cost-ledger

A Claude Code mod in bobtat/claude-plugins

Tracks what Claude Code costs: session, calendar-week and calendar-month totals with the month's pace and week-over-week change, a /costs pane with a spend calendar, the most expensive prompts and what filled the context, plus prompt-cache awareness: a cache warm/cold countdown, warnings before a prompt, model switch or large write re-caches the context, a per-category breakdown priced at list or your own (e.g. AWS) rates, per-project and subagent splits, budget alerts, CSV export and a /costs doctor self-check, the cache lifetime learned from Claude Code's own pricing, what a cold re-cache will cost before you resume, and an optional keep-alive that holds the cache warm while a session sits idle
