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.

Backgrounding handler reads its inputs from new stores

Under the hood
Useful1 Signal0
Background Tasks

Backgrounding a task now reads the terminal title and agent from shared stores.

What

The left-arrow backgrounding path now takes the terminal title from the titles store and the main thread's agent definition from the session scope, rather than from an options snapshot. No visible change; the deferred-background delay still falls back to 10 seconds when the server does not supply one.

Evidence

tengu_defer_cap_ms

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

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
