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.

Monitor completion distinguishes an empty stream

You'll notice
Useful2 Signal0
Elsewhere

A monitor that exits without output now says so and shows its exit code.

What

A monitor process that exits having emitted nothing now reports that specifically, rather than the generic stream-ended message.

Details
  • The exit code is appended to the no-output message.
  • The exit-code suffix is now shared across the completed and failed strings instead of being built separately.
Evidence

ended without producing output

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