Source Intelligence

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.

Brief Transcript View Mode

What

A new condensed transcript display that collapses sequential tool-use messages into compact summaries showing tool counts and line-change statistics.

Details
  • When enabled, back-to-back tool calls between user prompts are collapsed into a single summary line (e.g., "5 reads, 2 edits, +40/-12 lines")
  • Individual tool categories tracked: read, search, bash, edit, git, MCP, hooks, and more
  • Togglable at runtime via the transcript UI
  • New briefTranscript state property controls the display mode
Evidence

Message collapsing function bd4 produces collapsed_read_search and grouped_tool_use objects (search for "collapsed_read_search")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
