tengu_bridge_child_auto_mode
A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.269, including the newest one read.
New unreleased scaffolding tags some spawned bridge sessions as 'rc-child' behind a feature gate, but the other triggers are hardcoded off
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.269.

First cited
3The earliest release whose published evidence quoted tengu_bridge_child_auto_mode 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 below.
Presence across releases
1Build by build
47One 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.
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 feature flag does. All feature flags.
