Memory plugins have been the most experimental corner of the ecosystem, and this week they started looking like infrastructure. The designs that gained traction all share one property: you can see what the agent decided to remember.
The approval gate becomes the norm
Memento continues to be the template. Writes are bounded, layered and gated behind approval, and a frozen snapshot is injected at recall time so results are reproducible. If you have been burned by a memory plugin that quietly accumulated noise over a long project, this is the design that fixes it.
Mnemon grows its graph
Mnemon is now running across several agent runtimes from a single binary. Graph-based recall rather than flat embedding search shows up in the results: related facts surface together, and the supervision step keeps the graph from filling with trivia.
Context is not memory
Worth repeating because the two get confused constantly. DSH Context tells you what is in the window right now and how it changed. Memory plugins decide what survives after the window closes. Installing one does not give you the other, and the strongest setups here have both.
Smaller notes
At File shipped a faster workspace index, which matters in large repositories. Deep Whale added a variant with higher contrast panels. DSH Free Search had intermittent rate limiting from its public backend, a reminder to move to a keyed provider if search becomes load-bearing.
Reading of the week
If you read one thing about agent memory, read the security guide section on the four permission surfaces. Memory plugins hold data about you by definition, and the place they hold it belongs in your evaluation alongside the retrieval quality.
