Why Context Fog Matters
Long Conversations
After 20+ messages, AI starts losing track. Fog check tells you when to reset or compress.
Multi-Topic Sessions
Switching between topics creates confusion. Detect when to create a clean handoff.
Code Reviews
Long code discussions drift. Know when the AI is confused about which file you're discussing.
