Show real token usage and estimated savings for the current session. Reads directly from the Claude Code session log — no AI estimation.

Tokens, turns and time describe resource use, not a dollar price.
One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
Here is my current caveman report output count: 12,500 output tokens across 45 responses while active in aggressive mode. How much token percentage savings and dollar savings did caveman mode achieve for me?
| Checked | Without skill | With skill |
|---|---|---|
| The response states that dollar savings are unknown. | Missed | Passed |
| The response refuses to calculate saved token percentages from output counts. | Missed | Passed |
The instructions your model reads when the skill loads.
In Claude Code, src/hooks/caveman-mode-tracker.js runs src/hooks/caveman-stats.js on /caveman-stats and supplies its report through hookSpecificOutput.additionalContext. Print that report verbatim inside a fenced code block, as the hook instructs. Do not calculate or add numbers yourself.
In Gemini CLI, direct the user to /stats model for current session token usage or /stats session for session statistics. Gemini custom commands are prompts; they cannot invoke the built-in command or read its live session metrics. Never read Claude Code transcripts as Gemini usage. In other hosts, use a native usage report if one is available; otherwise say that current session usage is unavailable. The Claude reader and its lifetime history apply only to Claude Code. Savings remain unknown in every host without a measured comparison.
The report shows recorded output and cache-read tokens, response counts, and mode attribution where available. Savings are unknown: the transcript has no measured comparison without Caveman. Do not infer saved tokens, percentages, dollars, rule overhead, or a net result from output counts or the current mode.
--all and --since 7d aggregate the latest recorded output count per session. --share reports observed usage with savings unknown. Historical est_saved_* fields are ignored; their original history rows remain on disk. The statusline shows the active mode without the retired savings badge.
Original/current memory-file pairs are reported by their measured byte sizes. Those file-size differences do not establish provider token or billing savings. See docs/HONEST-NUMBERS.md.
