tengu_claudeai_skills_sync_shared_round

flag in the build JSON

A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.282, including the newest one read.

How often Claude Code resyncs skills from claude.ai is now set by the server, and sessions can optionally share a recent sync

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.282.

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.

One row per unbroken stretch of one reading, newest first, from snapshots taken every twenty-five minutes or so. No longer carried is not off: it means the flag server stopped returning the gate at all, which is what a retired experiment looks like. The version column is what was installed when the reading was taken, not what caused it.

The earliest release whose published evidence quoted tengu_claudeai_skills_sync_shared_round was v2.1.282, 24 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.

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.
