Claude Code v2.1.193 Release Notes

Claude Code version 2.1.193 introduces several enhancements to auto-mode classification, telemetry logging, and background agent management. This update also includes fixes for UI state issues, authentication handling in MCP servers, and various backgrounding bugs.

• Added `autoMode.classifyAllShell` setting to route all Bash/PowerShell commands through the auto-mode classifier.
• Introduced `claude_code.assistant_response` OpenTelemetry log event, controllable via `OTEL_LOG_ASSISTANT_RESPONSES`.
• Implemented live file path autocomplete in bash mode and automatic memory-pressure reaping for idle background shells.
• Fixed issues with stale UI state after login, spurious background task cancellation, and phantom subagents during main turn backgrounding.
• Improved MCP `headersHelper` to automatically reconnect on 401/403 errors and enabled automatic plugin auto-rename following marketplace maps.

These changes enhance security granularity for shell command classification, provide deeper observability into model responses, and improve the stability of long-running background agents.
