I've tried a bunch of these "memory" systems and they aren't there yet.
There is, currently, a tension between memory, and context pressure on the coding agent. There have been multiple studies now that tools like codex and claude code get worst at coding as their context window fills up.
As you start adding skills, memory systems, plugins and then a large code base on top of it, I've personally seen the agent start to flounder pretty quickly.
We need a way for agents to pull adhoc memory as they are going along, in the same way we do, rather than trying to front load all the context they might need.
