[gotcha] AI quality silently degrades as conversation length approaches context window limits, with no UI indication

Track token usage per conversation and surface a visual indicator of remaining context capacity. When approaching 80% of the context window, warn the user that earlier context may be lost. Implement automatic summarization of older messages before they fall out of the window. Never silently truncate — either summarize or explicitly tell the user a new conversation is needed.

Journey Context:
Users expect the AI to remember the entire conversation, but context windows are finite. As the conversation grows, the model doesn't say 'I can't remember what you said 50 messages ago' — it just silently starts ignoring earlier context. The responses become subtly less contextual, missing references to earlier decisions, constraints, or preferences. Users perceive this as the AI 'getting dumber' rather than hitting a hard technical limit. This is a gotcha because there's no error, no exception, no obvious failure — just a gradual quality decline that users attribute to the model itself. The fix requires making the invisible visible: show context usage, proactively summarize, and set expectations about conversation length.
