Below: the paragraph from the book that builds this idea, then the diagram itself (Figure 5.1.), and a recap. About a minute of reading.
The curated snapshot is injected into the system prompt as a frozen snapshot at session start, and the session header shows usage percentages so you can see how full it is. The full log is never injected; the agent reaches into it with the session_search tool when a question needs an exact past detail.
Recap
- The idea: The two-store memory model: a small curated snapshot injected into every session, beside a lossless history searched on demand.
- The picture: Figure 5.1., from chapter 5 ("Persistent Memory: An Agent That Remembers You") of Hermes Agent Made Crystal Clear.
- Go deeper: the chapter builds this step by step, with recipes and sources at the end.
