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.

Transcript

Your own prompts now render as markdown in the transcript, so lists and code blocks show up formatted.

Feature flag
tengu_turtle_carbon Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

Read once, for one account on one subscription tier, against v2.1.234. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A plain-text user message is now run through the markdown renderer in a new prompt mode instead of being printed raw, so lists, headings and code blocks in what you typed show up formatted. It applies in both the brief and the full transcript layouts.

Details
  • Only for plain-string messages that are not still queued and are at most 4000 characters.
  • Prompt mode renders block structure but skips the inline link and issue-reference rewriting that assistant output gets.
  • Messages containing "ultrathink" are excluded when tengu_turtle_carbon is on; that gate falls back to on.
Evidence

promptMode: !0

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