to manage the context window, using GitHub issues to preserve the plan across different context windows. Pocock also shares tips such as being concise in memory files, producing unresolved questions, and using the GitHub CLI to create issues for sharing context.
