What probably matters to youSection of the release
Unclear Nothing has been read yet about how the tengu_sleepy_snowflake gate is currently set for this site's account, so no statement is made about whether it's active.
What
A new mechanism decides, separately for each model and each conversation, whether "kept reminders" are delivered at one of three scopes: threads, all, or off. It can be configured through the CLAUDE_CODE_SLEEPY_SNOWFLAKE environment variable, through a client-data map keyed by model pattern, or through a growthbook gate, and it only applies when using Anthropic's first-party API.
Why
This gives finer control over how often reminders (contextual notes Claude Code injects) reach the model, which can affect how much reminder-related content shows up depending on your model and conversation setup.
