Claude Code adds an unreleased one-shot 'reannounce' request for remote tools, off by default
A new internal mechanism lets Claude Code send a single request, called remote_tools_reannounce, asking a connected worker to re-announce itself. It carries a worker_epoch and a deadline_ms value, and it is designed to fire only once per arming (a one-shot ask, not a repeating one). The path is controlled by a feature flag, so it only runs at all when that flag says to.
The flag involved, tengu_violin_scroll, currently returns off both for this site's account and for the general baseline, and no reading has yet been taken under this release.
This is internal plumbing for how Claude Code coordinates with remote tool workers, not something most users will interact with directly. Since the controlling flag is off, it does not currently change behavior for users on this site.
tengu_violin_scroll Off in both readingsThe flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
This account: off · anonymous baseline: off · compiled default in v2.1.280: off
These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
Read once, for one account on one subscription tier, against v2.1.280. It isn't a statement about your account. What a flag value here can and cannot tell you
A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
The finding does not say what a remote tools worker is used for or what happens once it reannounces, so the practical effect for users is…
