A gated cleanup step now removes stray duplicate 'waterfall' messages from the conversation transcript
Claude Code can now strip out certain junk entries from the conversation transcript: a stray empty assistant message that appears right after a given point, and a message that is immediately followed only by system messages and matches a specific pattern. This is a new, more general cleanup step than the one covered before, and it only runs when a setting called tengu_silly_waterfall is turned on for the account.
The flag was off for both this site's account and the general population, and no reading has been taken under this release yet.
When enabled, this keeps the visible conversation history free of leftover or duplicated entries that don't belong, so the transcript reads cleanly.
tengu_silly_waterfall 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 v2.1.273: 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 v2.1.273. 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.
