DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.224

Worker shutdowns carry a typed reason

Under the hood
Useful2 Signal3
Remote Control

Background worker exits now carry a typed reason such as expired token or epoch conflict.

What

Fatal exits now pass a reason such as session not found, token expired, auth exhausted, or an epoch conflict or stale epoch, instead of terminating with no explanation.

Details
  • The remote bridge maps auth-related reasons to WebSocket close code 4094 and the rest to 4090, so recovery can pick the right path.
