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.

A failed exit-time transcript write now aborts the remaining writes

Under the hood
Useful2 Signal2
Sessions

A failed final transcript write now stops rather than continuing through other storage backends.

What

If the final line owed to the transcript at exit fails to append through the storage backend, the session store records the error and stops, rather than logging it and continuing through the other storage providers.

Details
  • The logged message text is unchanged.
Evidence

Exit line owed to the transcript was not appended through the storage backend

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