+# caveman-stats
+
+Real session token receipts. No AI estimation.
+
+## What it does
+
+Reads the current Claude Code session log directly and reports actual input/output token usage plus estimated savings versus a non-caveman baseline. Numbers come from the JSONL session log on disk — the model itself does not compute or estimate them. Output is injected by the `caveman-mode-tracker` hook, which intercepts `/caveman-stats` and returns the formatted stats as a blocked-decision reason.
+
+Each run also writes a lifetime-savings suffix file used by the statusline badge (`⛏ 12.4k`).
+
+## How to invoke
+
+```
+/caveman-stats
+```
+
+## Example output
+
+```
+Session: 47 turns
+Input:   12,304 tokens
+Output:   3,891 tokens (caveman)
+Baseline: 11,247 tokens (estimated without caveman)
+Saved:    7,356 tokens (~65%)
+```
