# Tails Stats
Run the footprint script from the project root and report its result:
```bash
node "${CLAUDE_PLUGIN_ROOT}/scripts/stats.js"
```
If `${CLAUDE_PLUGIN_ROOT}` was not substituted (non-Claude hosts), run `scripts/stats.js` from the LLM_Tails checkout with the project as the current directory. If the script cannot be found, say so; do not estimate numbers yourself.
## Output
Show the script output as-is in a code block. At most two lines after it, only if useful:
- Map near its cap or empty → mention `TAILS_MAP_CHARS` / `TAILS_MAP=0`.
- Footprint matters more than strictness → `/tails lite` costs about the same; the cost is the rules text, not the level.
These numbers are the cost side only. Do not claim savings here; `/tails-gain` shows the benchmark examples.
## Boundaries
Read-only. Changes nothing. One-shot.
"stop tails-stats": cancel.
