The 200-Line Rule: Why Your CLAUDE.md Gets Ignored

Teams typically overload their CLAUDE.md files with comprehensive rules, but Claude only reliably processes around 150 distinct instructions—roughly the equivalent of 200 lines. Beyond this threshold, your carefully crafted guidelines become invisible noise, technically present but effectively unread. The real optimization lies in ruthless prioritization: anchor non-negotiables at the file's top where they survive session compression, and route task-specific knowledge to dedicated documentation rather than bloating a single configuration file.
