Experience Compression Spectrum: an architectural framework unifying memory, skills, and rules in LLM agents
The Experience Compression Spectrum is a new architectural framework that positions memory, skills, and rules of LLM agents along a single axis of increasing compression — from episodic memory (5–20×) through procedural skills (50–500×) to declarative rules (1000×+). The analysis reveals that existing systems operate at fixed compression levels and that memory and skills do not communicate with each other.
