Track your Claude Code and Codex CLI API spend before it triggers an international incident.
"Tobias! Did you ralph loop a cleanroom implementation of FireFox?"
A Claude Code skill that calculates what your usage would cost at pay-as-you-go API prices, so you can see how many dollarydoos your AI-assisted coding sessions are actually worth — and whether your subscription plan is saving you from a boot to the head.

- Token breakdown by model (input, cache writes, cache reads, output)
- Total API cost at current pay-as-you-go rates
- Comparison against your subscription plan (Pro $20/mo, Max $100/mo, Max $200/mo)
- Daily cost bar chart so you can spot the days you went full Tobias
- Active time estimate with $/hour rate
- A reminder that prompt caching is saving you from financial ruin
- Data coverage warnings when you ask for more history than exists
- Estimated spend from Codex's sqlite database (
~/.codex/state_5.sqlite) - Daily breakdown with session counts
- Caveats printed inline because honesty matters:
- Codex only logs total tokens (no input/output split) — uses 80/20 estimate
- No cache breakdown available
- Uses current gpt-5.3-codex pricing; older sessions may have been cheaper
On first use, you'll be asked which plan you're on. Your choice is saved to config.json so the Bureau of Dollarydoo Investigation doesn't have to ask again.
At current API prices, a typical hour of Claude Code usage costs about 8-9 dollarydoos. A particularly vigorous ralph loop session can easily crack 100 dollarydoos in a single day.
Codex is even spicier — a heavy day can run 300+ dollarydoos at API rates.
The Max plan exists specifically for people who would otherwise be calling the embassy.
