New hook configuration example:

// Configure hooks in settings
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "file_edit|str_replace",
        "hooks": [
          {
            "type": "command",
            "command": "echo 'About to edit a file' | tee -a /tmp/claude.log"
          }
        ]
      }
    ]
  }
}
