[frontier] When context is compressed or summarized for length, agent loses its personality and constraints

Implement tiered context management with three layers: \(1\) Identity layer—system prompt \+ crystallized identity \+ active constraint list—never compress, always preserve verbatim. \(2\) Decision layer—architectural choices, API contracts, naming conventions—compress by extraction into a structured artifact \(YAML/JSON\), not prose summary. \(3\) Interaction layer—questions, debugging, exploration—aggressively compress or discard. When context is trimmed, always trim from layer 3 first.

Journey Context:
Most context management strategies treat the entire context uniformly—they summarize everything or use a sliding window. But identity/constraint information has fundamentally different retention requirements than task history. The user's fourth debugging question about a null pointer doesn't need to be preserved, but the instruction to use TypeScript strict mode absolutely does. The key insight: the identity layer should actually GROW slightly over time as the agent accumulates session-specific conventions \(naming decisions, API patterns agreed upon\). The decision layer is the most nuanced—prose summaries lose critical details, but structured extraction preserves them. Teams implementing this in 2025 report near-zero identity drift even after aggressive context compression.
