tengu_teleport_permission_mode_refused

A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.299 and was gone by v2.1.300.

Nobody has written a line about this one. It is not in any of Anthropic's reference tables and no changelog entry here carries a description of it. It is in the build, which is the whole of what this page can claim.

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 v2.1.299 without anybody writing a line about it.

No release here has a gate table behind it for this flag. Most published releases have none at all: the readings exist only for versions the pipeline captured flag state on.

The earliest release whose published evidence quoted tengu_teleport_permission_mode_refused was v2.1.299, 14 Oct 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.
