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.

Collapsed agent messages show a one-line preview

Subagents

A collapsed subagent message now previews its first line instead of just showing a count.

ctrl+o
What

A collapsed message from a subagent now renders a truncated preview of the body after the name, so you see Message from @name: … (ctrl+o to expand) instead of just a count.

Details
  • The preview is italic and appended after the message count.
  • The related full "Message from …" renderer now chooses between collapsed and full output based on verbose mode as well as transcript mode, so --verbose expands these too.
