Claude Code 2.1.80

This release enhances your experience with new features such as real-time AI rate limit usage visible in your statusline and experimental `--channels` support. Plugin management is also streamlined with inline settings and better discovery. Key reliability fixes include the complete restoration of parallel tool results when resuming sessions, voice mode WebSocket failures, and consistent managed settings application. Developers will appreciate fixes for 400 errors during fine-grained tool streaming. Further improvements offer reduced memory usage, especially for large repositories, faster file autocompletion, and simplified plugin installation for a more robust and responsive environment.

Added

  • Added `rate_limits` field to statusline scripts for displaying Claude.ai rate limit usage (5-hour and 7-day windows with `used_percentage` and `resets_at`)
  • Added `source: 'settings'` plugin marketplace source — declare plugin entries inline in settings.json
  • Added CLI tool usage detection to plugin tips, in addition to file pattern matching
  • Added `effort` frontmatter support for skills and slash commands to override the model effort level when invoked
  • Added `--channels` (research preview) — allow MCP servers to push messages into your session

Improved

  • 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

Changed

  • Simplified plugin install tips to use a single `/plugin install` command instead of a two-step flow
  • Reduced memory usage on startup in large repositories (~80 MB saved on 250k-file repos)

Fixed

  • 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
