Your CLAUDE.md File Is Getting Too Long. Here's What the Research Says.

In this video I break down exactly why this happens, what the research found actually fixes it, and how to use Claude Code's own features (path-scoped rules, skills, hooks, block-level comments) to keep the file small and the agent reliable. What you'll learn: → Why CLAUDE.md files grow and almost never shrink → "Catastrophic remembering" — the paper's name for the underlying problem → Why block-level comments get stripped from context (and why that matters) → What actually belongs in CLAUDE.md
