caveman-stats
Track Caveman Token Savings
Claude Code users need reliable token receipts without asking the model to estimate usage. This skill documents a hook-based command that reports session tokens and estimated savings from the local log.

Test it
Using "caveman-stats". User runs /caveman-stats during a Claude Code session.
Expected outcome:
A receipt-style summary shows session turns, input tokens, Caveman output tokens, baseline output estimate, and saved tokens.
Using "caveman-stats". User asks for a short explanation after viewing the stats.
Expected outcome:
The response explains whether the session used fewer output tokens than the estimated baseline.
Using "caveman-stats". Maintainer checks the statusline behavior after several sessions.
Expected outcome:
The workflow describes a lifetime-savings suffix that can appear in a statusline badge.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Review Session Cost
Check real token usage after a Claude Code work session and see the estimated Caveman savings.
Track Team Efficiency
Use receipt-style stats to discuss whether Caveman workflows reduce output tokens across similar tasks.
Validate Hook Output
Confirm that the /caveman-stats hook returns the expected token fields and statusline suffix behavior.
Try These Prompts
/caveman-stats
Run /caveman-stats, then summarize input, output, baseline, and saved percentage.
Use /caveman-stats to capture the current session, then explain how the savings affect this task's token budget.
Use /caveman-stats and review whether the current session has unusual output volume or low savings. Recommend one workflow adjustment.
Best Practices
- Run the command after meaningful work, when the session has enough turns to measure.
- Treat savings as directional estimates, not billing records.
- Keep Caveman hooks installed and versioned with the workflow that consumes the skill.
Avoid
- Using the numbers as exact invoice data.
- Running the command in an environment without the required hook.
- Comparing sessions with very different task scope as if they are equivalent.
