About this mod
The author developed optimAIzr using Claude Code to identify wasteful Claude usage costs and has tried it in their own sessions. With Claude Code's new mod support, the author integrated it directly into the workflow: it can display the cost per conversation turn and 5-hour runway, automatically switch from Opus to Sonnet when sufficient budget is saved, and show token burn rate, savings, and cache hit rate via a real-time HUD. A special feature is that it does not blindly switch models—for long conversations, it first calculates the cost of reloading context before deciding whether the switch is worthwhile. The project is free and open source, and can be installed directly via the plugin marketplace.
