[Release] anthropics/claude-code v2.1.193: v2.1.193

Claude Code v2.1.193 introduces enhanced auto-mode shell command classification, improved OpenTelemetry logging with assistant response tracking, live file path autocomplete in bash mode, and MCP server authentication notifications. The release fixes critical issues with background agent management, session persistence, and UI state handling while improving background task memory management and plugin auto-renaming functionality.

Key Points

• •New `autoMode.classifyAllShell` setting routes all Bash/PowerShell commands through auto-mode classifier for consistent security evaluation
• •OpenTelemetry logging now captures assistant responses with `OTEL_LOG_ASSISTANT_RESPONSES` control; defaults to following prompt logging settings to avoid breaking changes
• •Live file path autocomplete added to bash mode (!) for improved command-line usability
• •MCP servers requiring authentication now trigger startup notices directing users to `/mcp` configuration page
• •Automatic memory-pressure reaping for idle background shell commands prevents resource leaks (disable with `CLAUDE_CODE_DISABLE_BG_SHELL_PRESSURE_REAP=1`)
• •Fixed background agent session persistence issues where agents were re-prompted unnecessarily after auto-updates
• •Fixed backgrounding logic to prevent phantom subagent spawning and spurious task abandonment warnings
• •Improved MCP `headersHelper` authentication with automatic reconnection on 401/403 responses
• •Plugin auto-rename now follows marketplace `renames` maps automatically, updating user settings
• •Fixed UI state issues where client-data-gated components showed stale/empty states after login
