Changelog

What's changed

  • Fixed agent teammate sessions in tmux to send and receive messages
  • Fixed warnings about agent teams not being available on your current plan
  • Added TeammateIdle and TaskCompleted hook events for multi-agent workflows
  • Added support for restricting which sub-agents can be spawned via Task(agent_type) syntax in agent "tools" frontmatter
  • Added memory frontmatter field support for agents, enabling persistent memory with user, project, or local scope
  • Added plugin name to skill descriptions and /skills menu for better discoverability
  • Fixed an issue where submitting a new message while the model was in extended thinking would interrupt the thinking phase
  • Fixed an API error that could occur when aborting mid-stream, where whitespace text combined with a thinking block would bypass normalization and produce an invalid request

  • Fixed /resume session picker showing raw XML markup instead of clean titles for sessions started with slash commands
  • Improved error messages for API connection failures — now shows specific cause (e.g., ECONNREFUSED, SSL errors) instead of generic "Connection error"
  • Errors from invalid managed settings are now surfaced
  • VSCode: Added support for remote sessions, allowing OAuth users to browse and resume sessions from claude.ai
  • VSCode: Added git branch and message count to the session picker, with support for searching by branch name
  • VSCode: Fixed scroll-to-bottom under-scrolling on initial session load and session switch
