Unclear What the extra timer is for is not settled.
What
When an MCP tool call (a request to an outside tool you connected) finishes, the check that watches for the call going idle now clears one more timer than before. The idle timeout itself and its error message, which points to CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT, are unchanged.
Why
This is small housekeeping that stops a timer from being left behind after a call; nothing visible changes.
