Full changelog

Happy to share the first substantial release in a while.

Key features:

  • /goal for Codex-like auto-self-prompting towards a well-defined objective, early testing shows this approach is very useful
  • /btw for Claude-Code style one-off Q&A while the agent is running, without disrupting main context
  • Agent will now highlight code chunks in the Review Pane it wants you to focus on, further aiding in the transition to fully autonomous agents
  • Agent status in sidebar now generated from small model at pre-defined intervals, so they're more consistently up-to-date

Honorable mentions:

  • Orchestrator restored in part as /orchestrate built-in skill
  • /truncate removed due to dubious value
  • SSH workspace spawn times improved to ~2x RTT
