What is PostToolUse?
The PostToolUse hook is a reactive lifecycle event that triggers immediately after a tool (like Bash, Write, Edit, or a custom MCP tool) completes its execution. While the PreToolUse hook acts as a guard to block actions, the PostToolUse hook is designed for automation, cleanup, and quality control—ensuring that every action Claude takes adheres to your project's standards.
