Under the hood
New telemetry tracks how long startup waits on remote feature-flag fetches
What
Claude Code's startup process now records a tengu_startup_flag_fetch_wait telemetry event whenever it waits on fetching remote feature flags (settings that turn features on or off remotely, via a service called GrowthBook). The event notes where the wait happened (before tools are set up, or before context is set up), how long it waited, and whether the wait timed out.
Why
This gives visibility into how much startup time is spent waiting on remote flag fetches, which can help identify and address startup slowness caused by that step.
