A user on Reddit's r/ClaudeAI has identified a significant issue with how Anthropic's Claude AI handles nested CLAUDE.md files, particularly in auto mode. The problem arises because Claude's default behavior, especially after a recent update (v2.1.229), prioritizes using Bash commands for file operations like reading and editing. This preference for Bash tools bypasses the mechanism that loads nested CLAUDE.md files, leading to custom rules and configurations being ignored in a majority of sessions. The user's analysis shows a drastic drop in nested file loading when the 'Bash-first' instruction is active, impacting agent behavior and adherence to user-defined rules. AI
IMPACT This issue may cause Claude AI agents to ignore custom rules and configurations, potentially leading to unexpected behavior or failure to adhere to user-defined constraints.
