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.

Autocompact Thrashing Detection

What

The autocompact circuit breaker now uses a fixed threshold of 3 consecutive rapid refills (rather than a configurable parameter embedded in the message), and the error message is now more actionable.

Details
  • New message: "Autocompact is thrashing: the context refilled to the limit within 3 turns of the previous compact, 3 times in a row. A file being read or a tool output is likely too large for the context window. Try reading in smaller chunks, or use /clear to start fresh."
  • Previous message was split across multiple string fragments; it's now a single constant.
Evidence

New constant (search for "Autocompact is thrashing: the context refilled to the limit within 3 turns")

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