A flag decides whether the file-delivery tool is held back from the initial tool list.

tengu_wise_star compiles in off, so the tool is not deferred here.

Feature flag
tengu_wise_star Gate removed from the code

This release deleted the gate from the code while it was still reading on for the account this site reads, so the code path no longer asks a flag before running.

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A new server-controlled flag, tengu_wise_star, decides whether the tool that delivers files such as screenshots, reports and artifacts to you is held back from the initial tool list and offered later instead. The value compiled into this build is off, meaning the tool is not deferred; the live answer comes from remote config.

Details
  • The flag is read once and cached on the session, so it cannot change part-way through a session.
  • It feeds the tool's shouldDefer property; the tool is described internally as delivering files to the user.
Evidence
