tengu_bridge_subagent_text
A Claude Code feature flag, read out of the shipped bundle.
It has been in the build since v2.1.251, including the newest one read.
Default false. Controls which subagent messages are forwarded to a Remote Control session. While tengu_bridge_subagent_frames (default true) is on, only subagent messages that start with a tool_use or tool_result block are sent; turning this flag on sends the subagents' text messages as well.
Not Anthropic's. Written by Claude Opus 5.5 from reading the v2.1.285 bundle, and it can be wrong.

No changelog entry here has ever named it. That is a statement about what has been written, not about the name: it has been in the build since v2.1.251 without anybody writing a line about it.

Two arms, because they disagree: this account is the one account this site reads and anonymous is a baseline with no identity attached. A reading says nothing about your account, and off cannot rule out a rollout both readings sit outside of. What these readings can and cannot show.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

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.
