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 writer knows when writes are still outstanding

Under the hood
Useful2 Signal2
Sessions

The transcript writer can now report whether writes are still pending, so nothing reads a half-written file.

What

The component that writes your session transcript now counts writes in progress and exposes a check for whether any remain, so other code can wait rather than acting on a partly written file.

Details
  • Separate counters track queued flushes and direct appends, each decremented in a finally block so a failed write does not leave the count stuck.
Evidence

appendInFlight()

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