Bug Fixes and Stability Improvements

Claude Code 2.1.70 resolves critical issues affecting API compatibility and model behavior:

• Third-party gateway support: Fixed API 400 errors when using ANTHROPIC_BASE_URL with proxy endpoints — tool search now correctly detects and handles proxy configurations
• Model parameter compatibility: Fixed errors when using custom Bedrock inference profiles or non-standard Claude model identifiers with the effort parameter
• Model response handling: Fixed empty model responses after ToolSearch by correcting system-prompt-style tag rendering in tool schemas
• Voice mode reliability: Resolved Windows native binary voice failures ("native audio module could not be loaded") and push-to-talk activation issues

Developer Experience Enhancements

VS Code integration now includes native MCP server management accessible via the /mcp command, allowing developers to enable/disable servers, reconnect, and manage OAuth authentication without terminal access. A new activity bar icon lists all Claude Code sessions as full editors.

Additional improvements include better error messages for microphone silence detection, reduced prompt re-rendering (~74%), and faster compaction by preserving images for prompt cache reuse. The Remote Control /poll rate has been optimized from 1–2s to once per 10 minutes, cutting server load by approximately 300×.

Platform-Specific Fixes

• Windows/WSL: Clipboard now correctly handles non-ASCII text (CJK, emoji) using PowerShell
• Git integration: /security-review command now works on older Git versions; /color command now supports reset operations
• Marketplace: Plugin installation errors are resolved through auto-refresh on startup

The release also introduces markdown document view for plans in VS Code with comment feedback support and improved workspace management for Remote Control sessions.
