Problem Statement

Claude Code sessions can silently grow to 1M token contexts, resulting in unexpected bills of $100+ within days. There is no in-session visibility into token consumption or cost — users only discover the damage after checking the billing dashboard.

Proposed Solution

Embed a live session token counter and running cost estimate directly into the existing daily/weekly usage dashboard that already tracks this data. Add a configurable threshold warning (e.g. at 50% and 75% of context limit) that surfaces in the Claude Code UI, prompting the user to /clear or compact. The data pipeline already exists — it just needs to be surfaced in-session rather than only post-hoc.
