Claude Code hooks miss file edits in testing

A recent test revealed that Anthropic's Claude Code, when integrated with specific hooks, only recognized a portion of file changes made during its operations. While a 'Stop' hook using `git status` successfully identified all seven file modifications, a 'PostToolUse' hook configured with an 'Edit|MultiEdit|Write' matcher only detected three of these changes. This discrepancy highlights potential limitations in how Claude Code's hooks process edits, particularly when direct bash commands bypass the standard matching mechanisms. AI

IMPACT Highlights potential limitations in how AI code assistants process file changes, impacting developer workflows.
