NVIDIA tutorial: memory-driven self-model agent hits 90.9% vs 82.8% RAG baseline

An NVIDIA developer blog tutorial shows how to build a memory-driven Chief of Staff agent on NemoClaw that maintains a structured self-model of people, projects, priorities, and working patterns.

Derived knowledge lives in Markdown pages; a SQLite ledger tracks obligations, rankings, corrections, and audit events, separating evidence from judgment
An intent gate prioritizes obligations tied to stated user priorities over short-term urgency, while deterministic code enforces tier sizes, overflow behavior, and ranking order
Users correct agent judgments via an append-only audit trail; repeated corrections update an inspectable, editable preference policy
On the Agent Memory Benchmark, the self model lifts overall accuracy to 90.9% from an 82.8% agentic-RAG baseline and raises changed-fact tracking from 60% to 100%
Runtime enforcement uses NVIDIA OpenShell to sandbox file system, process, and network access, keeping credentials outside the sandbox
