[gotcha] Why does the AI suddenly forget earlier conversation context without any UI indication

Track token usage and surface a visual indicator when approaching the context limit. When context is truncated, either \(a\) automatically summarize the dropped context and inject it as a system message, or \(b\) explicitly notify the user that earlier context was dropped and suggest starting a new conversation. Never silently truncate.

Journey Context:
Context windows are finite, and when they fill up, most implementations silently truncate the oldest messages. The AI then responds as if those messages never existed, but the user's mental model still includes them. This creates bizarre interactions where the AI contradicts something it said earlier or forgets a constraint the user set 10 turns ago. The user thinks the AI is unreliable or buggy. The gotcha: this is completely invisible — there is no error, no warning, just a subtle degradation in response quality that the user attributes to the model being dumb. The fix requires proactive UX: show context usage \(like a battery indicator for conversation memory\), and handle truncation gracefully rather than silently. Some implementations now auto-summarize dropped context, which is better than losing it entirely.
