Report #69863

[architecture] Saving every LLM interaction or tool output as a memory fills the context window and vector store with procedural boilerplate, drowning out actual insights

Apply a state-delta filter by only persisting memories that represent a change in state, a user preference, or a novel fact. Discard procedural steps, successful routine tool outputs, and conversational pleasantries.

Journey Context:
Agents naturally produce a lot of boilerplate \('I will now read the file', 'The file contains 50 lines'\). If the agent saves this as memory, subsequent sessions retrieve this useless procedural history. Memory should represent the delta—what changed or what was learned. If a tool execution succeeds and changes a file, the memory shouldn't be 'I ran the edit tool', it should be 'The auth bug in main.py was fixed by adding a null check'. Architecturally, this means the save\_memory tool's prompt must explicitly forbid saving conversational filler or routine tool outputs, focusing only on state mutations and extracted facts.
