[gotcha] AI behavior silently degrades as conversation context approaches token limits

Implement proactive context window monitoring. Track cumulative token usage and surface a context health indicator to users. Implement graceful degradation by summarizing older messages or pruning less relevant turns before quality degrades. Never let the model silently drop system instructions without notifying the user.

Journey Context:
As conversations grow the context window fills up with no error or warning. The model just starts ignoring earlier system instructions losing constraints and producing lower-quality responses. This is especially insidious because degradation is gradual: the model doesnt refuse or error it just gets subtly worse. Users report the AI was great at first but now its terrible without understanding why. The root cause is that most APIs silently truncate older messages or the models attention dilutes across too many tokens. The fix requires proactive monitoring: track token counts per message using tiktoken or the API usage fields and warn at roughly 80 percent capacity. Summarization loses detail; pruning loses context; suggesting a new chat feels like losing work. The best approach combines all three with user control: show what is being retained let users pin important context and auto-summarize older turns.
