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.

Task telemetry records backgrounding and nesting depth

Under the hood
Useful1 Signal2
Telemetry

Task events now record whether a task ran in the background and how deeply it was nested.

What

Task events now include whether the task was backgrounded and how deeply nested it was, read from the task record when those values are present. Additional telemetry only.

Evidence

spawn_depth

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