The Claude Code development team has released version 2.1.145, packed with significant improvements for power users and developers working with Claude agents and plugins. This release focuses on enhanced scriptability, better user experience, and important security fixes.

What’s New

Enhanced Agent Management

  • JSON Agent Listing: The new claude agents --json command enables seamless integration with external tools like tmux-resurrect, status bars, and session pickers by outputting live Claude sessions in JSON format
  • Improved Terminal Titles: Agent terminal tabs now display awaiting-input counts, making it easy to identify when agents need attention while alt-tabbing
  • Better Telemetry: Added agent_id and parent_agent_id attributes to OTEL spans with fixed trace parenting for better debugging

Plugin Discovery Enhancements

  • Comprehensive Plugin Preview: The /plugin Discover and Browse screens now display complete plugin information including commands, agents, skills, hooks, and MCP/LSP servers before installation
  • Improved Validation: claude plugin validate now properly flags incorrect skills: entries and suggests the correct parent directory

User Experience Improvements

  • Mouse Support: Slash command and @-mention suggestions now support mouse hover and click in fullscreen mode
  • Voice Integration: Fixed push-to-talk functionality in agent view reply panes
  • Better Error Messages: MCP prompt slash commands now show clear, actionable error messages when required arguments are missing

Security & Stability Fixes

  • Permission Security: Fixed a critical bypass where bare variable assignments to non-allowlisted environment variables in Bash commands were auto-approved
  • Cross-Platform Compatibility: Resolved Windows PowerShell 5.1 issues with cross-project resume hints
  • GitHub Integration: Fixed PR badge updates and /review command compatibility with modern GitHub GraphQL API

Developer Experience

  • Enhanced Context: Status line JSON now includes GitHub repo and PR information when detected
  • Improved Read Tool: Better handling of large files with truncation and “PARTIAL view” notices instead of hard errors
  • Bug Fixes: Resolved issues with task list ordering, spinner display, and Agent Teams with non-ASCII names
