Claude-Code v2.1.80 adds rate limit monitoring, plugin improvements, and memory optimizations

What's new in Claude-Code v2.1.80

Claude-Code v2.1.80 includes several practical improvements for developers using AI coding agents, focusing on monitoring, plugin management, and performance optimizations.

Key features and improvements

• Rate limit monitoring: Added rate_limits field to statusline scripts for displaying Claude.ai rate limit usage with 5-hour and 7-day windows showing used_percentage and resets_at
• Plugin marketplace source: Added source: 'settings' option to declare plugin entries inline in settings.json
• CLI tool detection: Added CLI tool usage detection to plugin tips, complementing existing file pattern matching
• Effort level control: Added effort frontmatter support for skills and slash commands to override the model effort level when invoked
• MCP server channels: Added --channels flag (research preview) allowing MCP servers to push messages into your session
• Memory optimization: Reduced memory usage on startup in large repositories, saving approximately 80 MB on repositories with 250,000 files

Bug fixes

• Fixed --resume dropping parallel tool results - sessions with parallel tool calls now restore all tool_use/tool_result pairs instead of showing [Tool result missing] placeholders
• Fixed voice mode WebSocket failures caused by Cloudflare bot detection on non-browser TLS fingerprints
• Fixed 400 errors when using fine-grained tool streaming through API proxies, Bedrock, or Vertex
• Fixed /remote-control appearing for gateway and third-party provider deployments where it cannot function
• Fixed /sandbox tab switching not responding to Tab or arrow keys
• Fixed managed settings (enabledPlugins, permissions.defaultMode, policy-set env vars) not being applied at startup when remote-settings.json was cached from a prior session

UI improvements

• Improved responsiveness of @ file autocomplete in large git repositories
• Improved /effort to show what auto currently resolves to, matching the status bar indicator
• Improved /permissions - Tab and arrow keys now switch tabs from within a list
• Improved background tasks panel - left arrow now closes from the list view
• Simplified plugin install tips to use a single /plugin install command instead of a two-step flow
