This is a great framework to experiment with memory architectures.
Everything the author says about memory management tracks with my intuition of how CC works, including my perception that it isn't very good at explicitly managing its own memory.
My next step in trying to get it to work well on a bigger game would be to try to build a more "intuitive" memory tool, where the textual description of a room or an item would automatically RAG previous interactions with that entity into context.
That also is closer to how human memory works -- we're instantly reminded of things via a glimpse, a sound, a smell... we don't need to (analogously) write in or search our notebook for basic info we already know about the world.
