Claude Code can now programmatically scroll a specific message into view in the transcript

What

  • The transcript-rendering component now passes a new revealRef value through to the virtualized message list, alongside the existing search-related props.
  • The transcript's virtualization hook exposes a reveal(index, block) method that finds a message by id, scrolls it into view with a given alignment, and retries if the target row hasn't mounted yet.
  • The full-screen transcript component forwards this new reveal prop into the message-list renderer alongside existing scroll/search state.

Why

This adds the plumbing needed to jump straight to a specific message in a long transcript, rather than requiring manual scrolling or search.
