The only memory skill with rollback, cryptographic audit trails, and governed actions. 60+ commands covering 100% of Novyx Core — memory, drafts, knowledge graph, context spaces, time-travel replay, eval scoring, execution tracing, and policy-controlled actions.
Every other memory skill gives you save and search. Novyx gives you the full stack:
