A Claude Code feature flag, read out of the shipped bundle.
It was in the build from v2.1.138 and was gone by v2.1.193.
Default false. Its value is recorded as stripAllBashFlag on the tengu_auto_mode_decision telemetry event sent when the auto mode classifier reviews a tool call; the fast-path and subagent-handoff decision events do not carry it, and no other code reads the flag in this version.
Not Anthropic's. Written by Claude Opus 5.5 from reading the v2.1.191 bundle, and it can be wrong.

The earliest release whose published evidence quoted tengu_bash_allowlist_strip_all was v2.1.97, 8 Apr 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.

One 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.
