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.

Claude Code v2.1.229

Backgrounded shell commands note how they ended

You'll notice
Useful3 Signal1
Background Tasks

Background shell output now ends with a line saying it was killed or its exit code.

What

When a shell command you sent to the background finishes, a bracketed line is appended to its captured output saying either that it was killed or what exit code it returned, so the transcript records the outcome rather than just stopping.

Details
  • The marker is written before the existing success/failure telemetry for the background shell.
Evidence

exited with code

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