Copilot CLI 1.0.22-0: Agent Limits & Session Fixes

TL;DR

  • Sub-agent depth and concurrency limits prevent runaway agent spawning
  • Session hooks now fire once per session instead of per prompt in interactive mode
  • Plugin agents respect frontmatter model specifications

New

  • Sub-agent depth and concurrency limits — prevents runaway agent spawning that could consume resources or create infinite loops
  • Session resumption warning — alerts you when resuming a session already in use by another CLI or application

Fixed

  • CLI no longer crashes on systems affected by a V8 engine bug in grapheme segmentation
  • sessionStart and sessionEnd hooks fire once per session in interactive mode instead of once per prompt
  • Plugin agents now respect the model specified in their frontmatter

Update with: npm install -g @github/copilot-cli@1.0.22-0
