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 worktree isolation now reads CLAUDE_BG_ISOLATION from a captured environment copy.

CLAUDE_BG_ISOLATIONbgIsolation
What

The setting that decides whether background work runs in a separate worktree now reads CLAUDE_BG_ISOLATION from a captured copy of the environment rather than live process state. It still accepts worktree or none and otherwise falls back to the bgIsolation config value. A new comment documents how terminal recordings are addressed within a session folder.

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