Claude Code v2.1.193: New Shell Classification, Telemetry, and Fixes
Anthropic just shipped Claude Code v2.1.193 with a handful of quality-of-life improvements, telemetry changes, and bug fixes. Here's what you need to know.
New Settings & Telemetry
The big addition is autoMode.classifyAllShell — when enabled, every Bash/PowerShell command goes through the auto-mode classifier, not just arbitrary-code-execution patterns. This gives you finer control over shell safety.
On the telemetry side, there's a new OpenTelemetry log event: claude_code.assistant_response. It includes the model's response text, but is redacted by default. Respects OTEL_LOG_USER_PROMPTS unless you explicitly set OTEL_LOG_ASSISTANT_RESPONSES=1. To keep prompts-only, set OTEL_LOG_ASSISTANT_RESPONSES=0.
Bash Mode & MCP Improvements
Bash mode (!) now has live file path autocomplete — handy for quick commands. MCP servers that need authentication get a startup notice pointing you to /mcp. Also, the headersHelper auth helper now automatically re-runs and reconnects when a tool call returns 401 or 403.
Background Agents & Memory Management
Idle background shell commands are now automatically reaped under memory pressure. Disable with CLAUDE_CODE_DISABLE_BG_SHELL_PRESSURE_REAP=1. Background agents no longer tell Claude to "end your response" — it can keep working on other tasks while the agent runs.
Fixed: pinned background agents were being re-prompted to "Continue from where you left off" after every auto-update. Also fixed a phantom "general-purpose (resumed)" subagent spawning when backgrounding the main turn.
Other Fixes
/model and other client-data-gated UIs no longer show stale/empty state immediately after /login. Backgrounding (←←) no longer spuriously cancels with "N background tasks would be abandoned" when all tasks carry over. Agent panel now shows sibling agents when viewing a subagent. Plugin auto-rename now follows marketplace renames maps automatically. /add-dir message improved when the directory is already a working directory.
