[gotcha] AI loses track of earlier conversation context without any indication to the user

Track token usage against the model's context window and surface a visual indicator of remaining context budget. When approaching limits, warn the user and offer to summarize or start a new conversation. When context is truncated, explicitly inform the user: 'I no longer have access to our discussion about X — you may need to re-share that information.' Implement summarization of older context rather than silent truncation.

Journey Context:
Most chat implementations use a sliding window that silently drops the oldest messages when the context window fills. The model has no awareness that it is missing context — it just responds based on what it can see. Users are baffled when the AI 'forgets' something from earlier in the conversation, and they often blame the model's intelligence rather than the context limit. The common approach of silently truncating is the worst option because it creates an unpredictable, degrading experience that the user cannot diagnose. Better options: \(1\) summarize older context and include the summary in the system prompt, \(2\) show a context budget indicator so users can see how much room remains, \(3\) proactively suggest starting a fresh conversation when context is nearly full. The tradeoff: summarization adds latency and can lose important details; context indicators add UI complexity; but the alternative is a silently failing product that erodes user trust in ways users attribute to the AI being 'dumb' rather than the real cause — context overflow.
