[gotcha] AI response quality silently degrades in long conversations with no error signal

Monitor cumulative token usage proactively; surface a UI indicator when approaching context limits; offer automatic summarization or a context reset before quality degrades rather than after.

Journey Context:
Unlike traditional errors that produce visible failures, context window exhaustion produces subtly worse responses—the AI forgets earlier context, contradicts itself, or stops following system instructions. Users cannot diagnose why the AI got dumber. This is the most insidious failure mode: no error, no exception, just gradual quality collapse. The fix requires proactive monitoring: track cumulative tokens and before hitting limits either auto-summarize context or explicitly surface a message like 'I'm losing track of our earlier conversation—shall I summarize what we've discussed so far?' The gotcha is that there is no API error for this—it degrades gracefully in the worst sense.
