## Open now

- Nothing open on GitHub.

The members appear related to how the agent's stable (cacheable) prompt prefix is composed, including toolset-gated guidance that may affect prefix length, moving memory, session-search and skills guidance to a volatile tier, and sharing the prefix with delegate children. Titles alone do not establish the details or outcomes of these changes.
