**Always use Claude at its best** — monitor model intelligence in real-time so you know exactly when quality starts to drop.

Why Context Stats?

Research shows that LLM quality degrades as the context window fills up — even the best models lose retrieval accuracy at longer contexts. But you can't see this happening. Context Stats makes it visible:

• Model Intelligence (MI) - A benchmark-calibrated score (1.000 → 0.000) that tracks how much quality has degraded, with per-model profiles for Opus, Sonnet, and Haiku
• Know your zone - See if you're in the Smart Zone, Dumb Zone, or Wrap Up Zone
• Track context usage - Real-time monitoring with live-updating ASCII graphs
• Get early warnings - Color-coded alerts tell you when to start a fresh session
• Per-model awareness - Opus retains quality longer than Sonnet, which degrades faster than Haiku. MI reflects this automatically

Context Zones

Zone	Context Used	Status	What It Means
🟢 Smart Zone	< 40%	Optimal	Claude is performing at its best
🟡 Dumb Zone	40-80%	Degraded	Context getting full, Claude may miss details
🔴 Wrap Up Zone	> 80%	Critical	Better to wrap up and start a new session
