vamseeachanta Usage Tracker
When to Use This Skill
✅ Use when:
- Need to track tool/resource usage over time
- Generating usage reports (daily, weekly, monthly)
- Monitoring quotas or limits
- Analyzing usage patterns
- Building dashboards
❌ Avoid when:
- Real-time metrics (use proper monitoring tools)
- High-frequency events (>100/second)
- Sensitive data without encryption
Summary
$(generate_summary "$period" | sed 's/\x1b[[0-9;]*m//g')
Daily Breakdown
| Date | Opus | Sonnet | Haiku | Total |
|---|---|---|---|---|
| EOF |
for i in $(seq 6 -1 0); do
local date=$(date -d "$i days ago" +%Y-%m-%d)
local opus=$(grep "$date" "$USAGE_LOG" | grep "|opus|" | wc -l)
local sonnet=$(grep "$date" "$USAGE_LOG" | grep "|sonnet|" | wc -l)
local haiku=$(grep "$date" "$USAGE_LOG" | grep "|haiku|" | wc -l)
local total=$((opus + sonnet + haiku))
echo "| $date | $opus | $sonnet | $haiku | $total |" >> "$output"
done
cat >> "$output" << EOF
Recommendations
Based on current usage patterns: $(generate_recommendations)
Generated: $(date) EOF
echo "Report generated: $output"
}
