Context Compaction Visualizer: See Exactly What Your AI Agent Forgot Before It Costs You

A visualizer for context compression in multi-turn AI agents — helps you see what gets dropped when context limits hit.

Title is clickbait ("before it costs you"), but the body suggests a real technical tool addressing a concrete failure mode in multi-turn AI workflows. Need more substance in the body to assess properly, but the premise is relevant and actionable.
