Remote session worker gains a flag-controlled option to skip plain task-progress updates
The remote session worker gains skipPlainTaskProgress, tied to tengu_misty_spindle_enabled and off by default, which appears to filter plain task-progress updates

Unclear Exactly which progress updates are skipped when the option is on.
What
In a remote session, Claude Code runs on another machine, and a worker sends the session's events back over a connection. That connection gets a new option for task-progress updates. These are status messages about work in progress.
The worker connection gains a skipPlainTaskProgress option, off by default. Its name and the code around it suggest it filters out plain task-progress updates.
Both worker setups wire the option to the flag tengu_misty_spindle_enabled, which falls back to false. A flag is a switch Anthropic's server can turn on remotely.
The worker is also given isFirstPartyProvider.
One set of control message types, which included system/task_summary, gains one more entry.
For tengu_misty_spindle_enabled, the flag server returned off for this site's account and off for an anonymous baseline. No reading has been taken under this release yet.
Why
Nothing changes unless the server turns the flag on. If it does, remote sessions may send fewer plain progress updates.

The 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.

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.
Flag reading movedThe flag server now returns on for tengu_misty_spindle_enabled, read as this account.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.
