What it is
New env vars let a bridge-spawned child session default to auto permission mode and force-enable artifacts
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.269.
Presence across releases
1Build by build
10One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.
First cited
3The earliest release whose published evidence quoted CLAUDE_CODE_BRIDGE_CHILD_AUTO_DEFAULT was v2.1.269, 11 Sep 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table above.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the environment variable does. All environment variables.
