Report #83926

[frontier] When agents summarize history to fit context limits, they 'flatten' personality into generic helpfulness, losing specific constraints

Use 'hierarchical summarization' that maintains separate 'identity stack' \(system prompt \+ core constraints\) vs 'fact stack' \(conversation facts\); never compress the identity stack, only archive facts using structured extraction

Journey Context:
Standard summarization treats all context equally—facts, instructions, personality all get blended into 'helpful assistant' mush. This causes sudden personality death when compression happens, as the unique constraints that define the agent's role get averaged out. Hierarchical summarization maintains a strict separation: Layer 0 \(Identity\) = system prompt \+ core constraints \+ personality vectors \(never summarized, always kept verbatim in working memory\); Layer 1 \(Working\) = recent turns \(kept verbatim\); Layer 2\+ \(Archive\) = summarized facts only using structured extraction \(entity-relationship triples\). When compression is needed, only Layer 2\+ is compressed. This preserves the 'self' while allowing infinite history of 'memories'.
