A Chrome extension that tracks how many messages are in your current Claude.ai chat and displays a water glass. When AI chat context gets full, responses become less accurate or start ignoring instructions. This extension gives you a simple visual warning before that happens. 🔵 Full (0–30 messages) — Full accuracy 🟢 Good (31–60 messages) — Still reliable 🟠 Watch (61–85 messages) — Monitor accuracy 🔴 Critical (86+) — Time for a fresh chat No data collected. No message content read. Free.

I built this after repeatedly running into the classic Claude problem — deleted code, contradictory answers, ignored instructions. It always happened around the same message count.
The extension counts your messages locally using DOM inspection — no content is read, nothing leaves your browser. The water glass empties as context fills up so you know when to start a fresh chat before things go wrong.
Would love feedback on whether the thresholds (30/60/85/86+) match your experience — especially for coding sessions vs. text conversations.
