It controls debug file output for the Agent SDK. Claude Code now reads it directly from the live process environment and interprets the value as on or off, instead of reading it from a copy saved earlier.\n\n**Why**\n\nA value set after startup is now seen, and the variable is read as a switch rather than simply checked for being present."}
