# Caveman Stats

> Show real token usage and estimated savings for the current session. Reads directly from the Claude Code session log — no AI estimation. Triggers on /caveman-stats. Output is injected by the mode-tracker hook; the model itself does not compute the numbers.

This skill is delivered by `hooks/caveman-stats.js` (read by `hooks/caveman-mode-tracker.js` on `/caveman-stats`). The model does not need to do anything when this skill fires — the hook returns `decision: "block"` with the formatted stats as the reason. The user sees the numbers immediately.

## Output Report

After all main skill tasks complete, write a propose draft to the wiki.

### Steps

**1. Build the filename:**
- Format: `DDMMYY-<ten>.md`
- `DDMMYY` = today (e.g., `020626` for 2 June 2026)
- `<ten>` = 2–4 kebab-case words summarising what was done (e.g., `landing-page-coteccons`, `brand-kit-fintech`, `ingest-auth-spec`)

**2. Write** `llmwiki/wiki/draft/cave/DDMMYY-<ten>.md`:

```
# DDMMYY-<ten>
**Type:** draft
**Status:** proposed
**Tags:** <skill-name>, output-report
**Proposed:** YYYY-MM-DD

## What
<One sentence — what this skill invocation produced or decided>

## Output
<Key artefacts, files created/modified, or decisions made>

## Files
| File | Action |
|------|--------|
| `path/to/file` | created / modified |

## Notes
- Invoked via: `/<skill-name>` skill

## Origin
- **Draft:** `wiki/draft/cave/DDMMYY-<ten>.md`
- **Commit:** _(filled by verify-before-commit)_
- **Date promoted:** _(filled by verify-before-commit)_
```

**3. Update wiki index & log:**
- `llmwiki/wiki/index.md` — append one row: `| [DDMMYY-<ten>](draft/cave/DDMMYY-<ten>.md) | draft | YYYY-MM-DD |`
- `llmwiki/wiki/log.md` — append: `## YYYY-MM-DD — <skill-name> — <ten>`

> Skip only when the skill produces zero artefacts and zero decisions (e.g., a pure display mode like `/caveman-stats`).
