What

The polling interval for the bridge connection (used in remote/cloud sessions) is now dynamically configurable from the server rather than being hardcoded.

Details
  • Poll interval is now controlled by the tengu_bridge_poll_interval_ms feature flag, with a default of 1000ms and a floor of 100ms
  • The flag value is cached and refreshed every 5 minutes (300,000ms TTL)
  • The block_ms parameter was removed from work-poll requests, simplifying the client-server protocol
  • These changes allow Anthropic to tune remote session responsiveness server-side without requiring client updates
Evidence

New cached config reader KL1() at line ~532330 (search for "tengu_bridge_poll_interval_ms")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.58: no gate table built for this version

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.

What has happened since
Flag reading moved The flag server now returns null for tengu_bridge_poll_interval_ms, 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.
