[gotcha] Long conversations silently degrade AI output quality as context fills, with no signal to the user

Implement a context health indicator that tracks approximate token usage relative to the model's context window. Warn users when approaching 70-80% of capacity. Offer conversation summarization or a 'fresh start' option before quality degrades. If you must truncate, summarize the truncated messages rather than silently dropping them, and inform the user that earlier context has been condensed.

Journey Context:
As a conversation grows, the model's context window fills up. Most implementations handle this by silently truncating the earliest messages to fit new ones within the token limit. The user has no idea the AI has 'forgotten' earlier context. The AI doesn't say 'I no longer remember what we discussed 20 messages ago' — it just responds without that context, often contradicting earlier agreements or losing critical constraints. This is especially dangerous in coding assistants where early architectural decisions get silently dropped, leading to suggestions that violate established patterns. The degradation is gradual and the AI still produces confident-sounding output, so users don't realize what's happening. They blame the model or the product rather than recognizing it's a context management issue.
