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.

Background-exit prompt says artifact comment monitors keep running

You'll notice
Useful2 Signal2
Artifacts

Backgrounding no longer claims artifact comment monitors will stop; it says they keep auto-replying here.

Feature flag
tengu_bg_leftarrow_inprocess Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.233: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.233. It isn't a statement about your account. What a flag value here can and cannot tell you

What

Pressing left arrow to send work to the background no longer lists artifact comment monitors among the things that will be stopped. They are counted separately and shown as a line saying they keep auto-replying from this terminal.

Details
  • Behind the tengu_bg_leftarrow_inprocess gate, which falls back to on when the server has no value.
Evidence

tengu_bg_leftarrow_inprocess

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